Is a switch executing all the cases without stopping?

Question

I\'m on Java 8v60. I tried to embed a switch regarding an exception group in a catch block. Apparently, the case are recognised, but once they get into the switch, they keep

The switch statements jump to the right value, and continue up to the end of other cases.

If you like to exit the switch statement you have to use a break (or return in some situations).

This is useful to handle situations in wich many values can be handled at the same manner:

switch (x) {
    case 0:
    case 1:
    case 2:
        System.out.println("X is smaller than 3");
        break;
    case 3:
        System.out.println("X is 3");
    case 4:
        System.out.println("X is 3 or 4");
        break;
}

If the case selection is also a final condition for a method you can return from it.

public String checkX(int x) {
    switch (x) {
    case 0:
    case 1:
    case 2:
        return "X is smaller than 3";
    case 3:
        return "X is 3";
    case 4:
        return ("X is necessary 4");
    default:
        return null;

    }
}
