I found that when using switch case statement with an Enumeration as parameter. a new .class file called ClassName$1.class will be generated.

Can you explain to me the origin of this .class file ?

public class MayJavaApp{

    private static NewEnum ok;

    public String doSomthing() {
        NewEnum value=null;
        switch (value) {
            default: return "other";
        }
    }

}

The target directory contains:

MayJavaApp.class
MayJavaApp$1.class

Interesting. It's the switch that does it. The static field is irrelevant. – khelwood Dec 12 '17 at 11:35
@Dan My question is different from the other because I'm looking for the origin of this class – CHHIBI AMOR Dec 15 '17 at 10:49
The solution : because a Java enum implements implecitly Comparable – CHHIBI AMOR Dec 17 '17 at 16:21
