本资料包系统性地探讨了Java编程语言中程序流程控制的核心机制,重点解析了条件判断语句(if-else、switch)和循环结构(while、do-while、for)的语法、特性及应用。通过对不同控制结构在解决实际问题(如实现猜数字游戏、打印九九乘法表、数据...
1. java.util.Random 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). ...
The program uses a random number generator to simulate our case. Random r = new Random(); boolean male = r.nextBoolean(); TheRandomclass is used to produce random numbers. ThenextBooleanmethod returns randomly a boolean value. if (male == true) { ...
