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:

I'm using Intellij IDEA 13 for android development.
Some methods has long list of parameters. For example, db.query(...) and I can't remember the order of them.
Is there any plugin or can i change some settings to make IDEA insert variables from function template?
Thanks
You have a couple of options. Ctrl+P will show a lit of the parameters, with the current one bolded. As long as you have either the source or javadoc for the library (or JDK/SDK) attached to the corresponding definition, you will see the parameters' names.
If you invoke code completion while entering parameters, IDEA will show at the top only ones that are of the correct type. Furthermore, if one of you local variables is the same name (or similar to) the required parameter's name, it will be at the top of the list. So if there is a method that takes an int named 'width', and I have several int variables, but one is named 'theWidth', it would be at the top. (Again, this assumes you have javadoc or source attached so IDEA can determine parameter names.) If IDEA can find local variables that satisfy all parameters (or all the first x parameters) of the method, there will be an option in the code completion list to complete all of them, The icon will be a double circle. The below screen shot shows how the HttpServletReqest is at the top of the list. So I do not have to remember if the parameter order is "request, response" or "response, "request". Notice the fourth option is to complete both the request and the response.
In my eclipse, when i check for method help with ctrl+space i see the method parameters are showing like strings, int as arguments. Not showing like, string name/int id .
getAttribute(String arg0)
How can i make the eclipse to show the method as getAttribute(String name)
This is really difficult to me identify which param i should pass fro a method.
Any idea, where should i set the settings?
This problem happens when eclipse can't find the source or attached Javadoc, since java argument names are usually not present in the .class files (it would only be present in debug, and not for the interfaces).
You can check if a source or a documentation is attached using the helper F3.
You can increase the timeout eclipse uses for fetching a parameter name from attached Javadoc in the settings.
You can also attach the corresponding documentation jar or source jar as a dependency in order to allow eclipse to look-up the corresponding source.
I have just started using eclipse Indigo for Scala development. Is there a setting anywhere in eclipse to change the filter behavior to "anywhere" when I type X. and invoke completion?
If I have an object foo with a field foo.name and methods foo.fullName, foo.capAllNames I would like all three to remain in the selection list when I type foo.name.
Currently the list is filtering on the start of the word so only the foo.name property would remain in the example given. I would like the filter to be based on the text being present anywhere in the word, can this be done in eclipse?
Thanks

Looks like Code Recommenders as suggested by moeTi will do the job but I might have to wait for a while until the latest bug fixes filter through to a release that will play nicely with the Scala plug in (it/eclipse threw exceptions when I installed it):

While typing in Eclipse (Java) I often have the problem that when I begin to type accessors, the caret jumps down to the beginning of the constructor definition. So in a document like this:
private int mSomeInt;
public
in|public MyClass(){
}
I would like to manually type out the accessor (getter/setter) for mSomeInt, but when I press space after 'public' above, the caret jumps to the beginning of 'public MyClass'.
I often type complete lines to look up and find my methods jumbled with the constructor (like above).
Any help would be appreciated.
Note - this isn't only with accessors but rather any access modifiers that I define before the constructor or another method.
Edit
After unsuccessfully trying Deco's solution below, I've managed to narrow it down a little further.
The problem only happens if I have all the blocks in the file in a collapsed state (ctrl+shift+numPadDivide). I can see the problem is now that the new access modifier I type is then (quickly) collapsed into the below method. i.e. Eclipse is actually taking the first accessor modifier and collapsing everything from there, even though my intention is actually to write a new method.
The only solution I've been able to find is to only edit the source with all the 'fold' elements unfolded.
Under Window -> Preferences -> <Language> (e.g. Java) -> Editor there is a Content Assist menu item where you can configure auto completion and caret placement as well as auto-activation of it and the delay it uses.
Edit:
After your update to the original question I was able to successfully replicate this in Eclipse Indigo. When you have all of the code blocks collapsed it looks like Eclipse assumes that the code you are writing needs to be in that block (rather than as a variable declaration). I'm not sure if this is expected behaviour or not - but the only way around it I've found is to edit the code with the main block open, and then close it after the fact - or turn folding off altogether.
From what I can tell there are various folding plugins/addons that you can get for Eclipse which override the default behaviour and might function better? A quick Google search will be able to get you a list of them quickly.
I'd probably also suggest posting this as an issue on the Eclipse support site for their official answer.
Unfortunately this issue still exists for me in the latest Elcipse version (Kepler).
As the issue only occurs when the document is 'folded', the work around this is to either disable folding in the editor - or disable folding on 'Members' from the :
Preferences -> Java -> Editor -> Folding
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 ;-)
