J2SE 1.2 (JDK 1.2) (December 8, 1998): Re-branded as 'Java 2' and renamed JDK to J2SE (Java 2 Standard Edition).JDK 1.1 (February 19, 1997): Introduced AWT event model, inner class, JavaBean, JDBC, and RMI.JDK 1.0 (January 23, 1996): Originally called Oak (named after the oak tree outside James Gosling's office).JDK Alpha and Beta (1995): Sun announced Java in September 23, 1995.Since you are supposed to write Java Programs, you should install JDK, which includes JRE. JDK (Java Development Kit), which includes JRE plus the development tools (such as compiler and debugger), is need for writing as well as running Java programs. JRE (Java Runtime) is needed for running Java programs. On the contrary, JDK or Java Development Kit, as we mentioned above, is the pack of development tools that couldn't work without the JRE.Java Development Kit (JDK), officially named 'Java Platform Standard Edition ( Java SE)', which is freely available from Sun Microsystems (now part of Oracle), is needed for writing Java programs. In other words, the software necessary for any user to be able to run an app and doesn't contain any development tools. In other words, the virtual machine necessary to be able to run applications developed in Java and that offers us different versions for each operating system. JRE is the runtime environment of this language. What's the difference between JDK and JRE (Java Runtime Environment)? Javadoc: it's a tool in charge of creating documentation in HTML format based on the Java source code and the comments made by the developer.Appletviewer: it's the viewer for applets that can be used instead of a web browser.Java: it's the interpreter and the program that takes care of executing the bytecode.Javac: it's the Java compiler to turn the source code written by the developer into bytecode.Amongst the latter, the following are considered as the most important ones: The latter offers us a series of services and tools that simplify the development of software. The Java development environment for MacĪnd this Java JDK 8 SE provides the development environment required by any developer to create applications based on Java. It's present on millions of devices around the world, including computers, smartphones, and TV sets. You can create applications that, through a specific virtual machine for each operating system, can run on different platforms, whether Mac, Windows PC, Android. Java has become one of the most popular development languages in the world, mainly due to its portability.
