IDEA has a universal shortcut key (Alt Enter), which is very powerful. The same shortcut key can prompt you to do different operations according to different contexts. Many people may not know these functions, but also handle them manually when dealing with codes.

Alt Enter can do a lot of things for you, but I’ve come up with about 17 things:

  • Converting lambda expressions
  • Equals the flip
  • Automatic guide package
  • Exception handling
  • SimpleDateFormat is converted to ThreadLocal encapsulated SimpleDateFormat
  • Annotation mobile
  • Easy JSON string handling
  • Convert to efficient binary
  • The if… Else becomes simple ternary operation and some simplified operations
  • Introducing local variables
  • Implementing an interface
  • Implementing abstract classes
  • Fix method return value, add input parameter, decrease input parameter, method generation, etc
  • String related operations
  • , + < and so on
  • Java access modifier change operations
  • Automatically generate property actions

In order to give you a more intuitive view of the effect, I recorded a GIF demo.
