passing values across classes


I am doing a Java application in which i have two .java files (Connect.java and Handler.java).In Connect.java i have a function where i am getting some values from some other Response.java file . Now i need to pass these values as input parameters to a function in Handler.java . Following is my java file.Can any one help me please...?

Connect.java:

public class Connect
{

    private Response obj_response;
    public String UserId;
    public String LocationIpAddress;
    public String PassWord;

    public Connect(Response p_response)
    {
        obj_response=p_response;
    }

    public ConnectResponse handleConnect()
    {   

        try
        {   
            //values got from Response.java file
            String UserId=obj_response.getUserId();
            String LocationIpAddress=obj_response.getLocationIpAddress();
            String PassWord=obj_response.getPassWord();
        }
        catch(IOException e)
        {
            System.out.println("IO Exception");
        }

        return null;

    }
}

How can i implement my Handler.java?

Handler, Connect, Response - it is pretty hard to tell, what those classes are supposed to model. My suggestion: try to find better names for those classes.

It looks like you have some sort of connection mechanism where you receive a response (from another service) and prepare it with some kind of (response-)handler for further processing (hope my crystal ball is not too dirty)

Without changing your actual design too much - the Connect class should own an instance of Handler (composition). The Handler class needs to offer one single method that takes a Response and does the handling:

public class Handler {
  public void handle(Response response) {
    // do what has to be done with response
  }
}

public class Connect {
  private Handler handler = new Handler();
  //...
  public ConnectResponse handleConnect() {   
       // ...
       handler.handle(obj_response);
       // create and return ConnectResponse
  }
}

You can either pass the parameters you need through the constructor of your Handler.java, or else, pass the data you need as function parameters. Did you try something out first?
