Thread: switch case , check range

Hello guys,
i am totally new to java.How do i check INT range for switch case: ?

	int grade = 68;
		switch (grade) {
		case 100:
		System. out.println( "You got an A. Great job!" );
		break;
		case 80:
		System. out.println( "You got a B. Good work!");
		break;
		case ("60-79"):
		System. out.println( "You got a C. What went wrong?" );
		break;
		default:
		System. out.println( "You got an F. You’ll do well in Congress!" );
		}
}
}

You dont.
A switch case can only take constant values.

What you want is probably an if-then-else statement.

If you really want to torture yourself and anyone else looking at your code, you could do this:

int grade = 68;
 
switch (grade/10) {
//stuff
    case 6:
        System.out.println("60-69");
        break;
//stuff

Even more !?what?!

int grade = 68;
 
switch (grade/20) {
//stuff
    case 3:
        System.out.println("60-79");
        break;
//stuff

Just because you can, doesn't mean you should.

I agree, that's painful to look at, and no sane person should do that or suggest that anyone else do that.
