Java程序在BigInteger上实现NOT操作
BigInteger.not()方法返回一个BigInteger,其值为(〜this)。当且仅当此BigInteger为非负值时,此方法才返回负值。
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("6"); two = one.not(); System.out.println("Result (not operation): " +two); } }
输出结果
Result (not operation): -7
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, bi4; bi1 = new BigInteger("9"); bi2 = new BigInteger("-12"); bi3 = bi1.not(); bi4 = bi2.not(); String str1 = "Result of not operation on " + bi1 +" gives " +bi3; String str2 = "Result of not operation on " + bi2 +" gives " +bi4; System.out.println( str1 ); System.out.println( str2 ); } }
输出结果
Result of not operation on 9 gives -10 Result of not operation on -12 gives 11
