nextgaussian

隨機類nextGaussian()方法 (Random Class nextGaussian() method)

• nextGaussian() method is available in java.util package.

  nextGaussian()方法在java.util包中可用。

• nextGaussian() method is used to generate the next pseudo-random Gaussian double value with mean 0.0 and standard deviation 1.0 from this Random Value Generator.

  nextGaussian()方法用于從該隨機值生成器生成平均值為0.0，標準差為1.0的下一個偽隨機高斯雙精度值。

• nextGaussian() 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.

  nextGaussian()方法是一種非靜態(tài)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。

• nextGaussian() method does not throw an exception at the time of returning double.

  返回double時， nextGaussian()方法不會引發(fā)異常。

Syntax:

句法：

public double nextGaussian();

Parameter(s):

參數(shù)：

• It does not accept any parameter.

  它不接受任何參數(shù)。

Return value:

返回值：

The return type of the method is double, it returns next pseudo-random Guassian distributed double value with mean and standard deviation from this Random Generator.

該方法的返回類型為double ，它從該隨機數(shù)發(fā)生器返回下一個具有均值和標準差的偽隨機Guassian分布double值。

Example:

例：

// Java program to demonstrate the example // of double nextGaussian() method of // Randomimport java.util.*;public class NextGuassianOfRandom {public static void main(String args[]) {// Instantiates Random objectRandom ran = new Random();// By using nextGuassian() method is// to return double guassian pseudo-random// value with mean 0.0 and SD 1.0 by// using Random Value Generatordouble val = ran.nextGaussian();// Display valSystem.out.println("ran.nextGaussian(): " + val);} }
