import java.awt.Frame;

public class NewFrame extends Frame

    public NewFrame() 
        // TODO Auto-generated constructor stub
        SplashScreen splash = new SplashScreen(1000);
        System.out.println("This is working");


     * @param args

        NewFrame newframe = new NewFrame();



This is showing me error

The constructor SplashScreen(long) is not visible

And this is the Splash screen code

import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Toolkit;

import javax.swing.BorderFactory;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JWindow;

class SplashScreen extends JWindow {
  private int duration;

  public SplashScreen(int d) {
    duration = d;

    JPanel content = (JPanel) getContentPane();
    int width = 450;
    int height = 115;
    Dimension screen = Toolkit.getDefaultToolkit().getScreenSize();
    int x = (screen.width - width) / 2;
    int y = (screen.height - height) / 2;
    setBounds(x, y, width, height);  
     content.add(new JLabel("Welcome to Company"), BorderLayout.CENTER);
    //Color oraRed = new Color(156, 20, 20, 255);
     Color oraRed = new Color(190, 10, 10, 255);
    content.setBorder(BorderFactory.createLineBorder(oraRed, 1));


    try {
    } catch (Exception e) {
  public static void main(String[] args) {
    SplashScreen splash = new SplashScreen(10000);

Constructors are public by default ,aren't they?

No, they are package access by default, justlike ordinary methods.

The error message refers to a constructor with a long parameter, but the only constructor takes an int.

Creation or modification of Swing components should normally be done on the Swing thread. Sleeping during a constructor while changing a swing component's visibility, all on the main thread is asking for trouble...
