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

java 复制代码

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

java 复制代码

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