Using switch statement with a range of value in each case?

Java has nothing of that sort. Why not just do the following?

public static boolean isBetween(int x, int lower, int upper) {
  return lower <= x && x <= upper;
}

if (isBetween(num, 1, 5)) {
  System.out.println("testing case 1 to 5");
} else if (isBetween(num, 6, 10)) {
  System.out.println("testing case 6 to 10");
}

The closest you can get to that kind of behavior with switch statements is

switch (num) {
case 1:
case 2:
case 3:
case 4:
case 5:
     System.out.println("1 through 5");
     break;
case 6:
case 7:
case 8:
case 9:
case 10:
     System.out.println("6 through 10");
     break;
}

Use if statements.
