![]() The Java API is a collection of prepackaged libraries developers use to create Java applications. The JDK and the JRE share the Java Application Programming Interfaces ( Java API). In addition, the JDK provides tools for packaging and distributing your applications. With the JDK, you can compile programs written in the Java Programming language and run them in a JVM. The Java Development Kit (JDK) is a collection of tools for developing Java applications. Rich Standard Library - Java includes a vast number of premade objects that can be used to perform such tasks as input/output, networking, and date manipulation.Automatic Garbage Collection - Java automatically allocates and deallocates memory so programs are not burdened with that task.Object-Oriented - Java is an object-oriented language that take many of the features of C and C++ and improves upon them.Since applications run in a JVM, they can be run on many different operating systems and devices. Platform Independence - Java applications are compiled into bytecode which is stored in class files and loaded in a JVM.Java is an object-oriented programming language that includes the following features. With Java 7, Java applications run as desktop applications from the operating system, as a desktop application but installed from the Web using Java Web Start, or as a Web Embedded application in a browser (using JavaFX). All three are required to run Java applications on your computer. The JRE consists of the Java Virtual Machine (JVM), Java platform core classes, and supporting Java platform libraries. When you download Java, you get the Java Runtime Environment (JRE). Java is composed of a number of key components that, as a whole, create the Java platform. Java runs on more than 850 million personal computers worldwide, and on billions of devices worldwide, including mobile and TV devices. It is the underlying technology that powers Java programs including utilities, games, and business applications. Java is a programming language and computing platform first released by Sun Microsystems in 1995. Unzip the file and place the contents in a directory.
