Is there any quick way to add a parameter in all methods of a package in eclipse?
If you mean to add a few parameters for one method and after that it'll be updated automatically in all packages , there is. Right click on the method and there is option Refactor -> Change Method signature, here you can add/remove parameters.
See http://www.raymondcamden.com/index.cfm/2009/3/16/Multifile-search-and-replace-in-Eclipse. You will have to modify the instructions there just a tad for your needs:
Instead of telling Eclipse to search for a literal string you will be searching for a regular expression pattern that describes a method call/definition. I'll leave that as an exercise for you ;-)

Currently I get this result with Eclipse auto completion.
System.console().printf(format, args)
Of course, Eclipse shows the parameter types as popup, but I want the types to be displayed in front of parameter names too. Like this.
System.console().printf(String format, Object ... args) // `String`, `Object` inserted automatically.
Can I configure Eclipse to show the parameter types too?
Of course not. Eclipse auto completion only suggests valid syntax, while your demand is not valid java code.
An alternative for you might be to open the "Declaration" view or the "JavaDoc" view. Both will always show the declaration/JavaDoc of the currently selected element while you are typing. Therefore you could see the method declaration/javadoc when writing that method call.
Update
Whoever came across this old question. You can use eclipse code mining now:
parameter name hint for Eclipse
Lets say for example I write many times priavte instead private.
Is there a way to let Eclipse automatically fix my common typo?
Something like construct a map of my common typo to its desire fix,
and then just let Eclipse fix it without asking me about that.
Are there any other IDE\editors that have such support?
There is no builtin support for automatically changing strings. The closest to your request are the templates of the Java editor, but even those must explicitly be activated using CtrlSpace.
To get around your problem, I suggest simply not to write that much yourself. If you want to declare a private field, type just "pr" and hit CtrlSpace to invoke code completion. Eclipse can do code completion quite well, often even without any trigger characters (try it with an empty class file).
I'm looking for a way to refactor all usages of a method with another. I'm de-singleton-izing a class, and I'm trying to replace all of the getInstance() methods with another method.
In my case, I'd like to change all usages of OldClass.getInstance() to be NewClass.getInstance().getOldClass(0). Is this possible with NetBeans' refactoring tools?
In Netbeans you can refractor the name of the method, but you can't change C.m() to C.m().m2() with refractoring tools.
So the best solutions is to go with Edit->Replace or Replace in project.
Then replace all .getInstance() by .getInstance().getOldClass(0). (Take care of the scope). Don't worry it doesn't replace all occurence directly, it finds match then it displays a tree with checkboxes, you can click on Replace to replace the selected occurence.
Im currently doing a lot of testing with JPA entities, where i have to keep calling the setter methods on the entity that looks something like this :
myEntity.setXXX(value);
myEntity.setYYY(value);
myEntity.setZZZ(value);
Is there any magic shortcut or menu in eclipse IDE to generate all the setter-method-calls that starts with "set", like those displayed in the ctrl-space (auto completion) popup (i think the inherited methods from Object are not being shown at popup) ?
So im imagining something like :
i type myEntity.set
and myEntity.set* are generated right away
Im a lazy programmer and currently using Eclipse Helios IDE.
Thank you !
Edit
Im not looking for source -> generate getter and setter, because that would helps me in generating the methods itself. Generating the method calls is what i want to achieve.
I have found the answer (I was always searching for this thing)...
The easiest way is to expand the class members in the "Package Explorer", sort them by name, multi-select all the setters, and then you have in the clipboard all the method names...
;-)
I like #Oscar's answer. It does lead to some cleanup though.
When I paste from the clipboard, I get something that looks like this:
setOne(int)
setTwo(String)
In order to clean this up, I first add semicolons with this search/replace regexp:
search = (.)$
replace = \1;
Then I add the getter calls (assuming incoming data object is named "data"):
search = s(et.*)\(.*
replace = s\1(data.g\1());
This doesn't handle multiple arguments in a method call...
you can use the outline at right side. There you can sort alphabetically or by declaration order using the toolbar button of the view.
and then you can filter out non required this.
From here also you can copy..all setter functions or getters functions names...
There is eclipse plugin to do that. The name of the plugin is **
FastCode
**. There are so many templates. Among those there is template to generate code for create object of the class and all setters method.
Source --> Generate Getters and Setters...
You can also get at it via the Quick Fix command (Ctrl+1) when the cursor is on a property.
EDIT
If you are simply looking for a faster way to copy properties from one object to another I suggest that you look at using reflection. I think this path would be much easier long term then generating the same-looking code over-and-over.
Commons BeanUtils can take away some of the pain in writing pure reflection code. For example, copyProperties takes a destination bean and either another bean or a Map as the source.
I have a method which I want to delete. This method is being called from n number of classes. I want to delete this method using refactoring and also make eclipse delete all calls to this method rather than go and clean up in each file. I could not find a straight way to do this from refactor (I am using ganymede)
Delete the method body
Then select the method
Refactor -> Inline
I don't think it can be done through refactoring. You can do a Search and replace using regex though.
