一、打开idea发现用了setters和getters注解的代码还是报红色、然后是因为idea里面没有下载lombok的插件 二、Idea安装Lombok插件:点击File->Settings->plugin->直接搜素lombok插件->点击安装->重启Idea->安装完成 三、操作完成之后就发现不报错了!!

首先让我们来规定一下getters和setters的特性: Getter Getter方法的名字以get开头,没有方法参数,返回一个值。 Setter Setter方法的名字以set开头,有一个方法参数。 setters方法有可能会有返回值也有可能没有,一些Setter方法返回void,一些用来设置值,有一些对象的setter方法在方法链中被调用(译者注:这类的setter方法必...

首先让我们建立一个 getters and setters的规则: get getter方法的名字以“get”开始,取0个参数,并返回一个值。 set setter方法的名字以“set”开始,并且取1个参数。 安装者可能会也可能不会返回一个值。 一些setter返回void,一些set的值,另外一些setter被调用的对象用于方法链接。 因此你不应该假设一个setter的...
Properties – Java only has fields and methods. “Properties” are implemented as get* and set* methods. I really miss properties, especially after typing 10 getters and setters in a row. var keyword – Another small but very nice feature in C# that helps make code more compact and reduce...
