———完成以下游戏角色内容————封装、继承、多态—————————
注:某些方法的形参列表、返回值可以根据情况调整,并非固定不可变
父类:Role(角色),是所有职业的父类
1)属性:name,表示角色的名字
2)方法:public int attack(),该方法返回值为角色的攻击对敌人的伤害
1:Role类
package com.project.game;
public abstract class Role {
private String name;
public Role(){
}
public Role(String name) {
this.name = name;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public abstract int attack();
}
Role的第一个子类:Magicer(法师)
1)属性:魔法等级(范围为1~10)
2)方法:public int attack(),该方法返回法师的攻击对敌人造成的伤害值
法师攻击伤害值为:魔法等级*魔法基本伤害值(固定为5)
2:Magicer类
package com.project.game;
public class Magicer extends Role {
private int magicLevel;
public Magicer() {
}
public Magicer(int magicLevel) {
this.magicLevel = magicLevel;
}
public int getMagicLevel() {
return magicLevel;
}
public void setMagicLevel(int magicLevel) {
this.magicLevel = magicLevel;
}
public int attack(){
int shanghai=5;
int num=magicLevel*shanghai;
System.out.println("法师攻击伤害值为:"+num);
return num;
}
}
Role的第二个子类:Soldier(战士)
1)属性:攻击伤害值
2)方法:public int attack(),该方法返回战士对敌人造成的伤害值
战士的攻击伤害值为:其攻击伤害属性值
3:Soldier类
package com.project.game;
import com.project.game.Role;
public class Soldier extends Role {
private int attackDamage;
public Soldier(){
}
public Soldier(int attackDamage){
this.attackDamage=attackDamage;
}
public int getAttackDamage(){
return attackDamage;
}
public void setAttackDamage(int attackDamage){
this.attackDamage=attackDamage;
}
public int attack(){
System.out.println("战士攻击伤害值为:"+attackDamage);
return attackDamage;
}
}
再设计一个Team类,表示一个组队。
1)addMember,表示组队增加一个成员
注意:组队成员最多为6人
提示:应当利用一个数组属性,保存所有成员
2)attackSum,表示组队所有成员进行攻击时,对敌人造成的总伤害
4:Team类
package com.project.game;
import com.project.game.Magicer;
import com.project.game.Role;
public class Team {
Role[]role;
int count=0;
public void addMember(){
if(count<6){
count++;
role=new Role[count];
}
}
int num=0;
public void addMembers(Role roles){
if(num<role.length){
role[num]=roles;
num++;
}
}
// public void addMembers(Role role1){
// for(int i=1;i<role.length;i++){
// role[i]=role1;
// }
// }
public int attackSum(){
int zongshanghai=0;
for(int i=0;i<role.length;i++){
if(role[i] instanceof Magicer){
zongshanghai+=role[i].attack();
}else{
zongshanghai+=role[i].attack();
}
}
return zongshanghai;
}
}
5:Test测试类
package com.project.game;
import com.project.game.Magicer;
import com.project.game.Soldier;
import com.project.game.Team;
public class Test {
public static void main(String[]args){
Team team=new Team();
team.addMember();
team.addMember();
team.addMember();
team.addMember();
team.addMember();
team.addMember();
System.out.println("count值为:"+team.count);
team.addMembers(new Magicer(2));
team.addMembers(new Magicer(2));
team.addMembers(new Magicer(2));
team.addMembers(new Magicer(2));
team.addMembers(new Magicer(2));
team.addMembers(new Soldier(100));
System.out.println("数组长度为:"+team.role.length);
// for(int i=0;i<team.role.length;i++){
// System.out.println(i+"team.role[i]");
// }
// team.addMembers(new Soldier(10));
// team.addMembers(new Soldier(10));
// team.addMembers(new Soldier(10));
// team.addMembers(new Soldier(10));
// team.addMembers(new Soldier(10));
// team.addMembers(new Soldier(10));
int num=team.attackSum();
System.out.println("总伤害为:"+num);
}
}
—————在上述代码基础之上完成以下需求——封装、继承、多态、接口—————————
创建Role接口,包含两个方法:
1)int attack(); 表示攻击,返回值表示对敌人的伤害
2)void practise(); 表示练习。练习之后对敌人的伤害会增加
6:Role接口
package com.project.gameInterface;
public interface Role {
int attack();
void practise();
}
创建NamedRole类,该类为一个抽象类,实现了Role 接口,并有两个属性:
1)name:角色的名字
2)age:角色的年龄
7:NamedRole抽象类
package com.project.gameInterface;
public abstract class NamedRole implements Role{
private String name;
private int age;
public NamedRole() {
}
public NamedRole(String name, int age) {
this.name = name;
this.age = age;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
}
增加MagicStick接口。该接口表示法师使用的法杖。接口中包含一个方法:
1)int fire()
8:MagicStick接口
package com.project.gameInterface;
public interface MagicStick {
int fire();
}
为MagicStick接口增加两个实现类,分别为GreenStick和BlackStick。其中,对于这两个类的fire方法:
1)GreenStick 平时返回1,夏天(6~8月)使用时返回2
2)BlackStic奇数月返回1,偶数月返回2
9:GreenStick类
package com.project.gameInterface;
import java.time.LocalDate;
import java.time.YearMonth;
public class GreenStick implements MagicStick{
LocalDate currentDate = LocalDate.now();
YearMonth yearMonth = YearMonth.from(currentDate);
int month = yearMonth.getMonthValue();
@Override
public int fire() {
System.out.println("当前月份: " + month);
if(month>=6&&month<=8){
System.out.println("六月到八月返回2");
return 2;
}else {
System.out.println("非六到八月返回1");
return 1;
}
}
}
10:BlackStick类
package com.project.gameInterface;
import java.time.LocalDate;
import java.time.YearMonth;
public class BlackStick implements MagicStick{
LocalDate currentDate = LocalDate.now();
YearMonth yearMonth = YearMonth.from(currentDate);
int month = yearMonth.getMonthValue();
@Override
public int fire() {
System.out.println("当前月份: " + month);
if(month%2==0){
System.out.println("偶数月返回2");
return 2;
}else{
System.out.println("奇数月返回1");
return 1;
}
}
}
修改Magicer类
1)为法师类增加MagicStick类的属性stick,表示法师使用的法杖
2)让其继承自NamedRole类,并实现attack和practise 功能
3)int attack()返回值为法师的魔法等级(level)*每一级的固定伤害(5)
4)void practise()方法:
当法师的stick属性为null时,调用 practise则level++
当法师的stick不为null时,调用practise 方法时,法师的等级level满足:level = level + 1 + stick.fire();即:法师的等级增加为1+stick 属性的fire方法的返回值
11:修改Magicer类
package com.project.gameInterface;
public class Magicer extends NamedRole{
private int magicLevel;
private MagicStick stick;
public Magicer() {
}
public Magicer(int magicLevel,MagicStick stick) {
this.magicLevel = magicLevel;
this.stick=stick;
}
public int getMagicLevel() {
return magicLevel;
}
public void setMagicLevel(int magicLevel) {
this.magicLevel = magicLevel;
}
public MagicStick getStick() {
return stick;
}
public void setStick(MagicStick stick) {
this.stick = stick;
}
public int attack(){
int shanghai=5;
int num=magicLevel*shanghai;
System.out.println("法师攻击伤害值为:"+num);
return num;
}
@Override
public void practise() {
if(stick==null){
magicLevel++;
}else{
magicLevel+=1+stick.fire();
}
System.out.println("法师等级为:"+magicLevel);
}
}
增加Weapon接口,表示战士使用的武器。Weapon接口中定义了两个方法:
1)void setSoldier(Soldier s); 该方法表示设置武器的使用者
2)int fire(); 该方法的返回值表示战士使用该武器时,对敌人的伤害值
12:Weapon接口
package com.project.gameInterface;
public interface Weapon {
//表示战士使用的武器
void setSoldier(Soldier s);
int fire();
}
为 Weapon 增加两个实现了,Bolo,表示大刀,Pike,表示长矛
1)当 soldier 的年龄大于等于 18 岁时,fire 方法返回 100
2)当 soldier 年龄小于 18 岁时,fire 方法返回 50
13:Bole类
package com.project.gameInterface;
public class Bolo implements Weapon{
//大刀实现类
@Override
public void setSoldier(Soldier s) {
if(s.getAge()>=18){
int a=fire();
System.out.println("大于18返回值为"+a);
}else {
int b=fire1();
System.out.println("小于18返回值为"+b);
}
}
@Override
public int fire() {
return 100;
}
public int fire1() {
return 50;
}
}
Pike:Pike 类有一个属性:name,表示长矛的名字
1)当长矛的名字和战士的名字一致时,fire 方法返回 1000
2)当长矛的名字和战士的名字不一致时,fire 方法返回 25
14:Pick类
package com.project.gameInterface;
public class Pick implements Weapon{
//长矛实现类
private String name;
public Pick() {
}
public Pick(String name) {
this.name = name;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
@Override
public void setSoldier(Soldier s) {
if(s.getName().equals(name)){
int a=fire();
System.out.println("名字相等时为:"+a);
}else{
int b=fire1();
System.out.println("名字不相等时为:"+b);
}
}
@Override
public int fire() {
return 1000;
}
public int fire1() {
return 25;
}
// public int fire() {
// if(soldier.getName().equals(name)){
// System.out.println("名字相等时为:"+1000);
// return 1000;
// }else {
// System.out.println("名字不相等时为:"+25);
// return 25;
// }
//
// }
}
修改 Soldier 类
1)为 Soldier 类增加一个 Weapon 属性,表示战士的武器
2)让其继承自 NamedRole 类,并实现 attack 和 practise 功能。其中
Soldier 的 attack() 返回值为战士的 hurt 值与武器的 fire()返回值的 和,即:总攻击输出 = 战士的徒手伤害值 + 武器的伤害值
practise()方法:每调用一次则战士的 hurt 值+10
15:修改Soldirer类
package com.project.gameInterface;
import sun.security.mscapi.SunMSCAPI;
public class Soldier extends NamedRole {
private Weapon weapon;
private String name;
private int age;
private int attackDamage;
public Soldier() {
}
public Soldier(String name) {
this.name = name;
}
public Soldier(int age) {
this.age = age;
}
public Soldier(String name, int age, int attackDamage) {
this.name = name;
this.age = age;
this.attackDamage = attackDamage;
}
public Soldier(Weapon weapon, String name, int age, int attackDamage) {
this.weapon = weapon;
this.name = name;
this.age = age;
this.attackDamage = attackDamage;
}
public Soldier(String name, int age, Weapon weapon, String name1, int age1, int attackDamage, int sum) {
super(name, age);
this.weapon = weapon;
this.name = name1;
this.age = age1;
this.attackDamage = attackDamage;
this.sum = sum;
}
public Weapon getWeapon() {
return weapon;
}
public void setWeapon(Weapon weapon) {
this.weapon = weapon;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public int getAttackDamage() {
return attackDamage;
}
public void setAttackDamage(int attackDamage) {
this.attackDamage = attackDamage;
}
@Override
public void practise() {
attackDamage+=10;
}
int sum=0;
public int attack() {
if (weapon instanceof Bolo){
weapon=new Bolo();
if(age>18){
sum = attackDamage + weapon.fire();
System.out.println("战士攻击伤害值为:" + sum);
}else {
sum = attackDamage + ((Bolo) weapon).fire1();
System.out.println("战士攻击伤害值为:" + sum);
}
return sum;
}else {
weapon=new Pick("张三");
Pick p=(Pick)weapon;
if(p.getName().equals(name)){
sum=attackDamage+weapon.fire();
System.out.println("战士攻击伤害值为:" + sum);
}else {
sum=attackDamage+((Pick) weapon).fire1();
System.out.println("战士攻击伤害值为:" + sum);
}
return sum;
}
}
}
16:测试类Test
package com.project.gameInterface;
public class Test {
public static void main(String[]args){
// BlackStick b=new BlackStick();
// GreenStick g=new GreenStick();
// int num=g.fire();
// System.out.println(num);
// System.out.println(b.fire());
Magicer magicer=new Magicer(10,new BlackStick());
magicer.practise();
Magicer m=new Magicer(10,new GreenStick());
m.practise();
// Magicer mg=new Magicer(10,);
// mg.practise();
System.out.println("_______________________________________");
Weapon b=new Bolo();
b.setSoldier(new Soldier(20));
Weapon pick=new Pick("张三");
pick.setSoldier(new Soldier("张三"));
pick.setSoldier(new Soldier("李四"));
System.out.println("-------------------------------------");
Soldier soldier=new Soldier(new Bolo(),"张三",120,10);
new Bolo().setSoldier(new Soldier(17));
soldier.practise();
soldier.practise();
soldier.practise();
soldier.attack();
new Bolo().setSoldier(new Soldier(20));
soldier.attack();
System.out.println("--------------------------------");
Soldier soldier1=new Soldier(new Pick("张三"),"张三",18,10);
new Pick("李四").setSoldier(new Soldier("张三"));
soldier1.practise();
soldier1.practise();
// new Pick("张三").fire();
soldier1.attack();
Soldier soldier2=new Soldier(new Pick("张三"),"张三",18,10);
new Pick("张三").setSoldier(new Soldier("张三"));
soldier1.attack();
}
}
基本功能已经实现,可能会有部分功能可以编译运行,但是运行结果有误,不会报错
