I can't get my winning to not be zero. And I don't see why.

import java.util.*;

      int loop = 1;
      int winnings =0 ;

      GetPayMultiplier(s1,s2,s3);
      Display(s1,s2,s3,winnings);
      }
      
   }

      System.out.print("Please enter your bet from 1 - 100 here," +
      " or 0 to close : ");
      Bet = input.nextInt();

      while(Bet > 100)
      {

You can't use == and != to test whether two Strings have the same sequence of letters. The == and != test whether they are exactly the same Object.
Th test you need to use is the equals method...
string1.equals(string2)
