Use the java.math.BigInteger class to store your numbers and compare them.

You could turn them both into Strings and compare them with their equals() method.

Hi , I have a similar problem to this currently i got around it by loading the digits straight into a char array and then compare the outputs and it works but il rather have a simpler solution.

I tried the above methods suggesting to convert it to string, but that would only be possible if i can store the value as something initially i.e. long  num = 40 digits.

Just a question for InteractiveMind  how many digits can you assign to BigInteger.
sorry in advance if im not allowed to ask a counter question here

thanks

I am fairly sure BigInterger is designed to hold unlimited amount of digitis. It should just keep allocating more memory.
