我正在尝试连接到套接字,然后检查它是否已连接。我的问题是我的socket是连接的,但是当我询问它是否时,它返回null。
我如何获得我的联系:
package main;
import java.io.IOException;
import java.net.Socket;
public class getIrcConnection {
String Server = "tmi.twitch.tv";
int Port = 80;
declars declars = new declars();
public getIrcConnection() throws IOException{
this.declars.socket = new Socket(Server, Port);
}
}
我的套接字存储位置:
package main;
import java.net.Socket;
public class declars {
Socket socket;
}
我如何检查连接:
package main;
public class checkIrcConnection {
declars declars = new declars();
public checkIrcConnection() {
if (this.declars.socket.isConnected()) {
System.out.println("Connected");
}
}
}
所有这些都是在主要方法中执行的:
package main;
public class Main {
public static void main(String[] args) throws Exception {
getIrcConnection gic = new getIrcConnection();
checkIrcConnection cic = new checkIrcConnection();
}
}

个对象。一个是您设置declars
而另一个是gic.declars
。即你正在使用你未设置的那个。
我建议您逐步调试调试器中的代码,因为您有一个简单的混淆,这应该从调试器中显而易见。
答案 1 :(得分:0)
首先以面向对象的方式组织代码。将类视为对象,这些对象必须具有公共属性和常用操作。然后将所有功能分发给对象。如果你这样做,调试和理解错误就会容易得多。
如果你想对URL做一些http
请求,并处理返回的结果,那么使用一些库会很好。例如,您可以使用unirest
或者如果您想在java中使用套接字编程,可以参考java tutorial about sockets
