Refactor to move a class to its own file

Just use the Move Refactor (F6 or Refactor > Move from the menu) with your cursor on the second class name. After promoting it, you will likely want to make the class public.

Is it possible that this suggests a new file with the same name as the class I want to move?

When I "Move..." the "TO:" field holds the old file name, so I always have to write the new name by hand.

Hello Sebastian,

Please try "Refactor | Move Inner Class to Upper Level"

Sorry just saw this is ItelliJ Forum. I use Webstorm. The option seems to be missing there? 

@Sebastian What language do you use? Please provide more details on your case.

Oksana Chumak I use Typescript.

I wish I could go from:

class Foo {
  do() {
    bar.do2(); 
  }
}


// to this


class Foo {
  constructor(public bar:any){}
  do() {
    this.bar.do2() 
  }
}

@Sebastian Obentheuer As we discussed in https://intellij-support.jetbrains.com/hc/en-us/community/posts/360009307519-How-can-I-refactor-a-field-into-the-constructor-, there is no such Typescript refactoring; if you miss it, please feel free to file a feature request to https://youtrack.jetbrains.com/issues/WEB
