Java 中的 BigInteger 和()方法
原文:https://www . geesforgeks . org/big integer-and-method-in-Java/
Java . math . BigInteger . AND(BigInteger val)方法返回一个 BigInteger，其值是两个 BigInteger 的按位“与”。如果两个大整数都是负数，则此方法返回负数。and()方法对作为参数传递的当前大整数和大整数应用按位“与”运算。 语法:
public BigInteger and(BigInteger val)
参数:该方法接受一个大整数类型的参数值，并引用要与当前大整数“与”的值。 返回值:该方法返回两个大整数的按位“与”的值。 示例:
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
下面的程序用来说明 BigInteger 的 and()方法。
Java 语言(一种计算机语言，尤用于创建网站)
/*
*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);
}
}
Output:
Result of AND operation between 2300 and 3400 is 2120
