First Code in Java Explained Practically Using CODE EDITOR- Beginners

JAVA is one of the best programming languages that helps most users build lots of applications and it is a language that has a multitude of applications across various industries.

Java is known to be used for the following:

1. Android App Development
2. Web Development
3. Enterprise Software
4. Desktop Application
5. Machine learning and data science as well
6. Scientific computing and embedded systems
7. Gaming
8. Network Programming
9. Education

The above are just a few of what Java can do and where Java can take you too. Meanwhile, the language is also known for its versatility, scalability and a large community of developers making it one of the popular choices for a wide range of applications and other features.

First code explained:

1             public class Main {

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

3                                           System.out.println(“We are the best in programming”);

4                            }

5             }

Break Down

Line1

public class Main {

This line is known to be used or to declare a new Java class name, that is Main. However, the public access modifier means that this class can be accessed from anywhere in the program.

In Java, a class is known to be a blueprint for creating objects, and also, it’s also a fundamental concept in object-oriented programming.

Line2

Note that this line public static void main(String)[ ] args) { is known to be used to declare the main method, which is the entry point of the entire program. In addition, the public access modifier means that this method can also be accessed anywhere in the written program or application.

The static keyword means that this method can be allowed without creating an instance of the class.

Also, the void keyword means that the method does not return a value.

main method is a special method in Java programming that is called when the program starts.

The String [ ] args is known to be called a parameter, an array of strings that represents the command line arguments passed to the entire program.

Line3

System.out.println(“We are the best in programming”);

This particular line prints out the (we are the best in programming to the console). In addition, it is automatically followed by a new character.

The system.out is known in Java programming as an object that represents the console output stream, and thus the println is a method that prints the entire argument to the console.

Note that the string ” We are the best in programming is the argument passed to the println method.

Tips:

In short, this Java program defines a Main class with a main method that prints out We are the best in programming” to the entire console when run.
