In this article, the editor introduces in detail "how to achieve bridging mode in Java". The content is detailed, the steps are clear, and the details are handled properly. I hope this article "how to achieve bridging mode in Java" can help you solve your doubts.

The bridge mode (Bridge Pattern) is used to decouple abstraction and implementation so that the two can change independently. This type of design pattern belongs to structural pattern, which decouples the two by providing a bridge structure between abstraction and implementation. This pattern involves an interface that acts as a bridge, making the function of the entity class independent of the interface implementation class. These two types of classes can be structurally changed without affecting each other.

Realize

We have a DrawAPI interface as a bridge implementation and entity classes RedCircle and GreenCircle that implement the DrawAPI interface. Shape is an abstract class that will use DrawAPI's objects. BridgePatternDemo, our demo class uses the Shape class to draw circles of different colors.

Step 1

Create a bridge implementation interface.

DrawAPI.javapublic interface DrawAPI {public void drawCircle (int radius, int x, int y);} step 2

Create an entity bridge implementation class that implements the DrawAPI interface.

RedCircle.javapublic class RedCircle implements DrawAPI {@ Override public void drawCircle (int radius, int x, int y) {System.out.println ("Drawing Circle [color: red, radius:" + radius + ", x:" + x + "," + y + "]") }} GreenCircle.javapublic class GreenCircle implements DrawAPI {@ Override public void drawCircle (int radius, int x, int y) {System.out.println ("Drawing Circle [color: green, radius:" + radius + ", x:" + x + "," + y + "]");}} step 3

Create an abstract class Shape using the DrawAPI interface.

Shape.javapublic abstract class Shape {protected DrawAPI drawAPI; protected Shape (DrawAPI drawAPI) {this.drawAPI = drawAPI;} public abstract void draw ();} step 4

Create an entity class that implements the Shape interface.

Circle.javapublic class Circle extends Shape {private int xpeny, radius; public Circle (int x, int y, int radius, DrawAPI drawAPI) {super (drawAPI); this.x = x; this.y = y; this.radius = radius;} public void draw () {drawAPI.drawCircle (radius,x,y);}} step 5

Use the Shape and DrawAPI classes to draw circles of different colors.

BridgePatternDemo.javapublic class BridgePatternDemo {public static void main (String [] args) {Shape redCircle = new Circle (100jing100,10, new RedCircle ()); Shape greenCircle = new Circle (100,10, new GreenCircle ()); redCircle.draw (); greenCircle.draw ();}} step 6

Execute the program and output the result:

Drawing Circle [color: red, radius: 10, x: 100100] Drawing Circle [color: green, radius: 10, x: 100,100] here, this article "how to implement bridging mode in Java" has been introduced.
