How do I handle null in switch statement in java?

For example when I have class like this:

public class SwitchWithNull {

    public static void main(String[] args) {
        String name = null;
        switch (name) {
            case null: {
                System.out.println("Case 1");
            }
        }
    }
}

With this example when I try to compile it I have 2 compilation errors from Intellij Idea:

  • Dereference of 'name' will produce 'NullPointerException'
    screenshot:

  • Constant expression required

The question is - what is the correct way of handling the null in switch statement in java?

I know that I can use if statement, but what about switch with null?
