The Java Platform consists of two parts.

API (Java Application Programming Interface)

API is a collection of pre-written classes that we’ll used to develop new software.

Java Virtual Machine (JVM)

This is the environment for Java program. The JVM will run your programs build on Windows even in Linux!

When you install J2SE (JDK) then you'll get both of these. What J2ME and J2EE do is that they some more program files into J2SE. There's a bullet-in JVM in JDK. But, sometimes this JVM doesn't work with your browser. So, we install JVM seperately for better performance.
