Navigation

I wanted to know how to do when to call a secondary window in Swing it left centered with the main window of the program. At the moment, when I call it it appears in the upper left corner.

Try this: 

frame.setLocationRelativeTo(null);

You can center a frame by using the setLocationRelativeTo () method. Here's an example: 

import javax.swing.JFrame;

public class MeuFRame {

    public static void main(String[] args) {
    JFrame janela = new JFrame("Frame vazio");
        janela.setSize(300,200);
    janela.setVisible(true);
    janela.setLocationRelativeTo(null); 
    }
}

You can learn more at documentation java.Procure (from a control + f) by the setLocationRelativeTo method.
