🏗️ How to Run

All files are plain Java. Compile and run from the terminal:

# Compile
javac FileName.java

# Run
java FileName

For programs organized into packages:

# Compile into package structure
javac -d . FileName.java

# Run with fully qualified class name
java com.example.ClassName

For programs requiring a custom CLASSPATH:

javac -cp ".;lib/*" FileName.java
java -cp ".;lib/*" FileName
