Using command line arguments

Using command line arguments

• The args parameter of the main() method stores the command line arguments passed to the program.

• Command line arguments are information provided after the program name on the command line during execution.

• These arguments are stored as strings in a String array passed to main().

• The following example demonstrates how to display all command-line arguments provided to the program.

• Output below:
  There are 3 command-line arguments.
  They are:
  arg[0]: one
  arg[1]: two
  arg[2]: three

• Command line arguments are stored in an array, with the first argument at index 0, the second at index 1, and so on.

• The following example illustrates how to use command-line arguments to receive a person's name.

• The program searches for this name in a two-dimensional array of strings.

• If the name is found, the program will display the corresponding phone number.
