1、使用封裝實現電子寵物系統的企鵝類正確輸入健康值和親密度

• 保證健康值的有效性0~100，否則取默認值60
• 保證親密度的有效性0~100，否則取默認值60

輸出結果如下：

歡迎來到寵物店！

領養寵物的名字： 豆豆

寵物類型：1、狗狗 2、 企鵝 2

企鵝的性別： 1. Q仔 2.Q妹 1

企鵝健康值0~100之間： -7

健康值應該在0到100之間，默認值為60

寵物的獨白：

我的名字叫豆豆，健康值為60，和主人的親密度是0，我的性別是 Q仔。

實現結果如下：

import org.omg.CORBA.PUBLIC_MEMBER;public class Pet {private int love; //親密度private int health; //健康值private String name;private int age;public void setlove(int love) {if (love<0 || love>100) {System.out.println("親密值是："+love);this.love=60; //默認值}else {this.love=love;} } public int getlove() {return love; } public void setHealth(int health) {if (health<0 || health>100) {System.out.println("健康值是："+health);this.health=60;}else {this.health=health;}} public int getHealth() {return health; } public void setName(String name) {this.name=name; } public String getName() {return name; } public void setAge(int age) {this.age =age; } public int getAge() {return age; } }

測試

import java.util.Scanner;public class TestPet {public static void main(String[] args) {//String name;String sex = null;//int age,love,health;System.out.println("歡迎來到寵物店！");Pet pet =new Pet();pet.setName("豆豆");pet.getName();Scanner sa =new Scanner(System.in);System.out.println("請選擇要選擇的寵物類型 1、狗 2、企鵝");String num =sa.next();if (num.equals("1")) {System.out.println("請選擇狗狗的性別 1.Q仔 2.Q妹");}else {System.out.println("請選擇企鵝的性別 1.Q仔 2.Q妹");}int num1=sa.nextInt();switch(num1) {case 1:sex = "Q仔";break;case 2:sex = "Q妹";break;}System.out.println("請輸入狗狗的健康值1~100之間");int num3=sa.nextInt();if (num3<0 || num3>100) {System.out.println("健康值應該在0~100之間，默認值60");}else {System.out.println("健康值為："+num3);}pet.setAge(8);pet.getAge();pet.setHealth(60);pet.getHealth();System.out.println("寵物的獨白：");System.out.println("我的名字叫"+pet.getName()+",健康值是"+pet.getHealth()+",今年已經"+pet.getAge()+"歲。和主人的親密是"+pet.getlove()+",我的性別是"+sex);}}

2、定義一個簡單的計算機

要求：

輸入兩位數時，兩個數相加

輸入三個數時，三個數求平均數

輸入四個數時，求積

實現結果如下：

public class Jisuanji {int sum; //和double avg; //平均數int product; // 積private int a;private int b;private int c;private int d;public Jisuanji() {}public Jisuanji(int a, int b, int c, int d) {this.a = a;this.b =b;this.c =c;this.d =d;}public void show() {sum =a+b;avg = (a+b+c)/3;product=a*b*c*d;System.out.println("和是："+sum);System.out.println("平均數是："+avg);System.out.println("積是："+product); } }

測試

public class DomeJisuanji {public static void main(String[] args) {Jisuanji jsj = new Jisuanji(15,10,2,5);jsj.show();} }

使用重載方法如下：

public class SuanTi {int sum; //和double avg; //平均數int product; //積public SuanTi() {}public int SuanTi(int a, int b) {sum=a+b;return sum;}public void showSum() {System.out.println("和是："+sum); }public double SuanTi(int a, int b, int c) {avg=(a+b+c)/3;return avg; }public void showAvg() {System.out.println("平均數是："+avg); }public int SuanTi(int a, int b, int c,int d) {product=a*b*c*d;return product;}public void showProduct() {System.out.println("積是："+product); } }

使用Scanner 輸入接收

import java.util.Scanner;public class DomeSuanTi {public static void main(String[] args) {Scanner sa = new Scanner(System.in);System.out.println("輸入a：");int a =sa.nextInt();System.out.println("輸入b：");int b =sa.nextInt();System.out.println("輸入c：");int c =sa.nextInt();System.out.println("輸入d：");int d =sa.nextInt();SuanTi st = new SuanTi();st.SuanTi(a,b);st.showSum();st.SuanTi( a, b, c);st.showAvg();st.SuanTi(a, b, c, d);st.showProduct();} }

3、景區門票系統：

名字+年齡

名字為 n 時，退出程序！

年齡大于60或小于15的免費，否則門票 20元

實現結果如下：

import java.util.Scanner;public class Visitor {String name;int age; public void show() {Scanner sa =new Scanner(System.in);while (!"n".equals(name)) {if (age>60 || age<18) {System.out.println(name+"的年齡是："+age+"\t門票免費");}else {System.out.println(name+"的年齡是："+age+"\t門票20元·\n");}System.out.println("請輸入姓名：");name=sa.next();if (!"n".equals(name)) {System.out.println("請輸入年齡：");age=sa.nextInt();}}System.out.println("退出程序！"); } }

測試

import java.util.Scanner;public class DomeVisitor {public static void main(String[] args) {Visitor visitor = new Visitor();Scanner sa =new Scanner(System.in);System.out.println("請輸入姓名：");visitor.name=sa.next();System.out.println("請輸入年齡：");visitor.age = sa.nextInt();visitor.show();} }

4、使用面向對象new 一個女朋友出來， 哈哈

話不多說，走起！

創建屬性；

創建方法；

public class GirlFriend {private String name; //名字private char sex; //性別private int age; //年齡private String look; //相貌private double height; //身高private double weight; //體重private String hairdo; //發型private String ethos; //氣質private String character; //性格private String dress; //穿衣 public void setName(String name) {/** 設置姓名*/this.name = name; } public String getName() {//獲取名字return name; }public void setAge(int age) {this.age = age;//設置年齡 } public int getAge() {return age; //獲取年齡} public void setSex(char sex) {this.sex = sex; } public char getSex() {return sex; } public void setLook(String look) {this.look =look; } public String getLook() {return look; } public void setHeight(double height) {this.height =height; } public double getHeight() {return height; } public void setWeight(double weight) {this.weight =weight; } public double getWeight() {return weight; } public void setHairdo(String hairdo) {this.hairdo =hairdo; } public String getHairdo() {return hairdo; } public void setEthos(String ethos) {this.ethos =ethos; //設置氣質 } public String getEthos() {return ethos; //獲取氣質 } public void setCharacter(String character) {this.character =character; } public String getCharacter() {return character; } public void setDress(String dress) {this.dress =dress; } public String getDress() {return dress; } public void playGame() {// 打游戲System.out.println(name+"打游戲很厲害"); } public void coqutry() {//撒嬌System.out.println("不要不要嘛，就要你抱抱"); } public void speak() {// 說話System.out.println("今天的你太迷人了，愛你，愛你，愛你！"); } public void dance() {//跳舞System.out.println("性感女團舞，身材曼妙"); } public void cute() {//賣萌System.out.println("嘟嘟嘴，你好壞，你好壞！"); } public void eat() {//做飯System.out.println("紅燒羊排，涼拌牛雜，麻辣小龍蝦，烤腰子，西湖牛肉羹，五常米飯"); } }

開始實現測試

import java.util.Scanner;public class DomeGirlFriend {public static void main(String[] args) {Scanner sa = new Scanner(System.in);String name,look,character,dress;String hairdo,ethos;double height,weight;int age;char sex;GirlFriend girl = new GirlFriend();girl.setName("趙歡");name = girl.getName();girl.setSex('女');sex=girl.getSex();girl.setAge(28);age =girl.getAge();girl.setHeight(165.7);height =girl.getHeight();girl.setLook("膚白貌美，S型身材");look =girl.getLook();girl.setWeight(51.38);weight =girl.getWeight();girl.setEthos("清純性感");ethos = girl.getEthos();girl.setHairdo("過肩直發");hairdo = girl.getHairdo();girl.setCharacter("溫柔，善解人意");character =girl.getCharacter();girl.setDress("露臍裝，緊身牛仔褲，白色運動鞋");dress =girl.getDress();System.out.println("女朋友簡介：\n輸入指令 0 退出");System.out.println(name+"是一個"+hairdo+"的"+sex+"人，她的長相"+look+"，性格"+character);System.out.println();System.out.println("她身高"+height+";體重"+weight+";今年"+age+"歲了。身穿"+dress+"，氣質這塊顯得"+ethos);while(true) {System.out.println("主人，你需要我做什么服務：");String a = sa.next();switch (a) {case "打游戲":girl.playGame();break;case "撒嬌":girl.coqutry();break;case "賣萌":girl.cute();break;case "跳舞":girl.dance();break;case "吃飯":girl.eat();break;case "0":System.out.println("再見了，寶貝");break;}if ("0".equals(a)) {break;}}}}

好了，根據你們的愛好自由發揮哈！
