如何编辑我的代码以包含方法

Question

如何编辑我的代码以包含方法，将其命名为rollDice（），以返回1到6之间生成的随机整数？感谢。

这是我目前的代码：

public class CrapsGame {

  public static void main(String[] args) {
      int dice1 = (int)(Math.random()* 6) + 1;
      int dice2 = (int)(Math.random()* 6) + 1;
      int roll = dice1 + dice2;
      System.out.println();
      System.out.print("You rolled "+roll+". ");
      if(roll == 2 || roll == 3 || roll == 12){
         System.out.println("You lose");
      }
      else if(roll == 7 || roll == 11){
          System.out.println("You win");
      }
       else{
         System.out.println("point is "+roll+"\n");
         dice1 = (int)(Math.random()* 6) + 1;
         dice2 = (int)(Math.random()* 6) + 1;
         int roll2 = dice1 + dice2;
         System.out.print("You rolled "+roll2+". ");
         while(roll2 != 7){
            if(roll == roll2){
               System.out.println("You win");
               break;
            }
            else{
               System.out.println("point is "+roll+"\n");
            }
            dice1 = (int)(Math.random()* 6) + 1;
            dice2 = (int)(Math.random()* 6) + 1;
            roll2 = dice1 + dice2;
            System.out.print("You rolled "+roll2+". ");
         }
         if(roll2 == 7){
             System.out.println("You lose");
         }          
      }
   }
}

public class CrapsGame {

  public static void main(String[] args) {
      int dice1 = rollDice();
      (...)
   }

   private static int rollDice() {
      return (int)(Math.random()* 6) + 1;
   }
}
