I’m very new to java and having fun.
I installed an eclipse web developer to code GUI easily.
I want to know if the code made by the web developer still works on eclipse which web developer isn’t installed.

+) Does every function of web developer is limited to basic JDK?
This is the code that is generated by eclipse web developer.
Thank you.

import java.awt.BorderLayout;
import java.awt.EventQueue;

import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.border.EmptyBorder;
import javax.swing.JLabel;
import java.awt.Font;

public class helpme extends JFrame {

    private JPanel contentPane;

    /**
     * Launch the application.
     */
    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {
            public void run() {
                try {
                    helpme frame = new helpme();
                    frame.setVisible(true);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        });
    }

    /**
     * Create the frame.
     */
    public helpme() {
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setBounds(100, 100, 450, 300);
        contentPane = new JPanel();
        contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
        setContentPane(contentPane);
        contentPane.setLayout(null);
        
        JLabel lblNewLabel = new JLabel("Thank you very much");
        lblNewLabel.setFont(new Font("MS Gothic", Font.BOLD, 16));
        lblNewLabel.setBounds(142, 44, 170, 55);
        contentPane.add(lblNewLabel);
    }
