   • An instance variable named score of type integer.
   • A constructor that accepts an integer parameter, whose value is used to initialize the score instance variable.
   • A method named addScores that accepts a variable-length parameter list of int named scores and returns the total score of the score instance variable plus the scores in the variable length paremeter list named scores.
   • A method named bonusPoints that accepts an integer parameter. The value of score is increased by the value of the parameter.
   • A toString method that returns the string of a ScoreBoard object.

import java.io.*;
import java.lang.*;
class Scoreboard
{
   public static int score,totalScore=0; //variable static declared for using static methods
   String str;
   Scoreboard(int num) //constructor initailize score variable
   {
       score = num;
   }
   public static void bonusPoints(int bonus) //bonnus points method that assepts an integer
   {
       score = score+ bonus; //increase the value of score variable
   }
  
   public static int addScores(int scores) //addScore method to add score and return total
   {
       totalScore = scores*score;
       return totalScore;
      
      
   }
  
public static void main(String[]args) //main method
{
   Scoreboard str = new Scoreboard(20); //call constructor
   str.bonusPoints(10); //call method
   System.out.println(str.addScores(5)); //returninh object compiler will write here str.toString() here
}
