Why my inner class DO see a NON static variable?
- by Roman
Earlier I had a problem when an inner anonymous class did not see a field of the "outer" class. I needed to make a final variable to make it visible to the inner class. Now I have an opposite situation. In the "outer" class "ClientListener" I use an inner class "Thread" and the "Thread" class I have the "run" method and does see the "earPort" from the "outer" class! Why?
import java.io.IOException;
import java.net.*;
import java.io.BufferedReader;
import java.io.InputStreamReader;
public class ClientsListener {
private int earPort;
// Constructor.
public ClientsListener(int earPort) {
this.earPort = earPort;
}
public void starListening() {
Thread inputStreamsGenerator = new Thread() {
public void run() {
System.out.println(earPort);
try {
System.out.println(earPort);
ServerSocket listeningSocket = new ServerSocket(earPort);
Socket serverSideSocket = listeningSocket.accept();
BufferedReader in = new BufferedReader(new InputStreamReader(serverSideSocket.getInputStream()));
} catch (IOException e) {
System.out.println("");
}
}
};
inputStreamsGenerator.start();
}
}
