Java Lab Experiments (B.Tech CSE - 4th Semester)

This repository contains the experiments performed during the Java Lab in the 4th semester of my B.Tech (CSE).

Tech Stack

• Java

IDE

• IntelliJ IDEA

Folder Structure

Typical structure in this repo:

• Java/ (or your main lab folder)
  • com/company/ - Java package com.company
    • \*.java - individual experiment programs (each usually has a main method)
• .gitignore (at project root and/or inside folders as needed)
• README.md

Note: Java package folders must match the package name inside the file (example: package com.company; should be located in com/company/).

How to Run (IntelliJ IDEA)

1. Open the project in IntelliJ IDEA.
2. In the Project view, go to com/company/.
3. Open any experiment \*.java file that contains public static void main(String[] args).
4. Click the green Run icon near main (or right-click the file -> Run).

How to Run (Command Line)

From the folder that contains com/:

1. Compile (example using one file):
   • javac com/company/YourClassName.java
2. Run:
   • java com.company.YourClassName

Replace YourClassName with the class you want to execute.

Experiments

This folder includes multiple Java lab experiments such as:

• Constructors in Java (default, parameterized, copy)
• Basic OOP concepts (classes, objects, methods)
• Input/output using System.out.println
• Additional lab programs added over the semester

Notes

• Keep file name and public class name the same (example: Sample.java must contain public class Sample).
• Keep each experiment inside the correct package folder (example: com/company/).
• Some files may be intentionally ignored via .gitignore (example: local helper files).
