That's all abouthow to use BigInteger class in Java to store large numbers. We have seen how to calculate factorial and use the result in the BigInteger object. In conclusion, the BigInteger class in Java stands as a versatile and indispensable tool for handling large integer values, surpassin...

It is used when the integers involved are larger than the limit of thelongtype.For example, the factorial of 50 is30414093201713378043612608166064768844377641568960512000000000000.This value is too big for anint or longdata type to handle. It can only be stored in aBigIntegervariable. ...
