- public static void main(String[] args) Java main method is the entry point of any java program. Its syntax is always public static void main(String[] args) . You can only change the name of String array argument, for example you can change args to myStringArgs .
Can we execute a java program without main method?
Yes, we can execute a java program without a main method by using a static block.
A static block in Java is a group of statements that gets executed only once when the class is loaded into the memory by ClassLoader, It is also known as a static initialization block, and it goes into the stack memory.

What does "public static void main" stand for? Nowadays the answer should be: for an outdated Java version. Just "main" is enough from Java 21 onwards.
Except most programs or companies don't use Java 21
Public is an access specifier right???
They both are same.
@@samikshakamble105 ok thanks 😊
Yes. Public, private and protected all specify the access. Public just allows us to acces it across the entire program
Thank you
👍🏻👍🏻

We can run the program with out any main method we can possible to get the output by using static block in the jdk version 1.6v until small problem is we will get runtime exception saying so such method : main
In 1.7v if the main method is available or not main method we will get runtime exception saying can you define main method as public static void main(String[] args) first JVM will checks where the main method is available are not
No such main method
bhaii yo main hota he na Main nhe first letter of method in java is small

Static variable creates intimiate relationship with var/method to the Class class Object
Can you elaborate about static, I asked chat gpt it says it is used to access from outside class without any instances
@@Grehan-cf8rt no brother... the static variables/method got bind up with class class object and instance level var/method with the instances we create with new keyword... that's the difference nothing more than that...
that's why we can call static members with class name..
on the other hand we call instance var/method using the instances
@@Grehan-cf8rt don't ask these fundamental wuestions from chatGPT... prefer tackoverflow, javatpoint,geeksForGekks
@@Grehan-cf8rt in case of static we don't need to create obj of class. & if there are two different classes then we should use className to access the method.. Out side the class. If a single class then we can access method directly like this : eg: display () ;
class Test {
static void display () {
sop(”hii”) ;
}
public static void main(String[] args)
{
display () ;
}
}
this is literally the first thing you learn going into java

Ye kya example de diya
I’m just saying tho. I only know what the main method does but doesn’t know about its definition. Like I only know it’s like the core that calls on the other methods. Is this normal of me? Or I’m suppose to know it.
main should be written in small case
Work
The parentheses are supposed to be around the method parameters lol
So nice sir but this voice are not easily understood
Great
No they don't ask such questions in Job Interview

Whats the purpose of string [] args?
Idk, all I know is it's a required parameter, a String array to be precise.
fun fact tho, it doesn't necessarily needed to be "args"
and that you can call
main( _arrayArgument[]_ );
within other methods, including itself.
The purpose of string[] args is we can't using scanner class and input class we can give the user input from the console by using command line argument the following command is to first you complie the java program is "javac file.java " and next then we should go for next step is to execute the java program is "java filename" for example javac Hello.java and next java Hello command line arguments are starting here java Hello J A V A the output will be displayed in console line by line J next line A .......❤❤❤❤❤ plz reply it will work's try
Gi
j
"How I make 20k a month with Shorts and AI"
sting args??
It is a command line argument for example if you not using scanner class or another input method we can user input from the program by using these command is javac filename.java the the to execute the program the command is java filename the input is H E L L O it will execute line by line ❤❤❤❤
Spelling mistakes
who ask this at interview ? 😂
