idea中检索此方法中有哪些参数以便我们使用——1.类图。2.双击shift

遇到问题
在我们长时间不使用某个方法的时候,会忘记这个方法中应该填哪些参数,是填一个还是两个?又或者填int还是String?
那么我们这个时候就要检索此方法的所有可填参数,来辨别我需要使用哪个方法以及哪些参数
尝试解决
- 使用类图模式观察,我们需要知道此方法属于哪个类,比如substring方法属于String类
我们右键点击Diagrams——Show Diagrams

点击methods就可以看到String类的所有方法
- 双击shift方法检索,也可以检索到,不过感觉没有类图检索的专业详细

解决方法
- 类图模式,不但可以查看所有方法,还可以查看类中构造器,不过需要知道检索方法属于哪个类
- 双击shift,不但可以检索jdk系统方法,也可以检索用户方法
双击shift检索系统方法

我们还可以点击进去查看方法源码,分析此方法的作用
