how to input a BigInteger type in java
<p>when I tried to get an input of type Integer, what I only needed to do was the code below.</p>

<pre><code>Scanner sc = new Scanner(System.in);
int N = sc.nextInt();
</code></pre>

<p>but when it comes to BigInteger, 
I don't know what to do. What can I do to read a BigInteger Type input from the user? </p>
