Integer number too large

My objective is to continuously decrement of the given large number till a certain value(say K).

Integer number too large

the reason why it's giving an error is because the type that you've passed into the argument of the valueOf(...) is an int (this is the default type unless you specify otherwise) which has a limit, and you've exceeded this limit hence the error.

BigInteger l = BigInteger.valueOf(111111111111111110); // argument is int, so it will give a compiler error

use a long argument instead.

BigInteger value = BigInteger.valueOf(111111111111111110L);

or use a string argument.

BigInteger value = new BigInteger("111111111111111110");
