• 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()方法用于返回以位為單位的偽隨機數。

• 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()方法是一個非靜態方法，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。

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

  在返回隨機位時， next()方法不會引發異常。

Syntax:

句法：

protected int next(int ran_bit);

Parameter(s):

參數：

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

  int ran_bit –表示隨機位(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.

方法的返回類型為int ，它從此Random生成器返回偽隨機數。

Example:

例：

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

Output

輸出量
