Question

You should have a single command-line argument representing number of objects you must generate for the user.

Just wanted to make sure that I got this one right.

Does this mean we should pass the params to the main method?

Answer 1

Your Java program needs to be invoked from the command prompt, say for example, MyProgram.java is a source file which contains the main() method, you compile this using the javac compiler by doing javac MyProgram.java at the command prompt to get the MyProgram.class file. This .class file is then invoked by doing java MyProgram at the command prompt to run your program.

What you need to do here is pass parameters to the main() method when you run your program simply by doing java MyProgram <your params go here>
