Combining multiple @SuppressWarnings annotations - Eclipse Indigo

Question

So the issue is being able to combine multple warning suppressions so that each item doesn\'t need it\'s own @SuppressWarnings annotation.

So for example:

Answer 1

If you take a look inside the annotation you will see this:

public @interface SuppressWarnings {
    String[] value();
}

as you see, the value parameter is an array of Strings... so the parameter in the annotation can be: value1, value2 or value3 where

final String[] value1 = { "a1" };
final String[] value2 = { "a1", "a2" };
final String[] value3 = { "a1", "a2", "a3" };

i.e.:

@SuppressWarnings({"unused"})
@SuppressWarnings({"unused", "javadoc"})

you can oft see something like

@SuppressWarnings("unused") 

and this is a particular case allowing one element wit no "{ }"

Answer 2

Use the following: @SuppressWarnings({"unused", "unchecked"})
