Program to reverse a string in java

Reverse a String in java Explanation : pseudo Code

1. Convert the string to array of characters.
2. add all the characters to the stack
3. create an object of the StringBuilder class and keep on adding the stack characters to the StringBuilder object.
4. convert string builder to the string.

 public static String reverseString(String word) {
        Stack<Character> charStack = new Stack<>();
        for (char ch : word.toCharArray()) {
            charStack.push(ch);
        }
        StringBuilder sbString = new StringBuilder();
        while (!charStack.isEmpty()) {
            sbString.append(charStack.pop());
        }
        return sbString.toString();
    }

StringBuilder has a reverse method you could utilize, since you're already using StringBuilder.

StringBuilder input = new StringBuilder();
input.append(input);
input.reverse();

stringBuilder reverse would also loop on the elements on the stack. i used string builder to not create many string pools in the java.
