要求：随机产生10个1-1000之间的整数，放在一个数组中，方法定义maxMin();求出其中的最大值和最小值，要求不能使用sort()放法。
提示：产生随机参数的代码：Math.random()*1000;
定义方法maxMin():
public void maxMin(int [] nums){......}
写出方法类和测试类！
------解决方案--------------------------------------------------------
你把你考试的代码弄上来嗦，大不了就一个排序，最简单的冒泡总会嘛，要的到一个数组for循环10次Math.random()*1000;不就有了

- Java code
public class Demo { public static void main(String[] args) { int[] nums = new int[10]; for(int i = 0; i < 10; i++) { nums[i] = (int) (Math.random() * 999) + 1; } Demo demo = new Demo(); demo.maxMin(nums); for(int i : nums) { System.out.print(i + "\t"); } } public void maxMin(int[] nums) { int max = nums[0]; int min = nums[0]; for(int i : nums) { if(max < i) { max = i; } if(min > i) { min = i; } } System.out.println("最大致为：" + max + ",最小值为:" + min + "."); }}
