[Bob Holland]

hi again, what is the syntax to chech that a string variable has the right ammount of charcters, i think its something like


if (variable lenght < 0)

Yes its something like that. The JavaDocs for the String class will tell you for certain.

Did you look at the method length ?
length() Returns the length of this string.

if (variable.length() < 13 )

Remember that String is a class, so when you find a method name to use with it, the syntax is exactly the same as calling a method on any other class.

Keep Coding!
