编写一个java程序，输入一组整数，以－1结束，比较并输出其中的最大值和最小值

Answer 1

package collection;

import java.util.ArrayList;
import java.util.Arrays;
import java.util.Iterator;
import java.util.List;
import java.util.Scanner;

public class TestSort {

public static void main(String[] args) {
System.out.println("输入一组数字,以空格分隔,以-1结束");
Scanner sc = new Scanner(System.in);
int n;
List list = new ArrayList();
while ((n = sc.nextInt()) != -1) {
list.add(n);
}
Object array[] = list.toArray();
Arrays.sort(array);
list = Arrays.asList(array);

System.out.println("max" + list.get(list.size() - 1));
System.out.println("min" + list.get(0));
}

}

Answer 2

import java.util.Scanner;
public class test{
public static void main(String dsfa[]){
Scanner sc=new Scanner(System.in);
int max;
int min;
int p;
p=sc.nextInt();
if(p==-1){
System.out.println("没有任何数据输入");
}
max=p;
min=p;
while(p!=-1){
if(max<p)max=p;
if(min>p)min=p;
p=sc.nextInt();
}
System.out.println("输入的最大值是:"+max+" 最小值是:"+min);
}
}
