nextgaussian

随机类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()方法用于从该随机值生成器生成平均值为0.0，标准差为1.0的下一个伪随机高斯双精度值。

• 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()方法是一种非静态方法，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。

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

  返回double时， nextGaussian()方法不会引发异常。

Syntax:

句法：

public double nextGaussian();

Parameter(s):

参数：

• It does not accept any parameter.

  它不接受任何参数。

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.

该方法的返回类型为double ，它从该随机数发生器返回下一个具有均值和标准差的伪随机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 object  Random 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 Generator  double val = ran.nextGaussian();  // Display val  System.out.println("ran.nextGaussian(): " + val); }}
