When I said, 'Where ... refers to the code after the line String s = inFile.readLine();' I meant all of the code. A loop will allow for a set of instructions to be executed 0, 1 or more times. If all you want to repeat is reading the data from the file, then that leaves you with only processing the last line of the file.

You need to read in the data and process it and that's what needs to be repeated and thus placed in a loop.

Anyway, what do you mean by, 'at the start of my boolean?' Please use the [code=java] so line numbers appear. That way you can tell us which line the error occurred. The expression in the while loop is not incorrect and would compile.

Regardless, by looking at your code I can see that you're missing some braces. Particularly, you don't close the for loop nor do you close the main method. This is why you're getting the error.

First of all:
Next time post what kind of error you get and where you get it so we wouldn't have to search the entire code for the error.

And second:

This:

should be:

And you don't have to use recursion to test whether something is a palindrome or not.
