在BigInteger上实现andNot操作的Java程序
TheBigInteger.andNot(BigIntegerval)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-
示例
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-
示例
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
