exception in thread ‘main’ java.lang.NoClassDefFoundError:

I found one another common reason. If you create the java file inside a package using IDE like eclipse, you will find the package name on the top of your java file like “package pkgName”. If you try to run this file from command prompt, you will get the NoClassDefFoundError error. Remove the package name from the java file and use the commands in the command prompt. Wasted 3 hours for this. — Abhi
