I am Running into a java.net.BindException: Address already in use (Bind failed) on a server-client socket app
I am trying to learn about Java sockets using a Youtube tutorial as a reference. My code seems to match everything in the video (except variables names) but, when trying to run the server and then the client sockets, I get:
Exception in thread "main" java.net.BindException: Address already in use (Bind failed)
I have tried even printing out the local port just to make sure I connect to the right available port but, nothing works. Is there any documentation I can look into to solve this problem? or any guidance?
Server.java
public class serverSocket {
public static void main(String args[]) throws IOException{
String message, serverResponse;
ServerSocket serverSocket = new ServerSocket(56789);
System.out.print(serverSocket.getLocalPort());
Socket acceptClientRequestSocket = serverSocket.accept();
Scanner serverScanner = new Scanner(acceptClientRequestSocket.getInputStream());
message = serverScanner.next();
System.out.println(message);
serverResponse = message.toUpperCase();
PrintStream newMessage = new PrintStream(acceptClientRequestSocket.getOutputStream());
newMessage.println(serverResponse);
}
}
Client.java
public class clientSocket {
public static void main(String args[]) throws UnknownHostException, IOException {
String message,outputMessage;
Scanner clientInput = new Scanner(System.in);
Socket clientSocket = new Socket("localhost",56789);
Scanner incomingStream = new Scanner(clientSocket.getInputStream());
System.out.println("Enter a message");
message = clientInput.next();
PrintStream printClientStream= new PrintStream(clientSocket.getOutputStream());
printClientStream.println(message);
outputMessage = incomingStream.next();
System.out.println(outputMessage);
}
}
Is there any documentation I can look into to solve this problem? or any guidance?
