为什么我的程序不知道敌人和英雄对象存在？ [等候接听]
[英]Why doesnt my program know that enemy and Hero object exist? [on hold]
问题描述
我正在从事地下城爬行游戏。 要求之一是使Character和Enemy类从一个公共基类派生类（或实现一个公共接口）。 该基类将包含两者的共同点，例如位置，能够移动并具有某种在屏幕上显示的方式。 我通过创建一个角色类来做到这一点，该角色类是敌人和英雄的父类。 在执行继承要求之前，我的玩家可以移动并做所有事情，现在它什么也没做，只是跳到成功消息。 我怎样才能解决这个问题？ 在底部，我将只发布一半的代码，请告诉我是否正确进行了继承。 如果没有，我该如何解决。
人物类代码：
abstract class Character{
private String name;
private int health;
public Character(String name, int health){
this.name = name;
this.health = health;
}
public abstract void damage(int hit);
public abstract String getname();
public abstract boolean isAlive();
public abstract void girlTaunt();
public abstract void boyTaunt();
}
敌人的代码：
import java.util.*;
class Enemy extends Character {
String name;
int health;
Item weapon;
public Enemy(String name, int health, Item Weapon) {
super(name, health);
this.weapon = Weapon;
}
public int health(){
return this.health;
}
public boolean isAlive() {
if (this.health <= 0) {
return false;
}
return true;
}
public void damage(int hit){
this.health -= hit;
}
public int power(){
return this.weapon.getPower();
//return health - damage;
}
public String equippedWeapon(){
return this.weapon.toString();
}//ending bracket for equip
public void girlTaunt(){
Random rand = new Random();
int i = rand.nextInt()%3;
switch (i){
case 0:
System.out.println("ARI: ahhh booo wahh wahhh I don't know what to do!!");
break;
case 1:
System.out.println("ARI: i'll fake a pregnancy test...!");
break;
case 2:
System.out.println("ARI: I will CONSENSUALLY beat the cashews out of you.");
break;
default:
break;
}
}//end of girlTaunt
public void boyTaunt(){
Random rand = new Random();
int i = rand.nextInt()%3;
switch (i){
case 0:
System.out.println("GARRET: Oh no why don't you love me???????");
break;
case 1:
System.out.println("GARRET: You better watch yourself, i'll threaten you with a marriage propsal!!");
break;
case 2:
System.out.println( "GARRET: If I beat you up, my wife's boyfriend said that he'll buy me a nintendo switch");
break;
default:
break;
}
System.out.println(" ");
}
public String getname(){
return name;
}
}
英雄等级：
import java.util.Scanner;
import java.io.PrintWriter;
class Hero extends Character{
public int health;
public boolean isalive;
private String name;
private String Class;
Hero(String name, int health, String Class){

this.Class = Class;
this.health = 100;
this.isalive = true;
}
public String getname(){
return name;
}
void save(PrintWriter pw){
pw.println(name);
// Hero.save(pw);
}
public void damage(int hit){

}
public boolean isAlive(){// Check my parameters and the code in the method.
if(this.health > 0){
return true;

}
public void girlTaunt(){
System.out.println(this.name + ":YOU'RE SO BOGUS! YOU SHOULD BE LIKE ME, A STRONG INDEPDENT SEXY MAN");
}
public void boyTaunt(){
System.out.println(this.name + "I am SO glad I dumped you. Whew. Dodged a bullet with that one!");

请告诉我我继承权是否正确
你没有
您在基类中有私有变量name和health ，没有getter或setter。 然后，在子类中声明了具有相同名称的变量。
这些是不同的变量。
另外，变量的可见性不一致。 在某些情况下，它们是private ，在其他情况下则是私有的，而其他则是public 。
你需要：
- 摆脱实例变量
- 将它们全部声明为
private - 根据需要声明（
public或projected）吸气剂和吸气剂。 - 使用getter和setter访问cchild类中的私有变量。
目前尚不清楚这是否可以解决您的所有问题，但这只是一个开始。
