public class BigIntegerExam {
 public static void main(String[] args) {
  BigInteger bi1 = new BigInteger("0");
  BigInteger bi2 = new BigInteger("10");
  BigInteger bi3 = new BigInteger("-10");

  // assign signum results of bi1, bi2, bi3 to i1, i2, i3
  int i1 = bi1.signum();
  int i2 = bi2.signum();
  int i3 = bi3.signum();

  // print i1, i2, i3 values
  System.out.println(i1);
  System.out.println(i2);
  System.out.println(i3);
 }
