TheBigInteger.andNot(BigInteger val)返回一个BigInteger,其值为(this&〜val)。此方法等效于and(val.not()),是为了方便进行掩码操作。当且仅当此值为负且val为正时,此方法才返回负的BigInteger。在这里,“ val”是要用此BigInteger进行补充和与的值。
以下是一个例子-
import java.math.*;
public class Demo {
public static void main(String[] args) {
BigInteger one, two, three;
one = new BigInteger("12");
two = new BigInteger("6");
three = one.andNot(two);
System.out.println("Result (andNot operation): " +three);
}
}输出结果
Result (andNot operation): 8
让我们看另一个例子-
import java.math.*;
public class Demo {
public static void main(String[] args) {
BigInteger bi1, bi2, bi3;
bi1 = new BigInteger("9");
bi2 = new BigInteger("2");
bi3 = bi1.andNot(bi2);
String str = "Result of andNot operation is " +bi3;;
System.out.println( str );
}
}输出结果
Result of andNot operation is 9
