This repository was created to document and organize my progress in the 100 Days of Java Challenge, which started on September 8, 2024. The goal is to advance in learning the Java language, covering fundamentals, intermediate concepts, and more advanced topics throughout the journey.
Start: 08/09/2024 | Estimated End: 17/12/2024
Days 01 to 10
- General Planning: Set up a study plan and organized the repository.
- Java Setup: Installation of JDK and setup of the development environment.
- Java Documentation: Read "Overview" and "Getting Started" sections from the official Java documentation.
- Java History: Overview of Java's development and evolution.
- Course: Lessons 1 to 14 from the Java Marathon Challenge playlist.
- Primitive Data Types: Understanding
int,long,byte,short,float,double,boolean, andchar. - IDE Exploration: Basic navigation and features of IntelliJ IDEA.
- Book Addition: Started reading "Core Java Volume I - Fundamentals".
- Java Operators: Covered arithmetic, relational, logical, and assignment operators.
- Conditional Structures: Studied
if,else if, ternary operator, andswitchstatements. - Course: Lessons 15 to 26 from the Java Marathon Challenge playlist.
- String Manipulation: Learned the fundamentals of handling strings in Java.
- Exercises: Worked on conditional structures exercises.
- Loops: Practiced
while,do-while, andforloops, understanding their nuances and when to use each. - Flow Control: Applied the
breakandcontinuestatements to control the execution of loops. - Exercises: Reinforced knowledge with practical exercises focusing on loop structures.
- Arrays: Learned how to create, manipulate, and iterate over arrays using traditional loops and the
foreachloop. - Multidimensional Arrays: Explored how to work with multidimensional arrays to store and access data in matrix form.
- Object-Oriented Programming (OOP): Began learning about classes and objects in Java.
- OOP Benefits: Explored how OOP helps in organizing and structuring code efficiently.
- Access Modifiers: Learned about public, private, and protected, and how they control access to class members.
- Getters and Setters: Implemented getters and setters to control access to attributes while keeping data encapsulated.
- Object References: Deepened understanding of how classes define object behavior and how object references work in Java.
- Methods: Studied how methods operate within classes and their interactions.
- Cohesion: Learned about class cohesion, which is the practice of keeping each class focused on a single responsibility to promote code organization and avoid unnecessary repetition.
- Exercises: Completed exercises on class design and object references to reinforce the theoretical concepts.
- Methods: Continued studying methods, focusing on parameters and return values.
- Project Work: Reviewed the first 10 days by implementing a project based on learned concepts.
- BankAccount Project: Created a BankAccount class to simulate bank account operations such as deposits, withdrawals, and account status management.
- OOP Concepts Application: Practiced using classes and methods, reinforcing understanding of OOP principles.
- Project Structure: Organized the project into packages for better code management.
- Completed foundational Java concepts, including data types, operators, control structures, and OOP basics.
- Gained hands-on experience through practical exercises and a project, solidifying understanding of Object-Oriented Programming.

This repository reflects my commitment and progress in the 100 Days of Java Challenge. Throughout the days, I aimed to consolidate my knowledge and expand my skills in Java. Although I already had a foundation in Java from my university studies, this challenge provided me with an opportunity to deepen and update my understanding of both fundamental and advanced topics.
