Doing so is called an explicit constructor invocation. Here's another Rectangle class, with a different implementation from the one in the Objects section. public class Rectangle { private int x, y; private int width, height; public Rectangle() { this(0, 0, 1, 1); } public Rectangle(...
This file configures the LoginModule(s) used in the application. It specifies the location of the LoginModule(s) and, if there are multiple LoginModules, the order in which they are executed. This file enables Java applications to remain independent from the authentication technologies, which are...
