Generally, this dialog is used to extract new variables. Depending on the language, there may be additional options.

* In Java, you can declare the new variable `final`. To make this dialog accessible for Java, you have to disable [in-place refactoring in the editor settings](code-editing.html#in_place_refactorings).

* In JavaScript, you can select to extract a (global) variable or a constant. For JavaScript 1.7, JavaScript 1.8.5, ES5, and ES6, there is also an option of extracting a local variable.

| Item | Description | Language |
| --- | --- | --- |
| Variable of type | The type of the new variable. | Java |
| Name | Specify the name for the new variable. | All |
| Replace all occurrences | Select this option to replace all the occurrences of the selected expression (if more than one occurrence of the selected expression is found).  | All |
| Declare final | Select this option to declare the new variable `final`. | Java |
| Declare var type | Select this option to declare the introduced variable with `var` instead of an explicit type, when local variable type inference is available. | Java |
