Question

For this assignment you are going to write code for the following ONE class called:

Print_n_numbers

Here are the specifications for the class: Make sure the class Print_n_numbers has a default constructor, i.e. it is possible to create an object of the class by executing:

new Print_n_numbers()

The class has only one method: print.

Specs for the method:

name: print arguments: one int, called n. returns: nothing what it does: it prints the numbers 1, 2, 3 ... n

if the number is 0 or negative the method print prints:

bad number

You can use the following OPTIONAL (i.e. whether you write it or not it will not affect the tests) main method:

public static void main(String[] aa){ Print_n_numbers ss = new Print_n_numbers(); Scanner scan = new Scanner(System.in); int ii = 0; while (ii != -1){ System.out.print("please enter a non-zero number (-1 to end): "); ii = scan.nextInt(); System.out.println("the following is the output of ss.print(" + ii + "):\n"); ss.print(ii); } }

If you have this main method, then you can type: Note: in the following example what the user would enter is shown in bold face. Otherwise it is the output of the program.

java Print_n_numbers please enter a non-zero number: 0 the following is the output of ss.print(0):

bad number

please enter a non-zero number: -2 the following is the output of ss.print(-2):

bad number

please enter a non-zero number: 1 the following is the output of ss.print(1):

1

please enter a non-zero number: 2 the following is the output of ss.print(2):

1, 2

please enter a non-zero number: 5 the following is the output of ss.print(5):

1, 2, 3, 4, 5

please enter a non-zero number: 10 the following is the output of ss.print(10):

1, 2, 3, 4, 5, 6, 7, 8, 9, 10

please enter a non-zero number: 30 the following is the output of ss.print(30):

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30

please enter a non-zero number: -1 the following is the output of ss.print(-1):

bad number
