This course is your detailed guide to the fundamentals of the Java programming language. This course will get you on the fast track to becoming a proficient and modern Java developer.

In this course, you will start by covering different programming paradigms like object-oriented and procedural programming. You will then cover the fundamentals of programming in Java such as: objects and data types, variables, arrays, and conditional statements.

In the latter half of the course, you will cover iterative constructs, useful algorithms, and data structures. With over 100 problems, 11 quizzes, and 9 challenges, this course will get you prepared for a career in software development.

A Complete Guide to Java Programming

# Chapter's briefing 

In this chapter, we will learn about the array. We have seen before that a variable is a location in memory that has a name that contains a value. This value could be any data type, such as `int`. An array is also another kind of variable or a container object that holds a fixed number of values of a single type. Therefore, an array could be any data type, such as `int`, or `String`. We have used arrays before, in our last programs, unknowingly. Watch this code snippet below:

```java
public static void main(String[] args){}
```

In every program, this is the entry point; the `main` method has a parameter, which is an array of `String` type.


# Array in the `main()` method
In many Java programs, you will see two types of `main` methods:

1) `public static void main(String[] args){}`
2) `public static void main(String args[]){}`

In fact, in our previous examples, we have used the second type. From now on, we will be using the first one. 

Why? Any particular reason?

No. Java allows both. Java makes no difference between these two statements. However, in this chapter, we will find that declaration of an array by using the second one is discouraged in their official documentation. 

Logically, from now on, we will stick with the first one.



This lesson recalls how we're already familiar with the arrays along with the chapter's briefing.
