title: Variable shows but I don't want it to show
body: <p>I'm making code for a Blackjack game. </p>
  
  <p>I've already made the necessary switch statements to generate a random card and have set a variable to them so I don't have to keep copying and pasting. </p>
  
  <p>My problem is that whenever I press run, it shows a zero and then the generated card. I know this is because I've set playerCard1 to zero, but I dunno how to get rid of it. </p>
  
  <p>Here's my code if it's any help</p>
  
  <pre><code>public class var {
  
      public static void main(String[] args) {
  
          int playerCard1 = 0;
          int suit = 0;
          char suitChar = ' ';
          int num = playerCard1;
  
          //making playerCard1 generate a random number between 1 and 13
          playerCard1 = (int)(Math.random() * 13 + 1);
  
          //making suit generate a random number between 1 and 4 for first card
          suit = (int)(Math.random() * 4 + 1);
  
          System.out.println(num);
  
          //switch statements for suit of player's first card
  
          switch (suit){
              case 1: suitChar = 'D'; //diamonds
                  break;
  
              case 2: suitChar = 'S'; //spades
                  break;
  
              case 3: suitChar = 'H'; //hearts
                  break;
  
              case 4: suitChar = 'C'; //clubs
                  break;
  
  
          }//end of switch statements for suit of player's first card 
          switch (playerCard1){
          case 1: System.out.print("A" + suitChar);
              break;
  
          case 2: System.out.print("2" + suitChar );
              break;
  
          case 3: System.out.print("3" + suitChar);
          break;
  
          case 4: System.out.print("4" + suitChar );
              break;
  
          case 5: System.out.print("5" + suitChar );
              break;
  
          case 6: System.out.print("6" + suitChar );
              break;
  
          case 7: System.out.print("7" + suitChar);
              break;
  
          case 8: System.out.print("8" + suitChar );
              break;
  
          case 9: System.out.print("9" + suitChar);
              break;
  
          case 10: System.out.print("10" + suitChar );
              break;
  
          case 11: System.out.print("J" + suitChar );

          case 13: System.out.print("K" + suitChar);
              break;
  
  
              }//end of switch statements for playerCard1
  
  
      }//end of main
  
  }//end of class
