something like this?
try {
BufferedImage[] icons = new BufferedImage[] {
ImageIO.read( Main.class.getResource( "/Interface/icons/animalia-128.png" ) ),
ImageIO.read( Main.class.getResource( "/Interface/icons/animalia-64.png" ) ),
ImageIO.read( Main.class.getResource( "/Interface/icons/animalia-32.png" ) ),
ImageIO.read( Main.class.getResource( "/Interface/icons/animalia-16.png" ) )
};
appSettings.setIcons(icons);
} catch( IOException e ) {
// log.warn( "Error loading icons", e );
}
