Today, I'll talk to you about what to do if you can't find or load the main class in java. Maybe many people don't know much about it. In order to make you understand better, the editor summarizes the following content for you. I hope you can get something according to this article.

Compile a java program:

Package wanghf

Public class Helloworld {

Public static void main (String [] args) {

System.out.println ("Hello world!")

}

}

Compilation is normal:

D:\ workspace-java\ wanghf\ src\ wanghf > javac Helloworld.java

But execute an error message:

D:\ workspace-java\ wanghf\ src\ wanghf > java Helloworld.class

Error: main class Helloworld.class cannot be found or cannot be loaded

Looking for a lot of it is said to be the problem of classpath settings, but according to the modification will not solve the problem.

Finally, to find a solution, just remove the package wanghf section:

Public class Helloworld {

Public static void main (String [] args) {

System.out.println ("Hello world!")

}

}

Perform as follows:

D:\ workspace-java\ wanghf\ src\ wanghf > java Helloworld

Hello world!
