i try run in cmd on windows 7 :

and cmd returns: error: not find or load main class test.class

thanks reading

when compile file, means know class name should same it's file name. did not use package in code file, first of should change command prompt path folder code file in it.

for example file in c:\javalab folder. first should change path: c:> cd javalab , then: c:\javalab> java test.class

if use package, test.java file should in path demonstrate in front of package keyword.

for example package is: package com.org.prog; file should in com\org\prog folder. change command prompt path before org folder , enter java command: java com.org.prog.test

be careful command prompt path should of org folder before enter java command run test.class.

be successful.
