Here is the code to reverse a string in java word by word.

public class ReverseStringWords {
    public static void main(String[] args) {
        String input = "Hello World Java Example";
        String reversedString = reverseWords(input);
        System.out.println("Original string: " + input);
        System.out.println("Reversed string: " + reversedString);
    }

    public static String reverseWords(String str) {
        String[] words = str.split("\\s+"); // Split the string into words
        StringBuilder reversed = new StringBuilder();
        
        for (int i = words.length - 1; i >= 0; i--) {
            reversed.append(words[i]).append(" "); // Append each word in reverse order
        }
        
        return reversed.toString().trim(); // Trim to remove trailing space
    }
}
