What You Will Learn
Variables & Datatypes - I
Get started with Java by setting up your development environment. Learn how to write and run your first Java program, understand variables, and explore primitive data types.
Topics Covered:
- Installation of JDK – Set up Java Development Kit (JDK) to start coding in Java.
- The ‘Hello World’ on Command Prompt – Write and execute your first Java program using the command line.
- IDE - IntelliJ – Get familiar with IntelliJ, a powerful Integrated Development Environment (IDE) for Java.
- Variables – Learn how to declare and use variables to store data in Java.
- Primitive Data Types – Understand basic data types like int, char, float, and boolean.
Variables & Datatypes - II
Expand your knowledge of data types by exploring complex data structures. Learn how to take user input, perform operations, and use relational and logical operators.
Topics Covered:
- Arithmetic operations – Perform mathematical calculations like addition, subtraction, multiplication, and division.
- Taking user input in Java – Learn how to accept user input using the Scanner class.
- Strings and characters – Work with text data using Java’s String and char data types.
- Arrays – Store and manipulate multiple values efficiently using arrays.
- Relational operators – Compare values using operators like ==, !=, >, and <.
- Logical operators – Implement decision-making using AND, OR, and NOT operators.
- Comments in Java – Write comments to improve code readability and documentation.
- Errors while coding in Java – Identify and understand common coding errors.
- Debugging using the debugger tool – Use debugging tools to find and fix issues in your code.
Conditionals
Master conditional statements to control the flow of your Java programs. Learn to implement logic-based decision-making.
Topics Covered:
- Conditional statements – Use if, else if, and switch statements to control program execution.
- Loops – Implement loops to execute repetitive tasks efficiently.
- Functions – Learn how to define and use functions to improve code reusability.
Loops
Learn how loops help in automating repetitive tasks by executing a block of code multiple times based on a condition.
Topics Covered:
- Use loops to reduce the repetition of logic – Simplify code by reducing redundant statements.
- Implement while, do-while, and for loops – Learn different loop structures and when to use them.
- Use loops to solve problems – Apply loops to real-world programming scenarios.
Functions
Understand how functions help break down a program into smaller, manageable parts for better efficiency and reusability.
Topics Covered:
- Functions to make an efficient program – Write modular code by defining reusable functions.
- Use internal functions – Utilize built-in Java functions to simplify development.
- Handle errors – Implement error-handling techniques for robust applications.
