Yes you can. Unfortunately Java is not well suited for this task (for various reasons). I would suggest you buy an arduino set and learn what it can do regarding controlling devices and receiving input from sensors, so you know more about what is possible.
If you want to edit a value easily based on something else in the program, you can make it so the number is a variable instead. Judging by the code as well, you want there to be a new line, currently it’s not doing that since you need to use “\n” So the code should … Read more
Many Swing components support printing out of the box You could use something as simple as JTextArea.print to get started, for example import java.awt.BorderLayout; import java.awt.Color; import java.awt.EventQueue; import java.awt.Font; import java.awt.Graphics2D; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.awt.geom.Rectangle2D; import java.awt.image.BufferedImage; import java.awt.print.PageFormat; import java.awt.print.Paper; import java.awt.print.Printable; import java.awt.print.PrinterException; import java.io.File; import java.io.IOException; import java.util.StringJoiner; import … Read more
Add an actionlistener to your JButton and it will tell you when its been clicked like so: someButton.addActionListener(new ActionListener(){ public void actionPerformed(ActionEvent e) { //the button was pressed and do your stuff here. } }
You’re not using a LayoutManager of any kind. The JButton will try to inherit the size of the parent container, as the default for a JFrame is BorderLayout (specifically, BorderLayout.CENTER). You could try using button.setPreferredSize(x, y); However I don’t think this would be enough by itself. Call getContentPane on the Jframe, and set a layout … Read more

The constructor Time(Build, String) accept a Build instance as first … Read more
Basically, you draw what ever you want around the center of the component, based on it’s width and height public void paintComponent(Graphics g) { super.paintComponent(g); int width = getWidth() – 1; int height = getHeight() – 2; g.drawLine(width / 2, 0, width / 2, height); g.drawLine(0, height / 2, width, height / 2); } Check … Read more
Sounds like you need a Swing TabbedPane With the JTabbedPane class, you can have several components, such as panels, share the same space. The user chooses which component to view by selecting the tab corresponding to the desired component. If you want similar functionality without the tab interface, you can use a card layout instead … Read more
make sure that Inventory extends JPanel this makes Inventory to behave as a subclass of a JPanel, and thus you can use it in the same way.
