产生10个随机数放入数组，不允许有重复

Posted 2023-02-06 心忘则忘

import java.util.Arrays;


public class Random
public static void main(String[] args)
int a[] = new int[10];
a[0] = (int) (Math.random() * 10 + 1);
outer: for (int i = 1; i < 10; i++)
int t = (int) (Math.random() * 10 + 1);
for (int j = 0; j < 10; j++)
if (t == a[j])
i--;
continue outer;
 

a[i]=t;

        System.out.println(Arrays.toString(a));
