明明有打印的语句 但是运行起来时没有打印出来 你们复制粘贴运行一下看会不会这样

System.out.println("出现6的概率"+sixodds);
}

   public static void main(String[] args) {
       getNumber(100);
   }

}

Answer 1

这样就可以了

public class A {
    public static void main(String[] args) {
        getNumber(100);
    }

    public static void getNumber(double times) {
        double i = 1;
        int onetimes = 0;
        int twotimes = 0;
        int threetimes = 0;
        int fourtimes = 0;
        int fivetimes = 0;
        int sixtimes = 0;
        while (i <= times) {
            int target = (int) (Math.random() * 10 / 1);
            if (target >= 1 && target <= 6) {
                switch (target) {
                    case (1):
                        onetimes++;
                        break;
                    case (2):
                        twotimes++;
                        break;
                    case (3):
                        threetimes++;
                        break;
                    case (4):
                        fourtimes++;
                        break;
                    case (5):
                        fivetimes++;
                        break;
                    case (6):
                        sixtimes++;
                        break;
                    default:
                        break;
                }
                i ++;
            }
        }
        double oneodds = onetimes / i;
        double twoodds = twotimes / i;
        double threeodds = threetimes / i;
        double fourodds = fourtimes / i;
        double fiveodds = fivetimes / i;
        double sixodds = sixtimes / i;
        System.out.println("出现1的概率" + oneodds);
        System.out.println("出现2的概率" + twoodds);
        System.out.println("出现3的概率" + threeodds);
        System.out.println("出现4的概率" + fourodds);
        System.out.println("出现5的概率" + fiveodds);
        System.out.println("出现6的概率" + sixodds);
    }
