Java开发中经典的小实例-(随机数)

import java.util.Random;

//输出小于33的7个不相同的随机数
public class probability {

static Random random = new Random();

static int[] array = new int[7];

static int number;

public static void main(String[] args) {
        // TODO Auto-generated method stub

for (int i = 0; i < array.length - 1; i++) {
            number = (random.nextInt(33)) + 1;

if (i != 0) {

while (isRepeat(i, number)) {

number = random.nextInt(33) + 1;
                }

}

array[i] = number;

}
        array[6] = (int) (Math.random() * 16) + 1;

for (int j : array) {

System.out.println(j);
        }

}

public static boolean isRepeat(int size, int number) {

boolean reqeat = false;

for (int i = 0; i < size; i++) {

if (array[i] == number) {

reqeat = true;
                break;
            }

}

return reqeat;

}
