要在Java中的BigInteger中清除一点,请使用clearBit()
方法。它返回一个BigInteger,其值等于该BigInteger,并且清除了指定的位。
import java.math.*; public class BigIntegerDemo { public static void main(String[] args) { BigInteger one, two; one = new BigInteger("7"); two = one.clearBit(2); System.out.println("Result: " +two); } }
输出结果
Result: 3
让我们来看另一个例子。
import java.math.*; public class Demo { public static void main(String[] args) { BigInteger bi1, bi2; bi1 = new BigInteger("8"); bi2 = bi1.clearBit(2); String str = "Clearbit operation on " +bi1+ " at index 2 gives " +bi2; System.out.println( str ); } }
输出结果
Clearbit operation on 8 at index 2 gives 8
