1. Command Line Argument2. Simple example of command-line
argument3. Example of command-line argument that prints all the
values
The command-line argument is an argument passed at the time of
running the javaprogram. The argument can be received in the
program and used as an input. So, itprovides an convenient way to
check out the behaviour of the program on differentvalues. You can
pass N numbers of arguments from the command prompt.Simple example
of command-line argumentIn this example, we are receiving only one
argument and printing it. For running thisprogram, you must pass at
least one argument from the command prompt.
class A{public static void main(String args[]){
System.out.println("first argument is: "+args[0]);
}}
compile by > javac A.java
run by > java A sonoo
Output:first argument is: sonoo
Example of command-line argument that prints all the valuesIn
this example, we are printing all the arguments passed from the
command-line. Forthis purpose, we have traversed the array using
for loop.
