Both 32-bit and 64-bit platforms are supported. The downloads includes Java for Linux, Solaris and Windows. You can download Java 7 JRE and JDK from the following location:

More than 3 billion devices are powered by Java technology.1 programming language (TIOBE Programming Community Index).Expanded support for internationalization, including Unicode 6.0 support.A comprehensive I/O interface for working with file systems that can access a wider array of file attributes and offer more information when errors occur.A new multicore-ready API that enables developers to more easily decompose problems into tasks that can then be executed in parallel across arbitrary numbers of processor cores.Improved support for dynamic languages (including: Ruby, Python and JavaScript), resulting in substantial performance increases on the JVM.Language changes to help increase developer productivity and simplify common programming tasks by reducing the amount of code needed, clarifying syntax and making code easier to read.And it came after a lot of time but there has been a huge improvement in features and a lot of bugs have been fixed. This is the first major update after Oracle acquired Sun Micro Systems. We should note that before this long-running project, there were JDK Release Projects that released one feature and were then discontinued.Oracle has finally released Java 7 and JDK 7 for developers.

And, just like for Oracle, the JDK Project will also deliver new feature releases every six months. Initially, it was based only on the JDK 7, but since Java 10, the open-source reference implementation of the Java SE platform is the responsibility of the JDK Project. We should emphasize that OpenJDK is an official reference implementation of a Java Standard Edition since version SE 7. Note: the versions in italics are no longer supported. Let's take a look at the Java SE history: Oracle strongly recommends using the term JDK to refer to the Java SE (Standard Edition) Development Kit (there are also Enterprise Edition and Micro Edition platforms). It's thus named because it contains more tools than the standalone JRE, as well as the other components needed for developing Java applications. It contains a complete Java Runtime Environment, a so-called private runtime. JDK (Java Development Kit) is a software development environment used in Java platform programming.
