Core Java, OOP, and Exception Handling

1.1

Develop programs that apply control flow, strings, arrays, matrices, classes, and validation.

  • Easy: Count vowels, consonants, digits, spaces, and special characters.
  • Medium: Add, subtract, and multiply matrices after dimension checks.
  • Hard: Implement account creation, deposit, withdrawal, and balance display.

1.2

Apply classes, constructors, encapsulation, inheritance, abstraction, and runtime polymorphism.

  • Easy: Build a Product class with constructors and a display method.
  • Medium: Model a library with a Book base class and specialised subclasses.
  • Hard: Develop a student-teacher system through an abstract Person class.

1.3

Use built-in and custom exceptions to keep application state valid and provide clear recovery messages.

  • Easy: Validate input for a square-root calculation.
  • Medium: Simulate ATM withdrawal with PIN and balance exceptions.
  • Hard: Manage university enrolment through custom exceptions.

Recommended workflow

How to use each worksheet

  1. Review the linked prerequisite concepts before starting the task.
  2. Attempt the problem statement and algorithm independently.
  3. Compare the implementation with the explained program and sample output.
  4. Test boundary and invalid cases, not only the sample values.
  5. Complete the viva questions and submission checklist.
