===================== test.java =======================
import java.math.BigInteger;
import java.security.spec.*;

public class test  {
    public static void main (String[] args) { 
	EllipticCurve ec = new EllipticCurve(new testECField(), new BigInteger("4"), BigInteger.ONE);
        System.out.println("a = " + ec.getA() + "; b = " + ec.getB() + "; size = " + ec.getField().getFieldSize());
    } 
}
class testECField implements ECField {
    public int getFieldSize() {
	return 2;
    }
}
