JAVA Basics 4: Java Command Line Arguments

This class demonstrates how command line arguments are passed in Java. Arguments are passed as a String array to the main method of a class. The first element (element 0) is the first argument passed not the name of the class.

Source Code
An example that prints in the command line arguments passed into the class when executed.
public class ReadArgs
{
       public static final void main(String args[])
       {
                for (int i=0;i<args.length;++i)
                {
                         System.out.println( args[i] );
                }
        }
} 

Sample Run

With the following command line, the output shown is produced.

java ReadArgs zero one two three


Output:

The following command line arguments were passed:
arg[0]: zero
arg[1]: one
arg[2]: two
arg[3]: three
