JAVA1027抽象类；抽象类继承

依赖string特性？是否
​​核心特性​​：不可变性（创建后内容不可修改）

JAVA字符串类型
char[] (字符数组)

抽象类

public abstract class Player {public void PlayGenShin(){System.out.println("I like to play yuanshen");}class War3Player{private char[] Name;War3Player(char Name){this.Name=new char[Name];}private Integer num;War3Player(Integer num){this.num=new Integer(num);}}//int 是整形，开辟一个空间 命名，应该用字符串类型：char String等//int是基本类型，没有构造方法，要用integer//定义变量需要用驼峰命名法吗？public abstract void PlayLol();public void PlayGame(){PlayGenShin();War3Player xiaocao=new War3Player('k');War3Player playwar3=new War3Player(3);}public void main(String[] args){System.out.println("yuanshen qidong");}
}

抽象类继承

public class PlayerExtend extends Player{@Overridepublic void PlayLol() {
PlayerExtend ok=new PlayerExtend();
ok.PlayGenShin();
ok.main(null);}
}
