Java Bridge mode

Bridge mode decoupling, its implementation of the definition. It is a structural pattern. This mode involves the interface acting as a bridge. This bridge makes the concrete class independent of the interface performer class.

Bridge mode decoupling, its implementation of the definition. It is a structural pattern.

This mode involves the interface acting as a bridge. This bridge makes the concrete class independent of the interface performer class.

These two types of classes can be changed without affecting each other.

Instance:

Interface Printer {public void print (int radius, int x, int y);} From WWW.J a v A2 s. C OM class Colorprinter implements Printer {@Override public void print (int radius, int x, int y) {System.out.pri
  Ntln ("Color:" + Radius + ", x:" +x+ "," + y + "]); Class Blackprinter implements Printer {@Override public void print (int radius, int x, int y) {System.out.prin
  TLN ("Black:" + Radius + ", x:" +x+ "," + y + "]);
  } abstract class Shape {protected Printer print;
  Protected Shape (Printer p) {this.print = P; 
public abstract void Draw ();

  Class Circle extends Shape {private int x, y, radius;
   public Circle (int x, int y, int radius, Printer draw) {super (draw); 
   this.x = x; 
   This.y = y;
  This.radius = radius;
  public void Draw () {print.print (radius,x,y); } public class Main {public static void main (string[] args) {Shape redcircle = new Circle (100,100, New Colorp
   Rinter ()); Shape blackcircle = new Circle (100, Blackprinter, New ());
   Redcircle.draw ();
  Blackcircle.draw ();
