Java version history - Wikipedia. The Java language has undergone several changes since JDK 1. Since J2. SE 1. 4, the evolution of the Java language has been governed by the Java Community Process (JCP), which uses Java Specification Requests (JSRs) to propose and specify additions and changes to the Java platform. The language is specified by the Java Language Specification (JLS); changes to the JLS are managed under JSR 9. In addition to the language changes, much more dramatic changes have been made to the Java Class Library over the years, which has grown from a few hundred classes in JDK 1. J2. SE 5. Entire new APIs, such as Swing and Java. D, have been introduced, and many of the original JDK 1. Some programs allow conversion of Java programs from one version of the Java platform to an older one (for example Java 5. Java backporting tools). After the Java 7 release, Oracle promised to go back to a two- year release cycle.[1] However, in 2. Oracle announced that they would delay Java 8 by one year, in order to fix bugs related to Java security.[2]In September 2. Mark Reinhold, chief Architect of the Java Platform, proposed to change the release train to "one feature release every six months" rather than the current two- year schedule.[3][4]Java 8 is the only publicly supported version, while after public support periods of older versions has ended, non- public updates have been issued for Java 7 and earlier. Release. Year. JDK Beta. JDK 1. 0. 19. 96. JDK 1. 1. 19. 97. J2. SE 1. 2. 19. 98. J2. SE 1. 3. 20. 00. J2. SE 1. 4. 20. 02. J2. SE 5. 0. 20. 04. Java SE 6. 20. 06. There’s a total solar eclipse happening on August 21, 2017, and for the first time in nearly a hundred years, the Moon’s unabashed Sun-blocking power will be. Java SE 7. 20. 11. Java SE 8. 20. 14. Java SE 9. 20. 17. JDK 1. 0[edit]The first version was released on January 2. Welcome to the NetBeans Plugin Portal. Download, comment, and rate plugins provided by community members and third-party companies, or post your own. Gradle is an advanced general purpose build management system based on Groovy and Kotlin. Gradle supports the automatic download and configuration of dependencies or.Oak.[5][6] The first stable version, JDK 1. Java 1.[6]JDK 1. 1[edit]Major additions in the release on February 1. J2. SE 1. 2[edit]Codename Playground. The release on December 8, 1. J2. SE 5. 0 were rebranded retrospectively Java 2 and the version name "J2. SE" (Java 2 Platform, Standard Edition) replaced JDK to distinguish the base platform from J2. EE (Java 2 Platform, Enterprise Edition) and J2. ME (Java 2 Platform, Micro Edition). This was a very significant release of Java as it tripled the size of the Java platform to 1. Major additions included: [9]J2. SE 1. 3[edit]Codename Kestrel. The most notable changes in the May 8, 2. J2. SE 1. 4[edit]Codename Merlin. The February 6, 2. Java platform developed under the Java Community Process as JSR 5. Major changes included: [1. Public support and security updates for Java 1. October 2. 00. 8. Paid security updates for Oracle customers ended in February 2. J2. SE 5. 0[edit]Codename Tiger. The release on September 3. The number was changed to "better reflect the level of maturity, stability, scalability and security of the J2. SE".[1. 5] This version was developed under JSR 1. J2. SE 5. 0 entered its end- of- public- updates period on April 8, 2. November 3, 2. 00. Updates were available to paid Oracle customers until May 2. Tiger added a number of significant new language features: [1. Generics: provides compile- time (static) type safety for collections and eliminates the need for most typecasts (type conversion) (specified by JSR 1. Metadata: also called annotations; allows language constructs such as classes and methods to be tagged with additional data, which can then be processed by metadata- aware utilities (specified by JSR 1. Autoboxing/unboxing: automatic conversions between primitive types (such as int) and primitive wrapper classes (such as Integer) (specified by JSR 2. Enumerations: the enum keyword creates a typesafe, ordered list of values (such as Day. MONDAY, Day. TUESDAY, etc.); previously this could only be achieved by non- typesafe constant integers or manually constructed classes (typesafe enum pattern) (specified by JSR 2. Varargs: the last parameter of a method can now be declared using a type name followed by three dots (e. String.. lines)); in the calling code any number of parameters of that type can be used and they are then placed in an array to be passed to the method, or alternatively the calling code can pass an array of that type. Enhanced for each loop: the for loop syntax is extended with special syntax for iterating over each member of either an array or any Iterable, such as the standard Collection classes (specified by JSR 2. Improved semantics of execution for multi- threaded Java programs; the new Java memory model addresses issues of complexity, effectiveness, and performance of previous specifications[1. Static imports. There were also the following improvements to the standard libraries: Java 5 is the last release of Java to officially support the Microsoft Windows 9. Windows ME,[2. 1] while Windows Vista is the newest version of Windows that J2. SE 5 was supported on prior to Java 5 going end of life in October 2. Java 5 Update 5 (1. Java to work on Windows 9. Internet Explorer 5. Windows NT 4. 0.[2. Java 5 was first available on Apple Mac OS X 1. Tiger)[2. 3] and was the default version of Java installed on Apple Mac OS X 1. Leopard). Public support and security updates for Java 1. November 2. 00. 9. Paid security updates for Oracle customers ended in April 2. Versioning change[edit]This version introduced a new versioning system for the Java language, although the old versioning system continued to be used for developer libraries: Both version numbers "1. Java 2 Platform Standard Edition. Version "5. 0" is the product version, while "1. The number "5. 0" is used to better reflect the level of maturity, stability, scalability and security of the J2. SE. This correspondence continued through later releases (Java 6 = JDK 1. Java 7 = JDK 1. 7, and so on). Java 5 updates[edit]Release. Release date. Highlights. Java SE 5. 20. 04- 1. Metadata, generic types, autoboxing and auto- unboxing of primitive types, enhanced for loop, enumerated types, static import, formatted I/O, varargs, and concurrency utilities. Improved startup time and memory footprint. Sharing of read- only data between multiple running JVMs. Remote monitoring and management. A new JVM profiling API. Programmatic generation of stack traces. Support for XML 1. Namespaces, XML Schema, SAX 2. DOM Level 3, and XSLT with a fast XLSTC compiler. Unicode 4. 0 support. Java SE 5 Update 1.

Java SE 5 Update 6. Prior to this update, an applet or application could specify the version of the JRE on which it would run. This has changed. All applets are executed with the latest JRE version. Java SE 5 Update 7. Several bugs were fixed and performance enhancements were made. Java SE 5 Update 8. Several bugs were fixed and performance enhancements were made. Java SE 5 Update 9. This release fixes several minor regressions. Java SE 5 Update 1. An implementation of the epoll I/O event notification facility, supported by Linux 2. Many bugs were fixed. Java SE 5 Update 1.

A security vulnerability in the JRE allowing network access restrictions to be circumvented was fixed. Several other security issues and minor bugs were fixed. Java SE 5 Update 1. Java SE 5 Update 1. Several crashes due to heap buffer out- of- bounds were fixed, along with several other bugs. New root certificates from AOL, Digi. Cert, and Trust. Center are now included. Java SE 5 Update 1. This release fixes several security flaws, such as Do. S vulnerabilities, buffer overflows, and other bugs which could lead to crashes or which would give applets access to certain system resources. These vulnerabilities were located in Java Web Start, in the Java Management Extensions (JMX) Management Agent, and in the functions for handling XML data. Java SE 5 Update 1. The UTF- 8 charset implementation was updated to handle the non- shortest form of UTF- 8 byte sequences, introducing an incompatibility from previous releases. New root certificates were added. Many bugs were fixed. The Gradle build system- Tutorial. Gradle also offers tasks for introspection of Gradle itself, so a Gradle project can be analyzed by using Gradle’s default tasks. A good example is the tasks task, which shows the available tasks of a project. When typing gradle - q tasks, a list of tasks is shown. This command lists the base tasks even without an build. Gradle also tries to give some guidance for the usage of invoked tasks, as shown in the bottom of the console output. The gradle tasks - -all command would also list dependent tasks, which are invoked before the actual task. When running gradle tasks - -all the output looks quite similar to the one before, except of the init task, which depends on the wrapper task. In the The Gradle build file - build. Hello Gradle'. }When running the gradle - q tasks task with this build. Other tasks". Tasks without a group are considered as private tasks. For instance, the Gradle Task View of the Eclipse Gradle Plug- in does not show such tasks. But they can be shown by activating the right entry in the view’s menu. Groups can be applied with the group property and a description can be applied by using the description property. In case the group already exists the hello task is added to it. If the group does not exist, it is created. The hello task greets Gradle by saying "Hello Gradle"'. Hello Gradle'. println 'Bye bye Gradle'. Gradle has different phases, when working with tasks. First of all there is a configuration phase, where the code, which is specified directly in a task’s closure, is executed. The configuration block is executed for every available task and not only for those tasks, which are later actually executed. After the configuration phase, the execution phase then runs the code inside the do. First or do. Last closures of those tasks, which are actually executed. Specifies. Code. For. Configuration. Phase {. Configuration phase task example.'. I always get printed even though, I am not invoked'. Unrelated. Task {. I am in the do. Last execution phase'. When running gradle - q another. Unrelated. Task the following is printed: I always get printed even though, I am not invoked. I am in the do. Last execution phase. The first statement comes from the configuration phase in which the task definition of the only. Specifies. Code. For. Configuration. Phase is evaluated. Gradle allows the definition of default tasks in the build file. These are executed, if no other tasks are specified. Tasks can also define their dependencies. Both settings are demonstrated in the following build file. Tasks 'clean', 'compile'. Executing the clean task'. Executing the compile task'. On: 'compile') {. I'm not a default task!". Other {. println "I want to clean up before running!". Other. depends. On clean, compile. Hooking into predefined task executions for default tasks or tasks from plug- ins can also be done by using the depends. On method. For instance when certain things have to be done right after the compilation of java code: apply plugin: 'java'. After. Compile. Java(depends. On: 'compile. Java') {. This will be invoked right after the compile. Java task is done'. An alternative to creating a new task, which depends on the. Java. do. First { println 'Another action applied to the "compile. Java" task' }. compile. Java. do. Last { println 'Another do. Last action is also applied' }When running the java. Compile task all actions, which have been. Compile task, are run one by. Skipping tasks can be done by passing a predicate closure to the only. If method of a task or by throwing a Stop. Execution. Exception. Hello Eclipse'. // #1st approach - closure returning true, if the task should be executed, false if not. If {. project. has. Property('using. Eclipse'). Stop. Execution. Exception() like this. First {. if(! using. Eclipse) {. throw new Stop. Execution. Exception(). Tasks depending on the eclipse task will be run even, if a Stop. Execution. Exception is thrown. You can access system variables. For example, to get the user home directory use the following: def home. Path = System. properties['user.
