How to create a class which is not inheritable and static in java?

Question

Can you please help me how to create a class which is not inheritable and should be static in behavior (Means we should not be able to create instance of it). I need this class to store constant values. Thanks.

Answer 1

public final class MyClass { 
    private MyClass() { }
}

The final keyword makes it not inheritable, and making the constructor(s) private will help stopping it from being instantiated.
