Java 中的 BigInteger 或()方法
原文:https://www.geeksforgeeks.org/biginteger-or-method-in-java/
先决条件:大整数基础知识
Java . math . BigInteger . OR(BigInteger val)方法用于对两个 BigInteger 执行按位或运算。一个 BigInteger 传入参数,另一个调用函数。如果函数使用的任一个大整数为负数,则此方法返回负数。BigInteger 的 OR()方法对作为参数传递的当前 bigInteger 和 bigInteger 应用按位“或”运算。
语法:
public BigInteger or(BigInteger val)
参数:该方法接受一个大整数类型的参数值,并引用该大整数的“或”值。
返回值:该方法返回当前大整数与大整数值的按位或。
例:
Input: value1 = 2300 , value2 = 3400
Output: 3580
Explanation:
Binary of 2300 = 100011111100
Binary of 3400 = 110101001000
OR of 100011111100 and 110101001000 = 110111111100
Decimal of 110111111100 = 3580.
Input: value1 = 54298 , value2 = 64257
Output: 65307
下面程序举例说明 BigInteger 类的 or()方法:
/*
*Program Demonstrate or() 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 or() method to find (biginteger | val)
BigInteger biggerInteger = biginteger.or(val);
String result = "Result of OR operation between " + biginteger + " and "
+ val + " is " + biggerInteger;
// Print result
System.out.println(result);
}
}
输出:
Result of OR operation between 2300 and 3400 is 3580
