In Java, the main() method is typically written something like this:public static void main(String [ ] args)
The argument is what is in parentheses, in this case: "String [] args". I believe this can also be written as "String args[]". It refers to parameters received by the Java program from the command line. That is, the user can write, for example:
java MyClass info1 info2
In this example, "info1" and "info2" will be received by the main method, in the args[] array.
If you're referring to "args" in the line: "public static void main(String args[])", then it is the name of the array that holds the command line arguments. So, if you called your java program (called myJavaProgram) from the command line using the following line: java myJavaProgram Hello World "These are args" Then args would have the following values stored in it: args[0] = "Hello" args[1] = "World" args[2] = "These are args" If you called your program from the command line like this: java myJavaProgram Different Args then args would contain args[0] = "Different" args[1] = "Args"

String[] args means an array of sequence of characters (Strings) that are passed to the "main" function. This happens when a program is executed. Example when you execute a Java program via the command line: java MyProgram This is just a test. Therefore, the array will store: ["This", "is", "just", "a", "test"] To learn more about data science please visit- Learnbay.co

The String[] args parameter is an array of Strings passed as parameters when you are running your application through command line in the OS. The java -jar command will pass your Strings update and notify to your public static void main() method. To learn more about data science please visit- Learnbay.co
import javax.swing.JOptionPane; public static void main (String[]args){
class SecondProgram { public static void main(String args[]) { System.out.println(/welcome/to/mist } }
Yes... We can have more than one main in JAVA... Just make the only one main method as public and other as default access specifier.... public class Test { public static void main(String args[]) { } } class Test1 { public static void main(String args[]) { } } class Test2 { public static void main(String args[]) { } } Just copy the above code and try.... Have fun in learning... :-) :) :-)
public class Hello { public static void main (String args[]) { System.out.println("Hello World"); } }
public class Hello{public static void main(String [] args){System.out.println("Hello");}}
public class HappyBirthday{ public static void main (String [] args){ System.out.println("Happy Birthday!"); } }
