How Do Java and Objective-C Differ in Handling Ranges within Switch Statements?

Using Ranges in Switch Statements: Java vs. Objective C

In Java, the switch statement allows for the evaluation of a single expression against multiple values. In each case block, exactly one value can be specified. Unlike Objective C, Java does not provide direct support for specifying ranges of values within a single case.

Consider the example provided:

switch (num) {
    case 1 .. 5:
        // Java does not support ranges in case statements
    case 6 .. 10:
        // Java does not support ranges in case statements
}

As noted in the question, this code will not compile because Java does not allow multiple values within a single case statement. Instead, a solution using if and else if statements is suggested:

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");
}

This approach uses an isBetween function to check if the value num falls within the specified range. While not as concise as a switch statement with ranges, it provides a valid alternative in Java.
