This is a good time to explore a bit and add some styling if you want to do so. Here's an example

of something you can come up with:

import java.awt.Color;

import java.awt.Dimension;

import java.awt.Font;

import java.awt.Insets;

import javax.swing.BorderFactory;

import javax.swing.Box;

import javax.swing.BoxLayout;

import javax.swing.JButton;

import javax.swing.JFrame;

import javax.swing.JLabel;

import javax.swing.JTextField;

import javax.swing.SwingUtilities;

public class BMICalculator extends JFrame {

private final JTextField txtMass = makePrettyTextField();

private final JTextField txtHeight = makePrettyTextField();

private final JButton btnCalc = makePrettyButton("Calculate BMI");

public BMICalculator() {

super();

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

setTitle("BMI Calculator");

getContentPane().setLayout(

new BoxLayout(getContentPane(), BoxLayout.PAGE_AXIS));

txtMass.setPreferredSize(new Dimension(200,30));

txtHeight.setPreferredSize(new Dimension(200,30));

txtMass.setMaximumSize(txtMass.getPreferredSize());

txtHeight.setMaximumSize(txtHeight.getPreferredSize());

getContentPane().setBackground(new Color(232, 240, 255));

getContentPane().add(makePrettyLabel("Your mass (kg):"));
