Java Como faço pra salvar?

[Matheus Cahu]

Olá, recentemente estive trabalhando em um código para regular o inventário, porém, um dos problemas que eu tive foi que seria necessário fazer um sistema para salvar a quantidade, e outro para registrar qual foi a última vez que o inventário foi alterado, como eu poderia fazer isso?

CODE

public class Menu extends javax.swing.JFrame {

    private int tubo5;

    /**
     * Creates new form Menu
     */
    public Menu() {
        initComponents();
    }

    /**
     * This method is called from within the constructor to initialize the form.
     * WARNING: Do NOT modify this code. The content of this method is always
     * regenerated by the Form Editor.
     */
