Java

Java is a high-level, object-oriented language known for its portability and reliability. Mastering Java is key for developers to build scalable, secure software efficiently.

In this course, you will start by mastering the art of problem-solving with simple Java programs, such as the Bottle Filling example. You will learn how to structure your solutions, create execution sheets, and enhance your problem-solving abilities through practical exercises and quizzes. Progressing further, you will learn decision-making and branching in Java, understanding flowcharts, conditional expressions, and their application. You will also learn about Java basics, including the first Java program, fundamentals, conditional statements, and error categories, followed by in-depth lessons on working with Java strings and arrays. 

By the end of this course, you will have a solid understanding of Java programming fundamentals and the ability to solve real-world problems using Java.

## Methods
We can divide a program into procedural components or modules called **methods** in Java. We are already familiar with the `main()` method. Methods can be copied and reused in a programming technique called a **modular** or **procedural approach**, also known as the divide and conquer approach. We should always try to design methods that can be reused in other programs too.
