Parameters used in First Java Program

First Java Program

class :- keyword is used to declare a class in Java.

public:- keyword is an access modifier that represents visibility. It means it is visible to all.

static :- is a keyword. If we declare any method as static, it is known as the static method. The core advantage of the static method is that there is no need to create an object to invoke the static method. The main() method is executed by the JVM, so it doesn't require creating an object to invoke the main() method. So, it saves memory.

void:- is the return type of the method. It means it doesn't return any value.

main:- represents the starting point of the program.

String[]:- args or String args[] is used for command line argument. We will discuss it in coming section.
