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 // Randomimport 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); }}
