How can I refactor this function? I show a list of plugins in JSF, and I should filter them. I added function filterPlugins but I have some questions:Should we simplify block with conditional expression?I reassign global variable plugins to introduce my filter function (is it not bad practice?)load()@NotNull@DataModel(plugins)List<Plugin> plugins;public void load() {    plugins = pluginManager.getPlugins();    plugins = filterPlugins(searchParam);    SortingUtil.sort(plugins, SortingUtil.SortType.ID_ASC);    if (plugins.size() > 0) {        if (plugin != null && plugins.contains(plugin)) {            selectPlugin(plugin);        } else {            selectPlugin(plugins.get(0));        }    } else {        plugin = null;    }}@SuppressWarnings(unchecked)private List<Plugin> filterPlugins(final String searchParam ){      return (List)Iterables.filter(plugins, new Predicate<Plugin>() {        @Override        public boolean apply(@Nullable Plugin plugin) {            return  plugin.getName().contains(searchParam)                    || plugin.getNetworkClasses().contains(searchParam)                    || plugin.getClassName().contains(searchParam);        }    });}@Overridepublic void selectPlugin(Plugin p) {    plugin = p;        }Plugin.javapublic class Plugin {    private static final long serialVersionUID = -8424575107726996696L;    @NotNull    private Long id;    @NotNull    private String name;    @NotNull    private String networkClasses;    + setters and getters}I want to pay your attention this code interacts with JSF page:<a:support event=onRowClick action=#{configPlugins.selectPlugin(p)} reRender=pluginList/><a:commandLink action=#{configPlugins.removePlugin(true)} reRender=pluginList/>
