if/else vs. switch

When writing code that branches on enum values, instead of if/else blocks, use the switch statement like so:

    switch (selectedTab) {
    case (Tab.SITES):
        //do something for sites
    case (Tab.CATEGORY):
        //do something for category
    case (Tab.DEMOGRAPHIC):
        //do something for demographics    
    case (Tab.ALL_SITES):
        //do something for all sites
    }

Lengthy and nested methods: Methods should small, atomic and easy to read. Break it up like so:

    switch (selectedTab) {
    case (Tab.SITES):
        renderSitesTab();
    case (Tab.CATEGORY):
        renderCategoryTab();
    case (Tab.DEMOGRAPHIC):
        renderDemographicsTab();
    case (Tab.ALL_SITES):
        renderAllSites();
    }
