Java学习笔记：this使用总结

public class Point {
public int x = 0;
public int y = 0;

//constructor
public Point(int x, int y) {
this.x = x;
this.y = y;
}
}

public class Rectangle {
private int x, y;
private int width, height;

public Rectangle() {
this(0, 0, 1, 1);
}
public Rectangle(int width, int height) {
this(0, 0, width, height);
}
public Rectangle(int x, int y, int width, int height) {
this.x = x;
this.y = y;
this.width = width;
this.height = height;
}
...
}
