Java is the name of a programming language created by Sun Microsystems. This company was bought out by Oracle Corporation , which continues to keep it up to date. It is designed to be platform-independent, which means that code written in Java can run on any device or operating system that has a Java Virtual Machine JVM installed. This makes Java a popular choice for developing cross-platform applications and games. Additionally, Java has a large and active community, and a wide range of libraries and frameworks available for use. Being an LTS version means that it will continue getting updates for multiple years. Being an open-source platform, Java isn't just supported by Oracle, e.

Java is a set of computer software and specifications that provides a software platform for developing application software and deploying it in a cross-platform computing environment. Java is used in a wide variety of computing platforms from embedded devices and mobile phones to enterprise servers and supercomputers. Java applets , which are less common than standalone Java applications, were commonly run in secure, sandboxed environments to provide many features of native applications through being embedded in HTML pages. Writing in the Java programming language is the primary way to produce code that will be deployed as byte code in a Java virtual machine JVM ; byte code compilers are also available for other languages, including Ada , JavaScript , Python , and Ruby. Memory management is handled through integrated automatic garbage collection performed by the JVM. Regarding Oracle, it distributes Java 8, and also makes available e. Java 11, both also currently supported LTS versions. Oracle and others "highly recommend that you uninstall older versions of Java" than Java 8, [11] because of serious risks due to unresolved security issues. Oracle released the last free-for-commercial-use public update for the legacy Java 8 LTS in January , and will continue to support Java 8 with public updates for personal use indefinitely. Oracle extended support for Java 6 ended in December The Java platform is a suite of programs that facilitate developing and running programs written in the Java programming language. A Java platform includes an execution engine called a virtual machine , a compiler and a set of libraries ; there may also be additional servers and alternative libraries that depend on the requirements. Java platforms have been implemented for a wide variety of hardware and operating systems with a view to enable Java programs to run identically on all of them. The Java platform consists of several programs, each of which provides a portion of its overall capabilities.

Java has three kinds of comments : traditional commentsend-of-line comments and documentation comments. Documentation comments in the source files are processed by the Javadoc tool to generate documentation.

Java is a computer programming language. It enables programmers to write computer instructions using English-based commands instead of having to write in numeric codes. Like English , Java has a set of rules that determine how the instructions are written. These rules are known as its syntax. Once a program has been written, the high-level instructions are translated into numeric codes that computers can understand and execute. In the early 90s, Java, which originally went by the name Oak and then Green, was created by a team led by James Gosling for Sun Microsystems, a company now owned by Oracle. Java was originally designed for use on digital mobile devices, such as cellphones.

Garbage collection may happen at any time. There can be more than one class with a main method, but the main class is always defined externally for example, in a manifest file.

Once the applet has initialized itself, it is added to the AWT display hierarchy. Not to be confused with Java software platform , JavaScript , or Javanese language. Search inside document. The access modifiers , or inheritance modifiers , set the accessibility of classes, methods, and other members. Java runs on more than million personal computers worldwide, and on billions of devices worldwide, including mobile and TV devices. Besides the generic form, there are two other forms to declare an annotation, which are shorthands. Retrieved 13 March For the software package downloaded from java.

The exception is propagated upwards through the call stack until a matching catch block is found within one of the currently active methods.
