本文通过创建英雄角色和武器类，演示了Java面向对象编程的基本概念，包括类、对象、属性和方法。英雄类包含名称、武器和年龄属性，并实现攻击行为。武器类则负责定义武器的代码。

    package neibulei.Demo6;   //独立文件
    
    public class Hero {
        private String name;
        private Weapon weapon;
        private int age;
    
        public Hero() {
        }
    
        public Hero(String name, Weapon weapon, int age) {
            this.name = name;
            this.weapon = weapon;
            this.age = age;
        }
    
        public String getName() {
            return name;
        }
    
        public void setName(String name) {
            this.name = name;
        }
    
        public Weapon getWeapon() {
            return weapon;
        }
    
        public void setWeapon(Weapon weapon) {
            this.weapon = weapon;
        }
    
        public int getAge() {
            return age;
        }
    
        public void setAge(int age) {
            this.age = age;
        }
        public void attack(){
            System.out.println("年龄为"+age+"名字为"+name+weapon.getCode()+"攻击");
        }
    }

=============
package neibulei.Demo6;

public class Weapon {
    private String code;

    public Weapon() {
    }

    public Weapon(String code) {
        this.code = code;
    }

    public String getCode() {
        return code;
    }

    public void setCode(String code) {
        this.code = code;
    }
}

======================

package neibulei.Demo6;

public class DemoTest {
    public static void main(String[] args) {
        Hero hero=new Hero();
        hero.setName("敌法");
        hero.setAge(29);
        Weapon weapon=new Weapon("恶魔之刃");
        hero.setWeapon(weapon);
        hero.attack();
    }

}
