JAVA类之间的双向通信
我希望能够在GUI中创建客户机类的实例,然后将GUI.this作为客户机构造函数的参数传递给客户机构造函数,但我不确定具体如何做。我知道我错过了一些明显的东西!我希望能够从任何一个类调用另一个类上的方法。显然,我已经注释掉了代码,因为我不知道在不合并类的情况下如何或应该如何实现这种双向通信!我想能够做的事情,如通过发送一个命令,通过客户端从GUI类时,“向上”按钮是在GUI上点击等。感谢事先的帮助 客户端类:JAVA类之间的双向通信,java,swing,class,parameter-passing,this,Java,Swing,Class,Parameter Passing,This,我希望能够在GUI中创建客户机类的实例,然后将GUI.this作为客户机构造函数的参数传递给客户机构造函数,但我不确定具体如何做。我知道我错过了一些明显的东西!我希望能够从任何一个类调用另一个类上的方法。显然,我已经注释掉了代码,因为我不知道在不合并类的情况下如何或应该如何实现这种双向通信!我想能够做的事情,如通过发送一个命令,通过客户端从GUI类时,“向上”按钮是在GUI上点击等。感谢事先的帮助 客户端类: public class Client{ //static playe
