By running a program at a command line we can pass some arguments to it. These arguments are called command line arguments. This array is used to hold the command line from the command prompt

In the main method,the String array args refers to the arguments that the program may require before starting. In many cases you may want the program to take some values as input for processing. this string array is for that purpose. It is needed to configure the application to run a particular way or provide it with some piece of information it needs.
