【程序34】

题目：输入3个数a,b,c，按大小顺序输出。

import java.util.Scanner;

public class lianxi34 {

public static void main(String[] args) {

Scanner s = new Scanner(System.in);

System.out.println("请输入3个整数：");

int a = s.nextInt();

int b = s.nextInt();

int c = s.nextInt();

if(a < b) {

int t = a;

a = b;

b = t;

}

if(a < c) {

int t = a;

a = c;

c = t;

}

if(b < c) {

int t = b;

b = c;

c = t;

}

System.out.println("从大到小的顺序输出:");

System.out.println(a + " " + b + " " + c);

}

}

【程序35】

题目：输入数组，最大的与第一个元素交换，最小的与最后一个元素交换，输出数组。 import java.util.*;

public class lianxi35 {

public static void main(String[] args) {

int N = 8;

int[] a = new int [N];

Scanner s = new Scanner(System.in);

int idx1 = 0, idx2 = 0;

System.out.println("请输入8个整数：");

for(int i=0; i<N; i++) {

a[i] = s.nextInt();

}

System.out.println("你输入的数组为：");
