package com.troubleshooting.javase.exethis;

public class Girl {
    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public void marry(Boy boy) {
        System.out.println("我要嫁给" + boy.getName());
        boy.marry(this);
    }
}

package com.troubleshooting.javase.exethis;

public class Boy {
    private String name;
    private int 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;
    }

    public void marry(Girl girl) {
        System.out.println("我要娶" + girl.getName());
    }

    public void marry(Boy boy) {
        System.out.println("我要娶" + boy.getName());
    }

    public void shout() {
        if (this.age >= 22) {
            System.out.println("我到了结婚年龄了！");
        } else {
            System.out.println("你还是先谈谈恋爱吧！");
        }
    }

}

package com.troubleshooting.javase.exethis;

public class TestBoyGirl {
    public static void main(String[] args) {
        Boy b1 = new Boy();
        Girl g1 = new Girl();
        b1.setName("Jerry");
        b1.setAge(21);
        g1.setName("lucy");

        b1.marry(g1);
        g1.marry(b1);
        b1.shout();
    }
}

显示结果：
我要娶lucy
我要嫁给Jerry
我要娶lucy
你还是先谈谈恋爱吧！
