nextfloat

随机类nextFloat()方法 (Random Class nextFloat() method)

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

  nextFloat()方法在java.util包中可用。

• nextFloat() method is used to generate the next pseudo-random float value between the range 0.0 and 1.0 from this Random Value Generator.

  nextFloat()方法用于从该随机值生成器生成介于0.0和1.0之间的下一个伪随机浮点值。

• nextFloat() 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.

  nextFloat()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。

• nextFloat() method does not throw an exception at the time of returning float.

  返回float时， nextFloat()方法不会引发异常。

Syntax:

句法：

    public float nextFloat();

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 float, it returns next pseudo-random distributed float value between the given range from this Random Generator.

方法的返回类型为float ，它从该Random Generator返回给定范围之间的下一个伪随机分布float值。

Example:

例：

// Java program to demonstrate the example
// of float nextFloat() method of
// Random
import java.util.*;
public class NextFloatOfRandom {public static void main(String args[]) {// Instantiates Random object
Random ran = new Random();
// By using nextFloat() method is
// to return float pseudo-random
// value between 0.0 and 1.0 by
// using Random Value Generator
float val = ran.nextFloat();
// Display
System.out.println("ran.nextFloat(): " + val);
}
}
