Command Line Arguments

• A Java application can be passed string arguments when it is executed.

• These are called command line arguments and allow your programs to receive simple input from whomever is executing your program.

• When you execute your application, you can pass in values by adding them to the end of the java command:

  	java MyFamily Pippi
  

• Each separate string is an argument, so if you want to pass in a phrase, (i.e. "Pippi the dog") you will need to quote it.

• In your program, the array named args has the passed-in arguments.

  (Remember static void main(String args[])?)

• To access these values, you just access the array.

• The first argument is in args[0].

• Unlike Linux, C, and C++, the first element in the array does not contain the name of the program.
