Java this关键字的使用案例详解

通过一个小案例来学习、理解一下this关键字的使用~~~

boy类

package myjava1;
public class boy {
	private string name;
	private int age;
	public boy() {	
	}
	public boy(string name,int age) {
		this.name = name;
		this.age = 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(this.name+ " 也想娶：" + girl.getname());
	}
	public void shout() {
		if(this.age >= 22) {
			system.out.println("可以了");
		}else {
			system.out.println("不可以");
		}
	}
}

girl类

package myjava1;
public class girl {
	private string name;
	private int age;
	public girl() {
	}
	public girl(string name,int age) {
		this.name = name;
		this.age = 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(boy boy) {
		system.out.println(this.name + " 想嫁给：" + boy.getname());
		boy.marry(this);
	}
	public void compare(girl girl) {
		if(this.age > girl.getage()) {
			system.out.println(this.getname() + "比" + girl.getname() + "大");
		}else if(this.age < girl.getage()) {
			system.out.println(this.getname() + "比" + girl.getname() + "小");
		}else {
			system.out.println(this.getname() + "和" + girl.getname() + "一样大");
		}
	}
}

boygirltest类

package myjava1;
public class boygirltest {
	public static void main(string[] args) {
		boy boy = new boy("罗密欧",21);
		boy.shout();
		girl girl = new girl("朱丽叶",18);
		girl.marry(boy);
		girl girl2 = new girl("祝英台",19);
		girl2.compare(girl);
		girl.compare(girl2);
		girl2.compare(girl2);
	}
}
