Eclipse remove a static import

Question

With eclipse i can easily transform the static invocation to

import java.util.Arrays;
import java.util.List;

public class StaticImport {
    public static void main(String[] args) {
        List<String> list = Arrays.asList("hello", "world");
        System.out.println(list);
    }
}

to a static import:

import static java.util.Arrays.asList;

import java.util.List;

public class StaticImport {
    public static void main(String[] args) {
        List<String> list = asList("hello", "world");
        System.out.println(list);
    }
}

I put the cursor on the method name (asList) and press Ctrl-Shift-M (Add Import).

Now, for some refactoring reasons, i want to remove the static import and get back to the first code:

List<String> list = Arrays.asList("hello", "world");

Is there a shorcut quickly do that ?

Answer 1

You can't remove an (static) import statement with a shortcut, unless it's unused.

So, first comment out the statement:

//List<String> list = asList("hello", "world");

Then, activate the shortcut for Organizing Import Statements (Ctrl + Shift + O) and the unused import statements will be automatically removed.

Finally, uncomment the line you commented first and refactor it so it compiles:

List<String> list = Arrays.asList("hello", "world");

Thanks, this is the trick i use to do. Note that you have to import java.util.Arrays again at the end. – Canzonet

Even if it's a former question:

You can do that using Eclipse Cleanup or Eclipse Save Action.

Warning: It looks like a bug to me but unchecking the options doesn't perform the opposite action.

Cleanup:

• Go to Preferences > Java > Code Style > Cleanup
• Click on Edit
• Go to member accesses tab
• In Static accesses section, check Qualify field accesses, qualify methode accesses
• Right Click on the file > Source > Cleanup

Puntual cleanup:

• Right click on the file > Source > CLeanup
• Use custom profile
• Go to member accesses tab
• In Static accesses section, check Qualify field accesses, qualify methode accesses
• Right Click on the file > Source > Cleanup
• Apply > OK

Save action:

• Go to Preferences > Java > Editor > Save action
• Check "Additional actions"
• Go to member accesses tab
• In Static accesses section, check Qualify field accesses, qualify methode accesses
• Just save the file
