Java Constructor Error: Constructor is defined, not found

Receiving this error to which most results say Define the constructor, homeboy. Any insights into what error I am making because I thought it is defined in my class. I'm pretty new to java, don't shred me if it's obvious.

Error: constructor KServer in class KServer cannot be applied to given types;  
                KServer server = new KServer(port);
   required: no arguments
   found: int
   reason: actual and formal argument lists differ in length
1 error

KServer.java

public class KServer {
    private int port;

    //isn't this the constructor defined?
    public void KServer(int PORT) {
        port = PORT;
    }
    public void Run() {...}
}

KServ.java

public class KServ {
    public static void main(String[] args) {

    if (args.length != 1) {
        System.err.println("Usage: java KServ <port number>");
        System.exit(1);
    }

    int port = Integer.parseInt(args[0]);
    KServer server = new KServer(port);
    server.Run();

    }

}

Remove the word void from the constructor definition :

public KServer(int PORT) {
    port = PORT;
}

No return type for a constructor, otherwise you define a method.

public KServer(int PORT) {
    port = PORT;
}
