在这个示例中,我们首先导入了java.util.Random类。然后,在main方法中,我们定义了一个最小值(min)和一个最大值(max)。我们调用了getRandomNumberInRange方法,该方法返回一个介于最小值和最大值之间的随机整数。最后,我们打印出生成的随机数。 getRandomNumberInRange方法接受两个参数:最小值和最大值。首先,我们...
intrandomNumberInRange=random.nextInt(100)+1; 1. 上述代码中,random.nextInt(100)生成一个范围在0到99的随机整数,然后将其加1,得到范围在1到100的随机整数。 4. 代码示例 下面是一个完整的示例代码,演示如何在Java中实现随机数范围: importjava.util.Random;publicclassRandomNumberGenerator{publicstaticvoidma...
