Word Reverse Program

How To Reverse The Order Of  Words In A Given Input String.

Input: "My name is Darga "

Output: "Darga is name My"

package praticeprogrms2;

public class WordReverse

{

    public static void main(String[] args)

    {

        String input = "My name is Darga";

        String output = reverseWords(input);

        System.out.println("Input : " +input);

        System.out.println("Output : " +output);

    }

    public static String reverseWords(String input)

    {

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

        StringBuilder reversed = new StringBuilder();

        for (int i = words.length - 1; i >= 0; i--)

        {

            reversed.append(words[i]).append(" "); // Append words in reverse order

        }

        return reversed.toString().trim(); // Remove the trailing space and return the result

    }

}

Output :

Input : My name is Darga

Output : Darga is name My

Explanation:

1. The reverseWords function takes the input string as a parameter.
2. It uses the split method to break the input string into an array of words, splitting at each space.
3. A StringBuilder named reversed is used to build the reversed word order.
4. A loop runs through the array of words in reverse order (from the last word to the first).
5. Each word is appended to the reversed StringBuilder, followed by a space.
6. Finally, the trim method is called to remove the trailing space, and the reversed string is returned.
