Do you want to know how to download and install Java on a PC? This post from MiniTool Partition Wizard introduces the differences among JDK, JRE, and JVM and shows you how to get Java 32 bit & 64 bit downloads.


The full form of JDK is Java Development Kit, the full form of JRE is Java Runtime Environment, and the full form of JVM is Java Virtual Machine. Some people want to know the difference between the three items.

  • JDK: It is a software development kit. It contains tools required to write Java programs, and JRE to execute them. In other words, JRE is one of the subdirectories under JDK.
  • JRE: It is a software bundle that allows Java programs to run. It contains class libraries, JVM, and other supporting files. As you can see, JVM is one of the subdirectories under JRE.
  • JVM: It provides a platform-independent way of executing Java source code. With it, you can write a java program once and run it anywhere, saving lots of time.

For Java program developers, they will download and install JDK. But if you just need to run some Java software (like the Minecraft Java Edition), you just need to download the JRE. As for JVM, seldom people will download and install it separately.
