Go4Expert - Football simulator help!!!!!!

This is what I have so far:

Code:

import java.io.* ;



class Tut2 {

     public static void main(String args[])

    

     {

          InputStreamReader istream = new InputStreamReader(System.in) ;

          BufferedReader bufRead = new BufferedReader(istream) ;



          System.out.println("Welcome To My First Java Program");



          try {

               System.out.println("Please Enter Higher Ranked Team ");

               String firstName = bufRead.readLine();



               System.out.println("Please Enter Lower Ranked Team ");

               String bornYear = bufRead.readLine();



               System.out.println("Please Enter Rank of Higher Ranked Team ");

               String higher = bufRead.readLine();

               

               System.out.println("Please Enter Rank of Lower Ranked Team ");

               String lower = bufRead.readLine();



               int low = Integer.parseInt(lower);

               int high = Integer.parseInt(higher);

               float num1 = .84f;



               int x = low - high;

               

               float t = x * num1;

               

               float m = 100f - t;

               

            System.out.println("Percentage "+ firstName +" wins is " + t + "%");

            System.out.println("Percentage "+ bornYear +" wins is " + m + "%");

          }

          catch (IOException err) {

               System.out.println("Error reading line");

          }

          catch(NumberFormatException err) {

               System.out.println("Error Converting Number");

          }   

     }

}

I need it to recognize "m" and "t" as percentages and then based off of the those pick one of them. I know how to show the winner I just need to know how to get the program to pick the winner or if it is possible to do this.
