Question

I have a large Java project(a SQL-backed personnel system, in Java 6) with a Text Interface which is fairly complex. For example, in the main class when the user picks the person option, it will call this code:

    int choice = new Integer(line);
    if(choice >= 1 && choice <= 13){  
        exit = false;
        models[choice - 1].showMenu();
    }

And then it eventually calls the Person class, whose constructor looks like this:

  public Person(Connection con){
    conn = con;
    item = "Person";
    count = getLastID() + 1;
  }

and a sample menu option to get all of a person’s info looks like so:

  protected void queryGetAll(){
      Statement stmnt = null;
      // create prepared statement
      try {
          stmnt = conn.createStatement();
          ResultSet result = stmnt.executeQuery("SELECT * FROM person");
          System.out.println("");
          System.out.println("");
          System.out.println(" *****************       LIST OF ALL PERSONS      ***************** ");
          System.out.println("");
          while(result.next()){
              System.out.print(" ID: " + result.getString("per_id") + "   |   ");
              System.out.print(" NAME: " + result.getString("name") + "   |   ");
              System.out.print(" STREET: " + result.getString("street") + "   |   ");
              System.out.print(" CITY: " + result.getString("city") + "   |   ");
              System.out.print(" ZIP CODE: " + result.getString("zip_code") + "   |   ");
              System.out.print(" E-MAIL: " + result.getString("email") + "   |   ");
              System.out.println(" GENDER: " + result.getString("gender"));
          }
          System.out.println("");
          System.out.println("");
          stmnt.close();
        } catch(SQLException ex) {
          System.err.println("SQLException: " + ex.getMessage());
        }
  }

I want to convert this whole TUI into a GUI using NetBeans, which makes GUI building easy. The issue is I don’t know how to “grab” the results, i.e, what do I put in the GUI code here:

this.textBox.setText("The person's information" + iDontKnowWhatsHere  );

Is there any work-around here? If it’s possible to grab what by default is put onto the console, and just shoot it to the GUI text-box I’d be happy to do that. Any guidance/tips appreciated, Thanks

Answer 1

I think the most suitable component here is JTable.

Create one Vector of String as columns ‘ names and Vector of Vector for the table data.
Main Vector contain rows (also Vectors) and each rowVector has all the row values.

Then create a DefaultTableModel and a JTable based on the model (JTable also has construtor to pass the columns and data)
