java.math.BigInteger.and(BigInteger val) 返回一個BigInteger,其值是 (this & val). 該方法返回一個負BigInteger的當且僅當這個和Val均為負。
以下是java.math.BigInteger.and()方法宣告
public BigInteger and(BigInteger val)
val - 此BigInteger進行與運算的值
此方法返回BigIntger物件的值, this & val
NA
下面的例子顯示math.BigInteger.and()方法的用法
package com.yiibai; import java.math.*; public class BigIntegerDemo { public static void main(String[] args) { // create 3 BigInteger objects BigInteger bi1, bi2, bi3; // assign values to bi1, bi2 bi1 = new BigInteger("6"); //110 bi2 = new BigInteger("3"); //011 // perform and operation on bi1 using bi2 bi3 = bi1.and(bi2); String str = "Result of and operation is " +bi3;; // print bi3 value System.out.println( str ); } }
讓我們編譯和執行上面的程式,這將產生以下結果:
Result of and operation is 2
