BigInteger類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()方法將返回由2個元素組成的BigInteger數組，其中包含使用(this BigInteger)/(BigInteger val)計算得出的商數，然后返回使用(this BigInteger)％(BigInteger val)計算得出的余數。

• 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()方法是一個非靜態方法，只能通過類對象訪問，如果嘗試使用類名稱訪問該方法，則會收到錯誤消息。

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

  在計算余數時， divideAndRemainder()方法可能會引發異常。

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

  ArithmeticException：當給定參數的值為0時，可能引發此異常。

Syntax:

句法：

    public BigInteger[] divideAndRemainder(BigInteger val);

Parameter(s):

參數：

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

  BigInteger val –表示該BigInteger被除以并生成余數的值。

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).

此方法的返回類型為BigInteger [] ，它返回兩個由BigInteger類型組成的元素的BigInteger數組，商是使用(this BigInteger)/(BigInteger val)計算的，余數是使用(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

輸出量

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