Section 3: Decision Making
This section focuses on decision-making structures in Java, such as if-else statements, switch-case programs, and nested conditions. You’ll understand how to implement conditional logic in Java programs and learn to use Java’s looping and control system effectively for decision-making.
Section 4: Numbers Class
Explore Java's Number class and its various methods. You will understand how to manipulate numbers using Java’s built-in methods, such as the Math class, to perform mathematical operations. This section also discusses number conversions and provides practical examples for better clarity.
Section 5: Character Class
Dive into the Character class and learn how to work with escape sequences, character methods, and how characters are handled in Java. This section also covers the use of Java's built-in Character class methods to manage character data effectively.
Section 6: String Class
Java strings are a crucial data type for handling text. In this section, you'll explore Java's String class, learn how to manipulate strings (e.g., reversing, comparing, and formatting), and handle common string operations efficiently.
Section 7: Arrays
Arrays are one of the most basic data structures in Java. This section covers array fundamentals, iteration techniques, and methods to pass arrays to functions. You will also learn about array sorting and handling arrays in Java for efficient data storage and access.
Section 8: Advanced Arrays
Dive deeper into arrays by learning advanced topics like passing arrays to methods, sorting arrays, and working with the Array class. You’ll also get a better understanding of how Java handles dates and times, and how to convert between them.
Section 9: Regular Expressions
Java regular expressions allow you to manipulate and match patterns in strings. In this section, you'll learn how to use regular expressions to match patterns, replace text, and validate inputs effectively.
Section 10: Methods and File IO
Learn about Java methods, file input/output (I/O), and exception handling. You will cover different types of methods, practical sessions on handling files, and work with streams for reading and writing data in files.
Section 11: OOPS Concepts
Object-Oriented Programming (OOP) is essential for writing efficient Java code. This section will guide you through concepts like inheritance, abstraction, encapsulation, and interfaces. You’ll also explore the use of the super keyword and learn how Java implements virtual methods and method overriding.
