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"

If this is in reference to the "String[] args" passed as a parameter to the "public void static main()" method, then it refers to the list of arguments passed to the class when it is called. Eg: When the following command is executed "java abc xxx yyy" then in the main method of the abc.java, the first parameter of args i.e. args[0] would have "xxx" and the second parameter of args i.e. args[1] would have "yyy". Referring to the 3rd or any other higher element would throw a "IndexOutOfBounds" exception

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.

What is the argument of main()method?

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 info2In this example, "info1" and "info2" will be received by the main method, in the args[] array.


Why in java string args is passed in main method?

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

Can you have two mains in java?

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....

What is the use of main method in java?

The Main method is the method in which execution to any java program begins. A main method declaration looks as follows: public static void main(String args[]){ } The method is public because it be accessible to the JVM to begin execution of the program. It is Static because it be available for execution without an object instance. you may know that you need an object instance to invoke any method. So you cannot begin execution of a class without its object if the main method was not static. It returns only a void because, once the main method execution is over, the program terminates. So there can be no data that can be returned by the Main method The last parameter is String args[]. This is used to signify that the user may opt to enter parameters to the java program at command line. We can use both String[] args or String args[]. The Java compiler would accept both forms.
