Say the first computer configuration environment
Installation of jdk1.8.0 _221
Program is to use the NetBeans IDE 8.2
Also by browsing to post their configuration of the environment variable, but in the CMD command line running always quote could not find the mistake or unable to load the main class


Program is installed in the default directory



Configuration of environment variables also posted
Create the JAVA_HOME

This is the path variable configuration inside

Created a system variable CLASSPATH



Environment variables can be configured after the show version of


Source files in D disk folder, but through the CMD command line would be an error


But if it is running under the NetBeans IDE 8.2, will show success



Also read many posts online, some said without package field, some said environment variable configuration has a problem, I have tried and still no solution, turn to the great god see me is where configuration has a problem,
