解题思路:

注意事项:

参考代码:

import java.util.ArrayList;

import java.util.Collections;

import java.util.List;

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

List<Integer> list = new ArrayList<>();

Scanner in = new Scanner(System.in);

for (int a = 0; a < 10; a++) {

list.add(in.nextInt());

}

int m = list.get(0);

int locate = 0;

//找到最小值

for(int a = 1;a < 10;a ++){

if(m>list.get(a)){

m=list.get(a);

locate=a;

}

}

//交换

int tem;

tem = list.get(0);

list.set(0, m);

list.set(locate, tem);

//找到最大值

m = list.get(0);

locate = 0;

for(int a = 1;a < 10;a ++){

if(m<list.get(a)){

m=list.get(a);

locate=a;

}

}

tem = list.get(9);

list.set(9, m);

list.set(locate, tem);

for(int a = 0;a < 10;a ++){

System.out.print(list.get(a)+" ");

}

}

}
