Lets look at each one of them with examples:<\/p>\n
Rename<\/h4>\n
Rename lets you change the name of a variable or an object or a class anywhere in your code. You select the text in your editor and choose the Rename menu option. It will ask you enter the new name for the object:<\/p>\n
<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n Then it will show a preview of the changes that will be effected:<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n Clicking on Apply will make the changes permanent.<\/p>\n <\/p>\n Extract Method is used for taking some code out of an existing function or method and converting it into a separate method. This is probably the most common and useful cases of refactoring, where you find that a certain piece of code has been repeated or needs to be callable from a lot of places.<\/p>\n In the sample below, we select some code to refactor:<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n and we choose a new method into which the code will go into. You can enter the name of the method to what you want . Notice that the original selected code gets replaced by the new method call.<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n If you have a class level attribute and want to convert into a field with get\/set methods, then this method is useful as it saves you a lot of typing.<\/p>\n Select the variable . It will automatically prefix a capital M to the name. You can change that if you wish.<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n After execution, the original variable declaration remains and a new get\/set method pair is added.<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n If you want to create an interface for any public method in a class, then this option makes it easy . Choosing this option from the Edit menu will show you the public methods in the current class in your editor:<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n You can then choose the name of the Interface and which method(s) you want to declare an interface for. A new file will be created with the interface declaration:<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n As the name suggests this is used to remove some parameters from a function or method call. Be warned that it will\u00a0 do a syntactical change only all across the source code.<\/strong> Your code may stop working or have unexpected results if the logic changes due to this operation. Select the function you want to remove parameter(s) for:<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n It will show you a preview of the changes that will be done. Click Apply to make changes permanent.<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n Reordering parameters is used for changing the sequence of the arguments being called in a function. Select the function you want to change it for. Then use the arrow keys to change the order of the parameters.<\/p>\n<\/a><\/p>\n<\/a><\/p>\nExtract Method<\/h4>\n
