Hello !

I think this code will do what you want:

public String ab1()
{
  int n1=1000 ,e1=1000;
  BigInteger s1 = new BigInteger(97+"");
  BigInteger bi;
  bi = s1.modPow(new BigInteger(e1+""), new BigInteger(n1+""));
  return bi+"";
}

You must import java.math.*

Your problem was that you exceeded the range of double and int.

+"" is equal to .toString()

Greetings,
