I have a problem with elements showing up on my GUI. I am creating a very simple program where I ask the user to input three different integers in three different boxes and a button to add the numbers together when it is pressed. Right now, I have created a button, a textfield, and a label but there's a problem: The button, textfield, and label does not appear on the GUI. I have to hover over the button area for it to appear and same with the textfield. The label doesn't show up at all even when I hover where it's supposed to be. Any reason why this is happening? Here's my code
import javax.swing.*;
public class ButtonPractice extends javax.swing.JFrame
{
public static void main(String[] args)
{
JFrame box = new JFrame("Simple addition");
box.setVisible(true);
box.setSize(500,500);
box.setResizable(false);
box.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel = new JPanel();
panel.setLayout(null);
box.add(panel);
JTextField inputNumOne = new JTextField("Integer here");
inputNumOne.setBounds(225,50,200,30);
panel.add(inputNumOne);
JLabel labelNumOne = new JLabel("First integer");
labelNumOne.setBounds(100,50,150,50);
panel.add(labelNumOne);
JButton combiner = new JButton("Concactentate");
//positioning of the button on the panel
combiner.setBounds(175,300,125,50);
panel.add(combiner);
}
}
Thanks in advance to those who review the code!
