String index out of bounds? (Java, substring loop)

Question

This program I\'m making for a COSC course isn\'t compiling right, I keep getting the error:

Exception in thread \"main\" java.lang.StringIndexOutOfBoundsException:

Answer 1

Removing the equal sign should fix that.

while (count < input.length()) {

and since you want to get a single character, you should do this:

substr(count,1)

because the 2nd parameter is actually length, not index.
