递归实现随机数不重复问题

public class Random {

public static int[] randoms = new int[5];

public static void main(String[] args) {
for (int i = 0; i < 5; i++) {
randoms[i] = getRandom();
System.out.print(randoms[i] + "|");
}
}

// 获取单个随机数
static int random =0;
public static int getRandom() {
random= (int) (Math.random() * 5 + 1);
for (int j = 0; j < randoms.length; j++) {
if (random == randoms[j]) {
getRandom();
}
}
return random;
}
}
