Modify the program below to create a class that contains a static method; the method takes a string as a parameter and returns a boolean value indicating whether the parameter string has repeated characters in it or not. That is, return true if there is at least one character which appears more than once in the string. The string should be input by the .user import java .util.*; public class Main{public static void main(String args[]){Scanner scn=new Scanner(System.in); // Input the string from userSystem.out.println ( "Enter the String to check for duplicate characters:");String str = scn.next();// Check is variable to store bool value true// It will change to true if there are repeated charactersboolean check=false;for (int a = 0; a < str.length(); a++)for (int b = a + 1; b < str.length(); b++)if (str.charAt(a) == str.charAt(b))check=true;// If check is true then string has repeated characters if (check)System.out.println("The String " + str + " has repeated…

This method simulates the playing of one round of “Rock Paper Scissors”. In this strange version of the game, if both players have the same hand gestures, the return value is 1. If they have different hand gestures, the return value is a 0. If at least one player, provides a string argument that is anything other than rock, paper, or scissors, the return value is -1. The method should not be case-sensitive. For example, rock, ROCK, Rock, and RocK are all valid. The output is in the image I added
