Java-面向对象_构造器的重载

public class Person1 {
    String name;
    int age;
    double height;
    
    
    public Person1() {
        
    }
    //构造器的重载
    public Person1(String name,int age,double height) {
        //当形参名字和属性名字重名的时候，会出现就近原则;
        //当要表示对象的属性前加上this.来修饰，因此this代表的就是你创建的那个对象
        this.name= name;
        this.age = age;
        this.height = height;
    }
    public Person1(String a,int b) {
        name = a;
        age = b;
    }
}

Person1 p1 = new Person1("小明", 18);
        System.out.println(p1.name);
        System.out.println(p1.age);
        System.out.println();
        
        Person1 p2 = new Person1("小李", 19, 170.5);
        System.out.println(p2.name);
        System.out.println(p2.age);
        System.out.println(p2.height);
