How Can I Handle Value Ranges in Java\'s Switch Statement?

Switch Statement with Value Ranges in Java

In Java, it's not possible to specify a range of values in a single case of a switch statement. The code example provided below won't work:

switch (num) {
    case 1 .. 5:
        System.out.println("testing case 1 to 5");
        break;
    case 6 .. 10:
        System.out.println("testing case 6 to 10");
        break;
}

Unlike Objective C, which supports ranges in switch statements, Java does not have such functionality. As an alternative, consider using if-else if statements:

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");
}

Here, isBetween() is a helper method that checks if a number falls within a specified range:

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

By using if-else if statements, you can evaluate multiple ranges and execute the appropriate block of code.
