下面的this 是指的什么public class W { public W foo(){ return this; } }继承时可以写与父类 完全相同的方法吗

下面的this 是指的什么public class W { public W foo(){ return this; } }继承时可以写与父类 完全相同的方法吗 请帮我解释一下Java程序,其中的this.x指什么,右边的x指什么.public class Point{public int x=0;public int y=0;public Point(int x,int y){this.x=x;this.y=y;}}我看书上写着this.x=x;是初始化字段x的值,this代表当前的对象 public Node(object data,Node next) { this.Data = data; this.Next = next; 求当中this的解释!是指当 java 里开头的public 和public class有什么区别?就是public,public class,class 的区别. in the public和in public的区别用法 意思 区别是in the public 不是to the public 请问：in public 和 the publicin public 是否是 在公共场合的意思?the public 是否是 公众的意思?前者是指地点,后者是指人? if(c.color == this.color && c.height == this.height && c.weight == this.weight) 这里this指的是?public class TestEquals { public static void main (String[] args) { Cat c1 = new Cat(1,2,3); Cat c2 = new Cat(1,2,3); System.out.println(c1 == c2); C++里面的public什么意思啊 下面是一个类的定义:public class _int Myclass_________下面是一个类的定义:public class _int Myclass___________ { int x,y; Myclass ( int i,___=?____) // 构造函数 { x=i; y=j; } } in the public.in public,the public place的区别 谁能帮我解释下面每段代码的含义,package com.mujinlei.study;public class JavaClassStudyTest {public JavaClassStudyTest(){}public JavaClassStudyTest(String s){}public JavaClassStudyTest(double d){}public JavaClassStudyTest(int i){}private 求java程序 输出一个圆的圆心是（3.4） 半径是5public class Circle{Point center;int radius;public Circle(Point center,int radius){this.center=center;this.radius=radius;}public int getCenter(){return this.center;}pubic int getRadius(){re public administration 与public management 的区别 C#语法问题 this的用法public class Users{private int _userid;private string _username;private string _userpwd;public int UserId{get { return this._userid; }set { this._userid = value; }}public string UserName{get { return this._username; }set { 阅读下面C#代码,找出错误并改正.class A{private int x;public A(int x){this.x = x;}public int MyX{get{return x;}}}class B{public static void Main(){A b = new A(10);b.MyX = 100;Console.WriteLine(b.MyX);}}将改正之后的代码写上就行 “公共关系”用英语怎么说?我知道public relations是对的,但也见过public relation；还有public relationship,public relationships都对不对呢? in public和to the public的意思用法有什么 区别? a privately incorporated company, or public or public listed companies都是什么类型的公司呢
