Java-方法重载时 调用未定义的对象属性

public TestWayReload(int id,String name){
	super();
	this.id =id;
	this.name=name;
}

public TestWayReload(int id ,String name,String pwd){
	this.id = id;
	this.name= name;
	this.pwd= pwd;
}

public static void main(String[] args){
	
	TestWayReload u1 = new TestWayReload();
	
	TestWayReload u2 = new TestWayReload(101,"李寻欢");
	System.out.println(u2.id);
	System.out.println(u2.name);
	System.out.println(u2.pwd);
	System.out.println("##########");

	TestWayReload u3 = new TestWayReload(100,"李寻欢","233333");
	System.out.println(u3.id);
	System.out.println(u3.name);
	System.out.println(u3.pwd);
	System.out.println("##########");
}
