Answer 1

The args.length value is the number of items in the args array.

If you pass no command-line arguments, you will always get "There are 0 command line arguments".

thats why you checking

if (args.length > 0) 

But try running the program like this: java PrintArgs hello my name is mikki2 The words after java PrintArgs are called command line arguments because they are arguments passed to your program from the command line
