∙ 14y agoThe main method in Java has a string array parameter that contains the arguments passed in.
Example:
import java.util.Arrays;
public class A {
public static void main(String[] args){System.out.println(Arrays.toString(args));}
}

What is java command?
A Java application can accept any number of arguments from the command line. This allows the user to specify configuration information when the application is launched.The user enters command-line arguments when invoking the application and specifies them after the name of the class to be run.
Can a Java program use one or more command line arguments?
Command line arguments in Java are, as with most programming languages, a way to give information to a program at the point of invoking (starting to run) that program. The information is given in the form of a text string. Command line arguments are accessible in a Java program as an array of String objects passed into the program's "main" method. Unlike some programming languages (such as C/C++), where the command used to invoke the program is passed into the first array location (index 0) and the arguments subsequently, in Java the first argument occupies index 0. Command line arguments are a useful way of gathering information from the user when it is likely will know the information at the start of the program. For example, a Java application might copy a file from myFile.txt to myNewFile.txt by running the command "java CopyUtil myFile.txt myNewFile.txt". It is useful to allow such information to be passed in via command line arguments to make the program more scriptable: in other words, more conducive to scripted invocation, through a Desktop shortcut, through a batch file, through a shell script, etc.

What is a command argument?

How do you write a function in Turbo C that can run the program without rerunning the whole program?
The execution path of a program can only be affected by the program input. That is, if you change the input, you can alter the way the program behaves (just as changing the arguments to a function can alter the behaviour of the function). Typically you will alter the input via the command line, but you can also alter the input at any time during program execution. Redirecting input via the command line can be achieved by extracting the input from a file (via std::cin) or by implementing command line switches in your main function, or through a combination of the two.
