2. Write a method that takes a String as an input and reverses the String. This reserved result should be the output. code example

Example 1: string reverse in java

String str = "Hello";
String reverse(String str){
  StringBuilder sb = new StringBuilder();
  sb.append(str);
  sb.reverse();
  return sb.toString();
}

Example 2: reverse a string in java

As we know that String is immutable. String class do not have reverse() method.
