随机类的next()方法 (Random Class next() method)

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

  next()方法在java.util包中可用。

• next() method is used to return the pseudo-random number in bits.

  next()方法用于返回以位为单位的伪随机数。

• next() 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.

  next()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。

• next() method does not throw an exception at the time of returning random bits.

  在返回随机位时， next()方法不会引发异常。

Syntax:

句法：

    protected int next(int ran_bit);

Parameter(s):

参数：

• int ran_bit – represents the random bits (ran_bit).

  int ran_bit –表示随机位(ran_bit)。

Return value:

返回值：

The return type of the method is int, it returns the pseudo-random number from this Random generator.

方法的返回类型为int ，它从此Random生成器返回伪随机数。

Example:

例：

// Java program to demonstrate the example 
// of int next(int ran_bit) method of 
// Random
import java.util.*;
public class NextOfRandom {
public static void main(String args[]) {
// Instantiates Random object
Random ran = new Random();
// By using next() method is
// to return the next to next
// pseudo-random number
int val = ran.nextInt();
// Display val
System.out.println("ran.nextInt(): " + val);
}
}
