Java SE Development Kit lets you develop and deploy Java applications on desktops and servers. Java compiles applications into .class bytecode files instead of platform dependent executables, ensuring that the same code produces the same output in all systems. Hence, you can develop programs for Windows, and use them on other systems.
Good for improving system and web browsing operation.
Good software.
I downloaded it on Windows 7 Professional 64-bit and it installed and is working well.
