math. BigInteger. add(BigInteger val) is used to calculate the Arithmetic sum of two BigIntegers. This method is used to find arithmetic addition of large numbers of range much greater than the range of biggest data type double of java without compromising with the precision of the result.

## How do you add two big numbers without using BigInteger in Java?

Take the last digits(Conversely reverse the strings and take the first digits) of the string. **Add them by temporally converting to integers**. Maintain two variables ‘sum’ and ‘carry’. Print(or store) the last digit of the ‘sum’ and the second last digit(0 in-case there is none) shall be the ‘carry’.

## What is big integer in Java?

Big Integer class **extends Number and implements Comparable interface**. It provides analogues to all of Java’s primitive integer operators and all methods from java. lang. … This method returns a BigInteger whose value is equal to this BigInteger whose designated bit is cleared.

## How do you multiply big integers in Java?

**multiply(BigInteger val)** is used to calculate the multiplication of two BigIntegers. As BigInteger class internally uses an array of integers for processing, the operation on an object of BigInteger are not as fast as on primitives.

## How do I convert a string to an int?
