Q3: java-----输入5种水果的英文名称，按照第一个字母排序后输出
具体代码如下，你建一个名为Test.java的文件，将以下代码复制，编译运行即可。
import java.util.Scanner;
public class Test {
public static void main(String [] args)
{
System.out.println("====程序开始执行!====");
while(true)
{
System.out.println("请输入五种水果的名字，中间用逗号隔开:");
Scanner r=new Scanner(System.in);
//接收用户输入
String str=r.next();
//定义正则表达式来检验用户输入格式是否合法
String regex="[a-zA-Z]+,[a-zA-Z]+,[a-zA-Z]+,[a-zA-Z]+,[a-zA-Z]+";
if(!str.matches(regex))
{
System.out.println("您输入的格式不合法，请重新输入");
continue;
}
try
{
System.out.println("您输入的序列为:["+str+"],重新输入请按1,进行排序请按2,退出请按其它任意键");
int flag=r.nextInt();
switch(flag)
{
//提示用户重新输入
case 1:
{
continue;
}
//按第一个字母排序并输出
case 2:
{
String [] tmp=str.split(",");
int length=tmp.length;
//由于只有五种水果,不涉及效率问题,用冒泡排序即可
for(int i=0;ilength-1;i++)
{
for(int j=0;jlength-i-1;j++)
{
if(tmp[j].compareTo(tmp[j+1])0)
{
String strtmp=tmp[j];
tmp[j]=tmp[j+1];
tmp[j+1]=strtmp;
}
}
}
System.out.println("按任意键正序输出排序后结果,如想逆序输出请按n");
String outflag=r.next();
if(outflag.equals("n"))
{
System.out.print("逆序结果为:");
for(int k=length-1;k=0;k--)
{
System.out.print("["+tmp[k]+"]");
}
System.out.println("");
}
else
{
System.out.print("正序结果为:");
for(int k=0;klength;k++)
{
System.out.print("["+tmp[k]+"]");
}
System.out.println("");
}
}
}
//程序执行完毕,退出while循环
break;
}
catch(Exception e)
{
//出现异常 说明用户输入了非数字键,此时退出程序
break;
}
}
System.out.println("====程序执行结束!====");
}

Q4: 用JAVA编写水果摊销售管理,销售3种水果,
没有用编译工具 可以能语法错误 自己去 eclipse调整 我给水果管理系统JAVA代码你水果管理系统JAVA代码的是思路
抽象类 abstract Fruit 属性 --重量 单价
子类 ---水果1
子类 ---水果2
子类 ---水果3
public float getPrice(Fruit fruit,String sex){
Float total ;
if(fruit.instanceof(水果1)){
total = fruit.get重量（）*fruit.get单价（）；
if(sex.equals("女")){
total = total*0.8;
}
}
if(fruit.instanceof(水果2)){
total = fruit.get重量（）*fruit.get单价（）；
if(sex.equals("女")){
total = total*0.8;
}
}
if(fruit.instanceof(水果3)){
total = fruit.get重量（）*fruit.get单价（）；
if(sex.equals("女")){
total = total*0.8;
}
}
return total ;
}
Q5: java数组添加元素
case 4的代码有些逻辑问题水果管理系统JAVA代码，其实已经添加成功水果管理系统JAVA代码了，只不过水果管理系统JAVA代码你对 fruit 进行循环，导致循环了5次，每次循环都要添加一次。
正确的做法是，先找出空位置，记录下这个空位置的索引，然后再添加，更改后的 case 4 如下代码：
case 4:// 添加水果
int pos = -1;
// 先找到一个空位
for (int i = 0; i fruit.length; i++) {
if (fruit[i] == null) {
pos = i;
}
}
// 如果 pos != -1 说明有空位，否则没有位置添加新水果
if (pos != -1) {
System.out.println("请输入要添加的水果：");
String name = input.next();
fruit[pos] = name;
} else {
System.out.println("没有位置添加水果！");
}
break;
