要在Java中生成特定范围内的随机整数,您可以使用`java.util.Random`类。以下是一个示例,展示了如何在Java中生成一个介于最小值(min)和最大值(max)之间的随机整数: ```...
This Random().nextInt(int bound) generates a random integer from 0 (inclusive) to bound (exclusive). 1.1 Code snippet. For getRandomNumberInRange(5, 10), this will generates a random integer between 5 (inclusive) and 10 (inclusive). private static int getRandomNumberInRange(int min, int...
