9 Sorts of Java Applications
10 There are principally 4 sorts of utilizations that can be made utilizing Java programming:
1) Independent Application
Independent applications are otherwise called work area applications or window-based applications. These are customary programming that we want to introduce on each machine. Instances of independent application are Media player, antivirus, and so forth. AWT and Swing are utilized in Java for making independent applications.
2) Web Application
