BigInteger類(lèi)nextProbablePrime()方法 (BigInteger Class nextProbablePrime() method)

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

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

• nextProbablePrime() method is used to get the next probable prime number that should be higher than this BigInteger and there is a limit of composite number that should not exceed 2 pow(-100).

  nextProbablePrime()方法用于獲取下一個(gè)可能大于此BigInteger的下一個(gè)素?cái)?shù)，并且合成數(shù)的限制不得超過(guò)2 pow(-100)。

• nextProbablePrime() 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.

  nextProbablePrime()方法是一種非靜態(tài)方法，僅可通過(guò)類(lèi)對(duì)象訪問(wèn)，如果嘗試使用類(lèi)名訪問(wèn)該方法，則會(huì)收到錯(cuò)誤消息。

• nextProbablePrime() method may throw an exception at the time of returning the next probable prime number.

  nextProbablePrime()方法在返回下一個(gè)可能的質(zhì)數(shù)時(shí)可能會(huì)引發(fā)異常。

  ArithmeticException: This exception may throw when the value of this BigInteger is negative.

  ArithmeticException ：如果此BigInteger的值為負(fù)，則可能引發(fā)此異常。

Syntax:

句法：

public BigInteger nextProbablePrime();

Parameter(s):

參數(shù)：

• None

  沒(méi)有

Return value:

返回值：

The return type of this method is BigInteger, it returns BigInteger that holds the value larger than this BigInteger and it is probably prime.

此方法的返回類(lèi)型為BigInteger ，它返回的BigInteger持有的值大于此BigInteger，并且它可能是素?cái)?shù)。

Example:

例：

// Java program to demonstrate the example // of BigInteger nextProbablePrime() method of BigIntegerimport java.math.*;public class NextProbablePrimeOfBI {public static void main(String args[]) {// Initialize two variables str1 and str2String str1 = "13";String str2 = "6";// Initialize two BigInteger objects BigInteger b_int1 = new BigInteger(str1);BigInteger b_int2 = new BigInteger(str2);// returns the next prime number// of this BigInteger b_int1 so the value of// this BigInteger is 13 then the next prime// after 13 is 17BigInteger next_prime = b_int1.nextProbablePrime();System.out.println("b_int1: " + b_int1);System.out.println("b_int1.nextProbablePrime(): " + next_prime);System.out.println();// returns the next prime number// of this BigInteger b_int2 so the value of// this BigInteger is 6 then the next prime// after 6 is 7next_prime = b_int2.nextProbablePrime();System.out.println("b_int2: " + b_int2);System.out.println("b_int2.nextProbablePrime(): " + next_prime);} }

Output

輸出量

b_int1: 13 b_int1.nextProbablePrime(): 17b_int2: 6 b_int2.nextProbablePrime(): 7
