Example Java palindrome checker results. When this program runs, it returns: true for sitonapanotis; false for nine; true for amanaplanacanalpaname; Other Java Strings to palindrome check. Here are 10 ...

I have seen recursion code implode on itself on the JVM before. In this case, we caught the annoying stack overflow problem before it went into production and I had to work a good number of hours ...
