Java Program is a free Android app designed to provide source codes for various Java programs.

Java is one of the most widely used programming languages in the world. Web pages, mobile applications, and other interactive content all often utilize Java framework. Fluency and understanding of the Java programming language is essential for any aspiring developer. This app provides an easy cheat sheet when you're working in Java, so you don't have to spend time trying to remember a thousand different source codes and functions.

The app uses a minimalist interface to provide its coding help. It's easy to navigate between different source codes and make notes. Each available source code is clearly listed on the app's home page. Additionally, the background and text colors are customizable. This is great for both personalization and for saving yourself from eye strain.

Currently the following source codes are available:

Calculator

Bank Management

Armstrong Number

Sum of series

Pattern Series

Palindrome Number

String Matching

Odd Number

Odd Even

Factorial

Fibonacci

...and several others.

Though not all Java source codes have been added to the app, there are future updates planned that add more source codes, with the end goal being to categorize all currently available Java source codes in the world. Right now, the most commonly used Java source codes are available, so the app is still helpful for most types of programming.

This app works as a handy cheat sheet for programming bases. It's also a good refresher for programmers who want to keep their knowledge sharp. It should be noted, though, that this isn't an education app. It's strictly for people who already know how to use Java. There are no tutorials or instructions explaining Java framework to newcomers. If you want to learn Java, you'd be better off seeking out a different tutorial app.
