The Meaning and Usage of java Static Agent

Description

1. If the proxy exists before the program runs, then this proxy becomes a static proxy. In this case, the proxy is usually defined by us in Java code.

2, 1 Generally speaking, the proxy class and delegate class in a static proxy will implement the same interface or give birth to the same parent class.

Instances

/**
 *  Both the delegate class and the proxy class implement the Sell Interface 
 */
public interface Sell {
    void sell();
    void ad();
}

Instance extension:

In Java, agent is also such a concept. Let's look at a chestnut:

First, create a star class Stars:

public class Stars implements IStars{
  private String name;

  public Stars(String name) {
    this.name = name;
  }

  public String getName() {
    return name;
  }

  public void setName(String name) {
    this.name = name;
  }

  public void sing(){
    System.out.println(getName() + "  Sing 1 A song .");
  }

  public void dance(){
    System.out.println(getName() + "  Jump 1 Dance .");
  }
}

This is the corresponding interface:

public interface IStars {
  void sing();
  void dance();
}
