When there are multiple continuation lines, indentation may be varied beyond +4 as desired. When line-wrapping, each line after the first (each continuation line) is indented at least +4 from the original line. The Google Style Guide states the following: 4.5.2 Indent continuation lines at least +4 spaces This shortcut comes in handy if we want to override toString() method that returns information of relevant fields of the class.The current standards do not stipulate exactly how a line that needs to be split should be indented. Alt + Shift + S, S: Generates toString() method.We got the following result (example): int hashCode() else if (!username.equals(ername)) This shortcut brings the Generate hashCode() and equals() dialog as below: Select the fields to be used in hashCode() and equals() method, and then click OK. Alt + Shift + S, H: Generates hashCode() and equals() methods, typically for a JavaBean/POJO class.This shortcut brings the Generate Constructors from Superclass dialog which allows us to choose the constructors to be implemented in the subclass: In this case, we need to write some constructors similar to the Exception superclass. A common example for using this shortcut is when creating a custom exception class. Alt + Shift + S, C: Generates Constructors from Superclass.This shortcut is very useful when you want to generate code for a constructor that takes class’ fields as its parameters. Alt + Shift + S, O: Generates constructor using fields.This is a very handy shortcut that helps us generate getter and setter methods quickly. Alt + Shift + S, R: Generates getters and setters for fields of a class.Alt + Shift + S: Shows context menu that lists possible actions for editing code:įrom this context menu, you can press another letter (according to the underscore letters in the names) to access the desired functions.Ctrl + Shift + \: Removes block comment.Ctrl + Shift + /: Adds block comment to a selection.This shortcut adds single-line comment to current line or a block of code. Ctrl + /or Ctrl + 7: Toggle single line comment.This is useful as it helps you avoid manually using Tab key to correct the indentation: Ctrl + I: Corrects indentation for current line or a selected code block. Note that, if nothing is selected in the editor, Eclipse applies formatting for the whole file: This shortcut is very useful when you want to format messy code to Java-standard code.
