产生m个n以内的随机数

public class Test{
public static void main(String[] args) {
Scanner scanner1 = new Scanner(System.in);
System.out.println("请输入您想产生多大数以内的随机数：");
int n = scanner1.nextInt();
Scanner scanner2 = new Scanner(System.in);
System.out.println("请输入您想产生多少个随机数：");
int m = scanner2.nextInt();
random(n,m);
}

public static void random(int n,int m){
Random random = new Random();
int[] arr = new int[m];
for(int i=0;i<m;i++){
arr[i] = random.nextInt(n);
}
System.out.println("结果如下：");
for(Integer e:arr){
System.out.print(e + " ");
}
}
