Difference between IDE vs API vs Framework vs SDK

IDE (Integrated development environment)
IDE is any application that helps you to

  • Write code in them
  • Compile the application
  • Debug the application
  • Refactoring the code
  • Building your application
Example: Eclipse, IntelliJ IDEA, Netbeans, Visual Studio, etc.


API (Application Programming Interface)
APIs are actually interface to any library. It actually explains about the various methods/functions available in the library and how we can make use of those through the code.

 Example: JUnit API

Framework 
A framework is a kit or generic structure that provides a skeleton architecture with which specific software can be implemented. It also a library (or a collection of libraries that work together) that provides a specific coding structure & pattern (thus the word, framework).

Example: Swing Framework contains a set of classes that provides more powerful and flexible GUI components.
Spring Framework.

SDK (Software Development Kit)
SDK contains a complete set of libraries, APIs, IDEs etc., that is required for development activity.

Example: Android SDK, which provides everything you may need for Android development.

Creating single instance of Java Application

Prerequisites: Basic Java project creation Knowledge in SWT/JFace dialog There are several ways to enforce a single instance of java application. Here I am going to explain about one of the most used way to create a single instance for any java application by using Server Socket class. Create a simple Java project. Call the below API before the initiation of the project. Surround this API in try/catch block so that if the API succeeds it will execute the application else custom user understandable error message is displayed.  Explanation: By creating a server socket instance by passing the port no and local address of the system as parameter one can monitor the application running in that specific port address in that specific system. If user tries to launch another instance of an application server socket throws exception.java.net.BindException: Address already in use: JVM_Bind exception . For the complete source code of this application please clone/...

Creating a System Tray notification with icon in Java

The Java language provides support for creating a popup notification with icon ad message. This can be done using many libraries in Java. Here I am going to demonstrate a simple way using AWT SystemTray . SystemTray class in Java: The SystemTray class represents the system tray for a desktop. On Microsoft Windows it is referred to as the "Taskbar Status Area", on Gnome it is referred to as the "Notification Area", on KDE it is referred to as the "System Tray". The system tray is shared by all applications running on the desktop.  On some platforms the system tray may not be present or may not be supported, in this case SystemTray.getSystemTray() throws UnsupportedOperationException. To detect whether the system tray is supported, use SystemTray.isSupported() method which returns true is it is supported.  For example: if (SystemTray.isSupported()) { System.out.println("System tray supported for this one!");         } else {     ...
