java classloader runtime error in netbeans

Question

When I run my project it shows this error

run:
`java.lang.SecurityException:` Prohibited package name: java.course
    at java.lang.ClassLoader.preDefineClass(ClassLoader.java:659)

Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" Java Result: 1

What can i do to solve this problem ?

Note:-Please simplify explanation because I'm still initially structured in the programming department and I am still in the tutorial.

You might need to include some code. it says `java.course` package. what is the code in the class? — hoss, Jun 14 '15 at 19:55

You can't use 'java' as name of a package. So java.course as name of the package isn't allowed. Try renaming the package
