how to input a BigInteger type in java

Question

when I tried to get an input of type Integer, what I only needed to do was the code below.

Scanner sc = new Scanner(System.in);
int N = sc.nextInt();
         


        

Answer 1

Scanner sc = new Scanner(System.in);
BigInteger b = new BigInteger(sc.next());

There is also:

BigInteger b = sc.nextBigInteger();
