Disable warning in IntelliJ for one line
Mostly in IntelliJ, you can click on the line and Alt+Enter, and it will have options for suppressing the warning, among other things.
Expanding upon Ryan Stewart's answer, in IntelliJ, use Alt+Enter, then select the first sub-menu, then the last item: Suppress for statement.
Update
Using IntelliJ IDEA 13, I noticed an additional menu item: "Suppress for statement with comment". This will use the IntelliJ style //noinspection unchecked. If you select "Suppress for statement", IntelliJ will insert this text: @SuppressWarnings("unchecked").
Depending on the warning you can use @SuppressWarnings. Eg:
@SuppressWarnings("deprecation")yourLineWhichIsDeprecated;Take a look at this answer for a pretty long list of warnings you can suppress. Check the other posts on that topic for more details.
