Why is it not throwing exceptions when I enter Zeros? Help me correct the mistake

Question

Write a program that prompts the user to enter a length in feet and inches and outputs the equivalent length in centimetres. If the user enters a negative number or a nondigital number, throw and handle an appropriate exception and prompt the user to enter another set of numbers.

Answer 1

You have written && inches, that is the problem.

Because this means: If feet<=0 AND inches !=0.

So if you enter 0 for feet and something for inches, you do get your error.

But if both are zero, you don't get the error.

For clarity, once again:

if(inches)

means the same as:

if(inches != 0)
