I want to use something like `Setting.RES_WIDTH` in my code without the need for a getter function (ie: custom getter, enum's `.name()`, `.toString()` or `.valueOf()`).

Someone suggested using a final class, so I wrote this.

    public final class Setting {
    
    	public final static String RES_WIDTH 		= "resolution_width";
    	public final static String RES_HEIGHT 		= "resolution_height";
    	public final static String FULLSCREEN 		= "fullscreen_enabled";
    	public final static String VSYNC 			= "vsync_enabled";
    	
    	//Prevent someone from creating an instance of this class
    	private Setting() {}
    }

This code works, but I am wondering if there are any kind of issues (performance, GC, etc) that might arise from using this.
