Syllabus

Introduction

In this module, we will introduce the basics of programming languages, their types, and their significance. We will also learn how to plan and understand program flows using flowcharts and pseudocode, and finally, we will guide you through the installation and architecture of Java, setting the stage for deeper learning.

Basics of Java - Input/Output, Debugging and Datatypes

In this module, we will explore Java's input/output methods, essential for interacting with users. We will also dive into debugging techniques, helping you troubleshoot issues in your code, and discuss various data types in Java, enabling you to select the best one for your programs.

Conditionals & Loops

In this module, we will focus on conditionals and loops, fundamental concepts for controlling the execution flow of a Java program. You will learn how to apply if-else statements and various types of loops to manage decision-making and repetitive tasks in your code.

Switch Case

In this module, we will explore the switch-case statement, a powerful tool for handling multiple conditions in Java. We will also examine its advantages and when to use it over traditional if-else structures for more efficient decision-making.

Functions or Methods in Java

In this module, we will introduce the concept of functions or methods in Java, key building blocks for creating modular, reusable code. You will learn how to declare methods, pass parameters, and return values to optimize your program's structure and performance.

Introduction to Arrays and ArrayList in Java

In this module, we will cover arrays, a foundational data structure in Java, and explore multidimensional arrays for storing complex data. Additionally, we will delve into ArrayLists, which offer dynamic resizing capabilities, providing more flexibility than traditional arrays.

Strings and StringBuilders

In this module, we will compare Strings and StringBuilders in Java, highlighting their differences in terms of performance and usage. You will also learn when to use StringBuilder for mutable strings to enhance your program's efficiency.

Bitwise Operators & Number Systems

In this module, we will introduce number systems and explore their relevance in computing. We will then dive into bitwise operators, showing how they can be used for efficient data manipulation, and solve practical problems, including finding unique elements in an array using bitwise techniques.

Linear Search Algorithm

In this module, we will introduce the linear search algorithm, a fundamental technique for searching through data. You will learn how to apply it to arrays, strings, and other data structures, and understand how it can be adapted to solve various search-related problems.

Binary Search Algorithm

In this module, we will introduce binary search, a highly efficient algorithm for searching sorted data. We will explore its various applications, including finding the ceiling and floor of numbers, as well as handling sorted arrays in both ascending and descending orders.
