Welcome to the ICSE Computer Applications repository—a structured collection of ICSE Java programs for practice and revision, designed specifically for students in Class 8, 9, and 10.

This repository is an independent open-source educational resource. It is not officially affiliated with, authorized, maintained, sponsored, or endorsed by the Council for the Indian School Certificate Examinations (CISCE). The term "ICSE" is used only to identify the syllabus. Always check the official CISCE website for the actual syllabus and official specimen papers.

Learning Java can be challenging. This project was created to provide a structured environment for practicing programming concepts learned in school. By providing tested, clear code that follows the syllabus, this repository aims to:

1. Support Learning: Provide correct examples of standard ICSE programs (e.g., checking prime numbers, working with strings, sorting arrays).
2. Facilitate Practice: Offer a codebase where code can be run, tested, and modified to understand how it works.
3. Archive Past Papers: Maintain a structured collection of solutions for past board papers, specimen papers, and school exams.
4. Introduce Open Source: Demonstrate how developers collaborate using tools like GitHub.

To make navigation straightforward, the folders are organized according to a typical academic year:

• class8/, class9/ & class10/: The primary directories for each grade. Inside them are:
  • [Chapter_Name]/[Textbook_Name]/: Programs sorted by chapter (e.g., Arrays) and the relevant textbook (e.g., Sumita Arora, APC).
  • exam/: Step-by-step solutions for official board exams and specimen papers.
  • Practice/: [Unofficial] Practice papers collected from various schools. Note: These are for extra practice and are not official board documents.
  • archive/: Older programs or topics that may not be in the current syllabus but are retained for reference.
• templates/: A library of basic algorithms (like Bubble Sort or a Palindrome checker). These can be copied and pasted into other programs to save time.
• website/: The source code that runs the project tutorial website.

The code can be executed in different environments based on preference.

BlueJ is the IDE most frequently used in ICSE schools.

1. Download: Click the green "Code" button at the top of this page and select Download ZIP, or clone the repository using Git:

   git clone https://github.com/indpriyanshuraj/ICSE-COMPUTER-JAVA.git

2. Extract: Unzip the downloaded file.
3. Open: Start BlueJ, go to Project > Open Project...
4. Run: Navigate to the folder containing the program to practice (e.g., class10/Arrays/) and open it. The programs can now be run directly inside BlueJ.

1. Clone the repository and open the folder in a code editor.
2. Open the terminal and navigate to the directory where the .java file is located.
3. Compile it: javac ProgramName.java
4. Run it: java ProgramName

Important: This repository only contains the raw Java source code (.java files).
