Command Line Arguments in Java

Most of the time, developers write programs that interact with the user through standard input and output streams at run-time. But standard inputs and outputs do not solve all the requirements of the users. Sometimes, we need to pass data at the time of entering a run command for the program. The data which are passed to a program in this way are known as command-line arguments.

Note that the command line arguments are passed to the main method as arguments.

CommandLineArgs.java

public class CommandLineArgs { public static void main(String[] args) { int counter = 0; double sum = 0.0; for (String s : args) { sum += Double.parseDouble(s); counter++; } System.out.println("The sum of elements is : " + sum); System.out.println("Average of the elements is : " + sum / counter); } }
