When Java is installed, the runtime prompts you not to find or load the main class Com.sun.tools.javac.Main

This in our class have many classmates met, think of beginners This problem may be a few, I here on this question to say the reason and solution.

The reason is simple:

First, the JDK is the development environment JRE is the run Environment JDK installation package that contains the JRE.

Installing the JDK will prompt two installation directories, the first is the JDK installation directory, and the second is the JRE installation directory. The friend who encounters this problem is the one that installs the JDK with the JRE in the same directory.

Workaround:

JKD install two times directory selection in a different directory on it, than my JDK installation directory is the D:/JAVA/JDK JRE installation directory is D:/JAVA/JRE

So the problem is solved.

When Java is installed, the runtime prompts you not to find or load the main class Com.sun.tools.javac.Main
