BigInteger类divideAndRemainder()方法 (BigInteger Class divideAndRemainder() method)

• divideAndRemainder() method is available in java.math package.

  splitAndRemainder()方法在java.math包中可用。

• divideAndRemainder() method returns BigInteger array of 2 elements that contain quotient that is calculated by using (this BigInteger)/(BigInteger val) followed by the remainder that is calculated by using (this BigInteger) % (BigInteger val).

  splitAndRemainder()方法将返回由2个元素组成的BigInteger数组，其中包含使用(this BigInteger)/(BigInteger val)计算得出的商数，然后返回使用(this BigInteger)％(BigInteger val)计算得出的余数。

• divideAndRemainder() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.

  splitAndRemainder()方法是一个非静态方法，只能通过类对象访问，如果尝试使用类名称访问该方法，则会收到错误消息。

• divideAndRemainder() method may throw an exception at the time of calculating the remainder.

  在计算余数时， divideAndRemainder()方法可能会引发异常。

  ArithmeticException: This exception may throw when the given parameter holds value 0.

  ArithmeticException：当给定参数的值为0时，可能引发此异常。

Syntax:

句法：

    public BigInteger[] divideAndRemainder(BigInteger val);

Parameter(s):

参数：

• BigInteger val – represents the value by which this BigInteger is to be divided and generate remainder.

  BigInteger val –表示该BigInteger被除以并生成余数的值。

Return value:

返回值：

The return type of this method is BigInteger[], it returns an array of BigInteger of two element of "BigInteger" type and the quotient is calculated by using (this BigInteger)/ (BigInteger val) and the remainder is calculated by using (this BigInteger) % (BigInteger val).

此方法的返回类型为BigInteger [] ，它返回两个由BigInteger类型组成的元素的BigInteger数组，商是使用(this BigInteger)/(BigInteger val)计算的，余数是使用(this BigInteger)％(BigInteger val)。

Example:

例：

// Java program to demonstrate the example 
// of divideAndRemainder(BigInteger val)  method of BigInteger
import java.math.*;
public class DivideAndRemainderOfBI {
public static void main(String args[]) {
// Initialize two variables divi, divisr
String divi = "120";
String divisr = "4";
// Initialize two BigInteger objects 
BigInteger b_int1 = new BigInteger(divi);
BigInteger b_int2 = new BigInteger(divisr);
// Display b_int1 and b_int2
System.out.println("b_int1: " + b_int1);
System.out.println("b_int2: " + b_int2);
System.out.println("divideAndRemainder(BigInteger): ");
// divides this BigInteger (b_int1) by the
// given BigInteger (b_int2) and return the BigInteger[]
// of two values (Quotient, Remainder)
BigInteger[] div_rem = b_int1.divideAndRemainder(b_int2);
System.out.println("Quotient div_rem[0]: " + div_rem[0]);
System.out.println("Remainder div_rem[1]: " + div_rem[1]);
}
}

Output

输出量

b_int1: 120
b_int2: 4
divideAndRemainder(BigInteger): 
Quotient div_rem[0]: 30
Remainder div_rem[1]: 0
