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...
✏️ As you have seen, you can often provide aninitial valuefor a field in its declaration. 📜 正如上面你所看到的,你可以在属性声明的时候就给它提供一个初始值(Initial Value) ✏️ This works well when theinitialization valueis available and the initialization can be put on one line. ...
