People will use a switch case statement to check for all but one choice and then catch that last one in the &#8216;otherwise&#8217; block of their code.  However, if there is unexpected inputs, the &#8216;otherwise&#8217; will fire when it should not.  \r\n\r\n<p>\r\n<p>\r\nThis video shows a technique for catching this problem.  It is important to catch these errors from unexpected inputs immediately, because they can have effects on your code much farther down the line.  When this happens, it would be hard to trace back to the cause.\r\n<p>\r\n<p>\r\n\r\n\r\n<div><div class=\"row\"><div class=\"col-xs-12 containing-block\"><div class=\"bc-outer-container add_margin_20\"><videoplayer><div class=\"video-js-container\"><video data-video-id=\"3877436967001\" data-video-category=\"blog\" data-autostart=\"false\" data-account=\"62009828001\" data-omniture-account=\"mathwgbl\" data-player=\"rJ9XCz2Sx\" data-embed=\"default\" id=\"mathworks-brightcove-player\" class=\"video-js\" controls><\/video><script src=\"\/\/players.brightcove.net\/62009828001\/rJ9XCz2Sx_default\/index.min.js\"><\/script><script>if (typeof(playerLoaded) === 'undefined') {var playerLoaded = false;}(function isVideojsDefined() {if (typeof(videojs) !== 'undefined') {videojs(\"mathworks-brightcove-player\").on('loadedmetadata', function() {playerLoaded = true;});} else {setTimeout(isVideojsDefined, 10);}})();<\/script><\/div><\/videoplayer><\/div><\/div><\/div>\r\n <\/div>\r\n","protected":false},"excerpt":{"rendered":"<div class=\"thumbnail thumbnail_asset asset_overlay video\"><a href=\"https:\/\/blogs.mathworks.com\/videos\/2013\/03\/25\/using-otherwise-to-throw-errors-in-a-switch-case\/?dir=autoplay\"><img decoding=\"async\" src=\"https:\/\/cf-images.us-east-1.prod.boltdns.net\/v1\/static\/62009828001\/b0c9d9f3-e136-45d9-960a-5b7ab9a1b481\/73b98901-dcd1-46c1-a1ac-4b902bb5d640\/1280x720\/match\/image.jpg\" onError=\"this.style.display ='none';\"\/>\n      <div class=\"overlay_container\">\n      <span class=\"icon-video icon_color_null\"><time class=\"video_length\">1:46<\/time><\/span>\n      <\/div>\n      <\/a><\/div><p>In some code there is an enumerated set of choices.
