We implement the LoginFormDemo.java class in which we create two text fields, i.e., text1 and text2, for setting the username and password. In Java, we can develop the login form by using Swing technology. If the users provide unauthentic credentials, they will not be able to forward the login form. Each user should have a unique username that can be an email, phone number, or any custom username.Īfter submitting the login form, the underlying code of the form checks whether the credentials are authentic or not to allow the user to access the restricted page. A login form contains only two fields, i.e., username and password. The splash-screen window has an overlay surface with an alpha channel, and this surface can be accessed with a traditional Graphics2D interface.In Java, a form for entering authentication credentials to access the restricted page is referred to as a Login form. Typically, a developer wants to keep the splash-screen image on the screen and display something over the image. If the application has not created the splash screen at startup through the command-line or manifest-file option, the getSplashScreen method returns null. ![]() Only a single instance created within this class can exist, and this instance can be obtained using the getSplashScreen() static method. An application cannot create an instance of this class. SplashScreen class is used to close the splash screen, change the splash-screen image, obtain the image position or size, and paint in the splash screen. The figure below represents an example of the Java application splash screen developed as an animated gif file. The splash screen can display any gif, png, or jpeg image, with transparency, translucency, and animation. A Java application launcher is able to decode an image and display it in a simple non-decorated window. The resulting delay of several seconds has made the use of a Java™ technology-based splash screen less than desirable.įortunately, Java™ SE 6 provides a solution that allows the application to display the splash screen much earlier, even before the virtual machine starts. Before the splash screen can pop up, the application has to load and initialize the Java™ Virtual Machine (JVM), AWT, Swing, and sometimes application-dependent libraries as well. However, because the main purpose of a splash screen is to provide the user with feedback about the application's startup, the delay between the application's startup and the moment when the splash screen pops up should be minimal. Java Foundation Classes, both Swing and Abstract Windowing Toolkit (AWT), enable a developer to create splash screens in Java technology applications. Providing information that is only needed once per visit.Indicating to the user that the application is launching during long startup times.Typically splash screens are used for the following purposes: ![]() Almost all modern applications have a splash screen. ![]()
