Java BigInteger and()用法及代码示例

java.math.BigInteger.and(BigInteger val)方法返回一个BigInteger，其值为两个BigInteger的bitwise-AND。如果两个BigIntegers均为负数，则此方法返回负数。 and()方法对作为参数传递的当前bigInteger和bigInteger应用bitwise-AND操作。

用法:

public BigInteger and(BigInteger val)

参数：该方法接受BigInteger类型的一个参数val，表示要与当前BigInteger进行“与”运算的值。

返回值：该方法返回两个BigIntegeres的bitwise-AND的值。

例子：

Input: value1 = 2300, value2 = 3400
Output: 2120
Explanation:
Binary of 2300 = 100011111100
Binary of 3400 = 110101001000
AND of 100011111100 and 110101001000 = 100001001000
Decimal of 100001001000 = 2120.

Input: value1 = 432045, value2 = 321076
Output: 296484

下面的程序用于说明BigInteger的and()方法。

/* 
*Program Demonstrate and() method of BigInteger  
*/
import java.math.*; 
  
public class GFG { 
  
    public static void main(String[] args) 
    { 
  
        // Creates 2 BigInteger objects 
        BigInteger biginteger = new BigInteger("2300"); 
        BigInteger val = new BigInteger("3400"); 
  
        // Call and() method to find this & val 
        BigInteger biggerInteger = biginteger.and(val); 
  
        String result = "Result of AND operation between " + biginteger + " and "
                        + val + " is " + biggerInteger; 
  
        // Print the result 
        System.out.println(result); 
    } 
}

输出：

Result of AND operation between 2300 and 3400 is 2120
