java中Random的用法

import java.util.Random;public class MathOperators {/** * @param args */public static void main(String[] args) {// TODO Auto-generated method stub//随机数的产生int[] arr = new int[10];Random r = new Random();for (int m = 0; m < arr.length; m++){arr[m] = r.nextInt(100);}for (int n = 0; n < arr.length; n++){System.out.println(arr[n]);} }}
