java问题求教。 随即产生10个1-1000之间的整数，放在一个数组里，定义方法maxMin（），求出最大值，最小值

Question

要求不鞥使用sort（）方法。
public void maxMin(int [] nums)
详细点啊，才学带参方法，不懂啊- --

Answer 1

/**
* 随机从1-1000产生10个整数放到数组里，返回数组里最大值最小值
* @return 最大值最小值
*/
public int[] maxMin(){
//随机产生10个1-1000的整数放到数组nums中
int nums[] = new int[10];
for(int j=0;j<nums.length;j++){
nums[j] = new Random().nextInt(1000)+1;
System.out.println(nums[j]);
}
//找出数组nums中最大值
int max = 0;
for(int i=0;i<nums.length;i++){
if(max<nums[i]){
max = nums[i];
}
}
int min = 1000;
for(int n=0;n<nums.length;n++){
if(min>nums[n]){
min = nums[n];
}
}
int r[] = new int[2];
r[0] = max;
r[1] = min;
System.out.println(r[0]+"|"+r[1]);
return r;
}

Answer 2

import java.util.Random;
public class MAX_RAD{
/*
生成numb个随机数组
*/
public int[] randArray(int numb){
int[]temp_array=new int[numb];
Random radobj=new Random();
for(int i=0;i<numb;i++){
temp_array[i]=radobj. nextInt(1000)+1;
System.out.println(" i="+ temp_array[i]);
}
return temp_array;
}
/*
发现numb个随机数组中的最大值
*/
public int max_Value(int[]array){
int max=array[0];
for(int i=1;i<array.length;i++){
if(max<array[i]){
max=array[i] ;
}
}
return max;
}
/*
发现numb个随机数组中的最小值
*/
public int min_Value(int[]array){
int min=array[0];
for(int j=1;j<array.length;j++){
if(min>array[j]){
min=array[j] ;
}
}
return min;
}
public static void main(String[]agrs){

MAX_RAD maxclass=new MAX_RAD();
int []test_Array=maxclass.randArray(10);
System.out.println("maxvlue="+maxclass.max_Value(test_Array));
System.out.println("minvlue="+maxclass.min_Value(test_Array));
}

}
算法的效率为n
