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]); } } }
