    Default Please help me with this

    This is what I have to program:

    Write an application that creates and prints a random phone number of the form XXX - XXX - XXXX. Include the dashes in the output. Do not let the first three digits contain an 8 or 9, make sure that the second set of three digits is not greater than 742.

    Im so confused on how to start this.
    Please help me

    Here's some info to point you in the right direction. You need random numbers...use Math.random() or the Random class to achieve this. You can use the modulus operator to get the number of digits you'd like if necessary. Then do some if statements to make sure the numbers validate. If you don't know what any of this terminology means, google them and you will find more than enough information. Hope this helps
