Swing is a Java Foundation Classes [JFC] framework and an Abstract Window Toolkit [AWT] extension. Swing has much-improved functionality over AWT, including additional components, expanded component features, and superior event management with drag-and-drop support. Unlike AWT, Java Swing provides platform-independent and lightweight components. Features Of Swing Class : Pluggable look and feel Uses MVC architecture […]

Graphical User Interface (GUI) programming is supported by the Abstract Window Toolkit (AWT). Java AWT components are platform-dependent, which means they are shown in accordance with the operating system’s view. AWT is heavyweight, which means that its components consume the resources of the underlying operating system (OS). This illustrates how Abstract Window Toolkit applications are […]

To sort the objects of user-defined classes, a comparator interface is utilized. A comparator object can compare two items of the same type.This interface may be found in java.util package and includes two methods: compare(Object obj1,Object obj2) equals (Object element). It supports different sorting sequences, which means you can sort the items based on any […]

The Comparable interface is used to compare an object of the same class with an instance of that class; it also enables data ordering for user-defined class objects. The class has to implement the java.lang.Comparable interface to compare its instance, it provides the compareTo() method, which accepts an object of that class as an argument. Its sorting algorithm is determined by the type of object used by the interface. If the object type is a string, it is sorted lexicographically. Else, If the object type is a wrapper class object, such as an integer […]
