Question

是否可以通过实现接口进行两个独立的类通信，如果是，如何进行通信？

Answer 1

我认为使用接口在这里有点极端，但我假设这是一个更大问题的简化

public interface SomeInterface {

    public void giveString(String string);

    public String getString();

}

public class Class1 implements SomeInterface{

    String string;

    public Class1(String string) {
        this.string = string;
    }

    //some code

    @Override
    public void giveString(String string) {
        //do whatever with the string
        this.string=string;

    }

    @Override
    public String getString() {
        return string;
    }



}

public class Class2 implements SomeInterface{

    String string;

    public Class2(String string) {
        this.string = string;
    }

    //some code

    @Override
    public void giveString(String string) {
        //do whatever with the string
        this.string=string;

    }

    @Override
    public String getString() {
        return string;
    }

}

public class Test{

    public static void main(String args[]){
        //All of this code is inside a for loop
        Class1 cl1=new Class1("TestString1");
        Class2 cl2=new Class2("TestString2");

        //note we can just communicate now, no interface
        cl1.giveString(cl2.string);


        //but we can also communicate using the interface
        giveStringViaInterface(cl2,cl1);
    }

    //any class that extended SomeInterface could use this method
    public static void giveStringViaInterface(SomeInterface from, SomeInterface to){
        to.giveString(from.getString());
    }



}

两个使用Interface进行通信的独立类
