- use of preconditions; i.e. range-check the inputs so that overflow is impossible,
- doing each individual arithmetic operation using the next larger primitive integer type and explicitly checking for overflow, or.
- using BigInteger.
What is overflow error?
In general, a data type overflow error is when the data type used to store data was not large enough to hold the data. Furthermore, some data types can only store numbers up to a certain size. An overflow error will be produced, for example, if a data type is a single byte and the data to be stored is greater than 256.

Stack space is mainly used for storing order of method execution and local variables. Stack always stored blocks in LIFO order whereas heap memory used dynamic allocation for allocating and deallocating memory blocks.
