Addition of 256bit unsigned integers

[Chan Lee]

Hi friends,

I need a help.
Can anyone tell how to add two 256bit/512bit/1024bit unsigned integers in java?
(or)
Can anyone give some idea? please help me.

You can use BigInteger.
This supports addition and other operations of any precision integers.

Thank you Peter, i know that we can use BigIntegers concept. But, I'm unable to get any idea regarding this problem.

Look in the API documentation; it is really easy.

a 256-bit number is just a number. The BigInteger class has several constructors that take different objects. How is your number stored? Probably the simplest would be to convert it to a string and use that.

"budha",
may have missed that we have a policy on screen names here at JavaRanch. Basically, it must consist of a first name, a space, and a last name, and not be obviously fictitious. Since yours does not conform with it, please take a moment to change it, which you can do right here.
