How to reverse the order of the words in a string with Java

Answer 1

public class ReverseWords {
    // Function to reverse an array of strings in place
    public static void reverseArray(String[] arr) {
        for (int i = 0; i < arr.length / 2; i++) {
            String temp = arr[i];
            arr[i] = arr[arr.length - 1 - i];
            arr[arr.length - 1 - i] = temp;
        }
    }

    public static void main(String[] args) {
        String input = "python java c c++";

        // Split the string into words
        String[] words = input.split(" ");

        // Reverse the array using the function
        reverseArray(words);

        // Join the words back into a single string
        String result = String.join(" ", words);

        System.out.println(result);
    }
}
