How to add a layer to a map from a layer file

Summary
This article illustrates how to open a layer file and add the layer to a map in the code.

Adding a layer to a map from a layer file
This operation is performed using the MapDocument class, which can open layer files, as well as map documents (.mxds) and published map files (.pmfs). See the following code:
[Java] 
static void addLayerFileToMap(IMap map, String path)throws Exception{
    IMapDocument document = new MapDocument();
    //Use the map document class to open the layer.
    document.open(path, "");
    //When opening a layer with the map document class,
    //the layer is added to a new document as the first
    //layer in the first map.
    map.addLayer(document.getMap(0).getLayer(0));
}
