Disable “not used” warning for public methods of a class

The new intellij upgrade (10.5) now shows a warning that some of the methods defined for a class are not being used. These methods are public and I plan on not using all of them as I have created them to support the API expected. I would like to disable this warning (not used for public methods in a class). Is there a way to do it?.

You can disable it for a single method like this

@SuppressWarnings("unused")
public void myMethod(){...}

IDEA 2016.3

In the upcoming version IDEA 2016.3 (preview version already available) it is now possible to adjust the inspection scope:

< IDEA 14.0

If you want to highlight unused public methods, please enable the "Settings|Inspections|Declaration redundancy|Unused declaration" global inspection.

If you want to highlight unused private methods, please enable the "Settings|Inspections|Declaration redundancy|Unused symbol" local inspection.

So, if you want to highlight unused private members, but do not highlight unused public members, turn off "Unused declaration" and turn on "Unused symbol".

I've just tested it using IDEA 13.1.4, and it worked exactly as described.

IDEA 14.x

In IntelliJ IDEA 14.0.x the settings are under:

Settings | Editor | Inspections | Declaration redundancy | Unused symbol/declaration

In IntelliJ IDEA 14.1 the option appears to be gone..

Disable Settings | Inspections | Declaration redundancy | Unused Declaration code inspection. As an option you can create a custom scope for your API classes and disable this inspection only per API scope so that it still works in the rest parts of your project.

In the latest version, this options is under Settings>Inspections>Java>Declaration redundancy>Unused declaration>Methods uncheck options which are not required.

I think the best way to avoid the highlighting of that unused public methods is writing a couple of test for those methods in your API.

Here is the 2019 update for: IntelliJ IDEA 2018.3.2 (Community Edition) Build #IC-183.4886.37, built on December 17, 2018

Settings | Editor | Inspections | Declaration redundancy | Unused declaration

This is an old thread, but I ended up here faster than I could find a solution so I'm going to go ahead and share my findings. First, I am not sure if we are working with the same language (JS here,) but fiddling with the GUI-based tools, here is what I ended up with. The following code was giving me the infamous "not used" warning:

/**
 * @class sample class
 */
var MyClass = function () {
    return this;
};

/**
 * Some public method
 * @api public
 */
MyClass.prototype.myMethod = function () {
    return null;
};

There goes the "Unused definition myMethod" The inspector ended up suggesting to ignore this specific issue by adding

//noinspection JSUnusedGlobalSymbols

right on top of this specific method so that the following code no longer results in this warning:

//noinspection JSUnusedGlobalSymbols
/**
 * Some public method
 * @api public
 */
MyClass.prototype.myMethod = function () {
   return null;
};

Other warnings (typoes etc..) still seem to show up, including unused local variables and parameters, so it seems to isolate this particular issue. The downside is that it tends to pollute your code if you have lots of it...

I just clicked "suppress for statement" and webstorm prepended this:

//noinspection JSUnusedGlobalSymbols
