Create a java program that has three version of add method which can add two, three, and four integers

class VersionAddition

    {

      void firstVersion()

        {

          System.out.println("Enter the two no.s->");

          int a=Integer.parseInt(System.console().readLine("enter the valye fo first no. ="));

          int b=Integer.parseInt(System.console().readLine("enter the valye fo second no.="));

          int sum=a+b;

          System.out.println("sum of two integer ="+sum);

        }

       void secondVersion()

        {

          System.out.println(" ");

          System.out.println("Enter the three no.s->");

          int c=Integer.parseInt(System.console().readLine("enter the valye fo first no. ="));

          int d=Integer.parseInt(System.console().readLine("enter the valye fo second no.="));

          int e=Integer.parseInt(System.console().readLine("enter the valye fo third  no.="));

          int sum=c+d+e;

          System.out.println("sum of three integer ="+sum);

        }

       void thirdVersion()

        {

          System.out.println(" ");

          System.out.println("Enter the four no.s->");

          int f=Integer.parseInt(System.console().readLine("enter the valye fo first no. ="));

          int g=Integer.parseInt(System.console().readLine("enter the valye fo second no.="));

          int h=Integer.parseInt(System.console().readLine("enter the valye fo third  no.="));

          int i=Integer.parseInt(System.console().readLine("enter the valye fo forth  no.="));

          int sum=f+g+h+i;

          System.out.println("sum of four integer ="+sum);

        }

   public static void main(String args[])

      {

        VersionAddition v=new VersionAddition();

        v.firstVersion();

        v.secondVersion();

        v.thirdVersion();

      }

  }
