can anyone show an example program using command line arguments ,utilising the string args[] in main()

Answer 1

Command line argument is for command line input. I use CMD. I can't help you with netbeans since I don't use it. Error you're getting is indicating that you're not putting in any argument to fill the args array. I can't answer whether or not netbeans allows you to put in command line arguments.

Answer 2

class ArgumentTest{
public static void main(String[] args){
System.out.println(args[0]);
}
}

javac ArgumentTest.java
java ArgumentTest "hello"

Answer 3

I am trying to run in netbeans it's showing array index out of bound error. :(
