Eclipse Help
MUST READ !!!
Examples of Tips &Tricks
Eclipse Built-in Tutorials
Eclipse Navigation Tips
Navigation Shortcuts ●
Search : Ctrl + T (T = Types: class, interface, enum...) cf also Ctrl + R (R = Resources: files, folder..)
Camel Case Names ●
“Camel Case” : Split Words + UpperCase first letter of words
●
English => read Right to Left for class behavior
●
example: “ObjectInputStream” ●
= A Stream
●
More precisely... an Input stream
●
More.. an Object input
●
Other examples: NPE = NullPointerException, OOME
●
MUST known for JDK !!
Ctrl+T (Search) + Camel Case ●
To search for ObjectInputStream
●
You can use ●
OIS
●
O*I*S*
●
Obj*Inp*Stream
●
ObjectInputStream
●
java.io.ObjectInputStream
Search Within a File ●
●
●
“Ctrl + F” (then next Ctrl+K) => search text exact case-sensitive case-insensitive Regular expression “Ctrl + O” Search member => methods, fields “Ctrl + L” Goto Line
Other Useful Navigate Keys ●
Shift+Ctrl+P = Go to matching bracket
●
Ctrl+. = Go to next error
●
Shift+Ctrl+UP/DOWN = next member
●
Alt+LEFT (back) / Alt+RIGHT (forward)
Ctrl+O ●
Search members... ●
Filter by prefix only in declared class
●
●
Filter by regexp Show ALL (inherited) Ctrl+O
Search in Multiple Files ●
Ctrl +H idem Ctrl+F, but in all files
●
Can search by Text, by Java, by Task...
●
Can search by Working Set
Customize ...
Working Set
Search By Regular Expression ●
Very powerfull in eclipse …
●
Standards: (), *, ?, \( \) *, [^], .
●
Non-standards:
●
●
\s = any space
●
\w = any letter/digit from a word
●
(s?) = multi-line regexps
Replace ●
( .. ) = capture block \(, \) for parenthesis
●
=> $1, $2, … captured blocks
Open Call Hierarchy Ctrl + Alt + H
Type Hierarchy Ctrl+T , F4 ●
Ctrl+T On a Type => show all its sub-types In a View: F4
In a Floating Tip View: CTRL+T
Ctrl+T on Method => search impl in sub-class ●
Design Pattern => Use interfaces not classes... Pb: difficult to navigate Solution: Ctrl+T
Method Override / Implement ●
Upward Triangle = see Up in parent class
Full Triangle : override (super = concrete)
Empty Triangle : implements (super = abstract)
Resource Explorer / Filter ●
Use Java View for Java / Resource View for …
●
See Also Perspective
Filter: Hide NOTHING = show all ...
Extensions to Show: Nothing BUT Resources
Eclipse Editor Tips
Shift + Ctrl + O = Organize Import ● ●
NEVER do manually !! Customize Order, Type Filter: Window>Preferences>Java
Ctrl + 1 … QuickFix ●
●
Example: ●
Method does not exists => Create it
●
Method not public => change visibility
Ctrl+1 = Right Click on fault = Click on Pb
Ctrl + SPACE ●
=> AUTOCOMPLETION
●
Code Template, Example: sysout + Ctrl+SPACE => System.out.println() main + Ctrl+SPACE => public static void main(... for =>
User-Defined Code Template ●
Frequent use : Logger (SLF4J), Separator, constructor, serialId, ...
Auto Import Generate Code Replace var by contextual value
Customize Code Template Window > Preferences > Java > Editor > Templates
Source Menu – Shift+Alt+S ●
Classical needs : getter/setter equals(), hashCode(), toString()...
Getter / Setter Code Generator Shift+Alt+S (Source) > R (getter) > Alt+A (all) > ENTER (OK)
Equals/HashCode Code Generator Shift+Alt+S (Source) > H (hashcode) > ENTER (OK)
More Code Generator... ●
Example : Delegates
Eclipse Refactoring Tips
Rename ●
For a File : F2 (standard shortcut)
●
For all others : Shift+Alt+R
●
In place edition... (class, local var, ...)
Refactoring Menu: Shift+Alt+T
Extract Method : Shift+Alt+M Select fragment (including ending “;” Shift+Alt+M (method)
d e t c e t De
lls a 2c
Extract Local Var : Shift+Alt+L Select expr (not stmt: no ending “;”) Shift+Alt+L (local)

Eclipse Debugging Tips
F11 = Start / Debug / Relaunch ●
●
Note: use the Debug Perspective to Debug
Press F11 on method with @Test => start JUnit
●
Press F11 on main() => start
●
Press F11 on existing launch => re-start
F5 < F6 < F7 < F8 ●
Take your four fingers on keys F5 .. F8
●
F5 = step into
●
F6 = step over
●
F7= step out
●
F8 = resume
