Why this fits a Delhi student

Delhi is overwhelmingly a CBSE city, with ICSE/ISC and Cambridge schools alongside, so most Delhi students are an exact fit for this course.

What Java covers

9 units. Tap any unit to see its topics.

01Object-Oriented Foundations+
  • Object-oriented programming paradigm vs procedural
  • Principles of OOP: data abstraction, encapsulation, inheritance, polymorphism
  • Objects and classes; class as a composite/user-defined data type
  • Introduction to Java: applications vs applets, JVM, byte code, compilation process
  • Open source concepts and IDEs (BlueJ, NetBeans)
02Java Language Basics+
  • Character set, tokens, identifiers, literals
  • Keywords, escape sequences, ASCII and Unicode
  • Primitive data types and variables
  • Type conversion: implicit (coercion) and explicit (casting)
  • Operators and expressions; operator precedence and associativity
03Control Flow and Iteration+
  • Conditional statements: if, if-else, nested if, switch-case
  • Iteration: while, do-while, for loops
  • Nested loops
  • Jump statements: break and continue
  • Building menu-driven and pattern programs
04Classes, Objects and Methods+
  • Defining classes, instance variables and methods
  • Constructors: default and parameterised; constructor overloading
  • Access specifiers and encapsulation (private data, public accessors)
  • User-defined methods; pure and impure methods; method overloading
  • Passing parameters: call by value and call by reference; the this keyword
  • Static (class) variables and methods
05Arrays and Strings+
  • Single and double dimensional arrays
  • Array traversal, searching (linear, binary) and sorting (selection, bubble)
  • String class and common methods: length, charAt, substring, indexOf, concat, replace, compareTo, equals
  • StringBuffer basics; manipulating and comparing strings
  • Wrapper classes, autoboxing and unboxing
06Inheritance and Polymorphism+
  • Base (super) and derived classes; extends keyword
  • Member access in derived classes; protected visibility
  • super keyword; redefinition and method overriding
  • Abstract classes and abstract methods; the Object class
  • Single and multilevel inheritance; runtime polymorphism
  • Interfaces and multiple implementation
07Recursion+
  • Concept of recursion and the call stack
  • Recursive methods: factorial, GCD, Fibonacci, power
  • Recursive binary search
  • Base case vs recursive case; number-base conversions
08Data Structures and Collections+
  • Stacks, queues and dequeues; implementation via classes
  • Defining data structures through interfaces with multiple implementations
  • Singly linked lists: algorithm and implementation
  • Binary trees and tree traversals (conceptual)
  • ArrayList and dynamic collections; iterating over collections
09Projects and Exam Practice+
  • End-to-end Java project: problem analysis, algorithm, coding and testing
  • Lab assignments aligned to ICSE Internal Assessment
  • Solved ICSE/ISC model and previous-year papers
  • Output prediction and debugging exercises

Students across Delhi

A student anywhere in Delhi can take Java with us — Anthony, Dwarka, Frank or Greater included — because the class is online and there is no centre to travel to. Delhi sits in Delhi, where the CBSE-affiliated schools (CBSE) runs alongside the national boards, so we are asked about both.

Every class is live at Indian Standard Time, in a small batch or one-to-one. Nothing is pre-recorded, so a student in Delhi asks questions in the moment. Recordings are provided for revision only.

Shubhranshu enjoyed the classes with Kajal Mam as she taught really well. She kept him engaged even in online classes. He joined the classes just few months before exams and still managed to score well as Kajal Mam taught him strategically and continuously. Hats off to her hard work and perseverance.
