  1. Read the Java documentation on access modifiers to understand their roles
  2. Build a simple Java program to test the effects of different access modifiers
  3. Run the program with a private main class to observe the JVM's behavior
  4. Configure the access modifiers to achieve the desired level of encapsulation
  5. Test the program with different access modifier combinations to solidify understanding
