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

Switch Statement with Range of Values in Cases in Java

Java's switch statement allows you to match a variable against a set of constant values to execute specific code for each condition. However, it's not possible to specify a range of values for a single case, as illustrated in the example provided:

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;
}

Alternative Solution:

Since Java does not natively support ranges in switch cases, an alternative solution is to use a combination of if-else if statements. This approach involves creating a function to check if a given value falls within a specified range:

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

Using this function, you can construct a series of if-else if statements to determine which range the num variable belongs to and execute the corresponding code:

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");
}
