Break Switch Statement

CODE

class BreakSwitch
{
    public static void main(String arg[])
    {
        int rating = 1; // rating out of 4
        
        switch(rating)
        {
            case 1:
                System.out.println("Poor"); // LINE A
                break;
            case 2:
            case 3:
                System.out.println("Average"); // LINE B
                break;
            case 4:
                System.out.println("Good"); // LINE C
                break;
        }
        System.out.println("After switch"); // LINE D
    
    }
}

OUTPUT

Poor
After switch

DESCRIPTION

Here rating is 1 hence LINE A and LINE D are executed. When break is encountered after LINE A, the control directly goes to the next statement after switch, which is LINE D, hence prints After switch.
When rating is 2 or 3, LINE B and LINE D are executed, when it is 4, LINE C and LINE D will be executed.

THINGS TO TRY

Remove break statements at LINE A, LINE B, LINE C and see the output. The output will be as shown.
Poor
Average
Good
After switch
Since there is no break all the cases will get executed.

Change the data type of rating to float. It shows a compilation error, since switch cannot function with float, double and long data types.
