java application show progress on starting an application

Question

We have a big java desktop application, which takes about minute to start, Currently we use splash screen on stat-up, Is it possible to show progress bar with splash screen...? I mean when we start Some IDE like netbeans, IDEA Intellij, They show progress in form of progress-bar on splash screen. Progress bar might be showing progress in loading classes.. Thanks

You can use the java SplashScreen class. To set the progress bar you can draw a rectangle on the splash screen. As you hit different parts of your start up you can update this rectangle so that is acts like a progress bar. This demo code from Oracle show this. See the method titled renderSplashFrame()
