Hashtable lookup safety net!

How would I ensure my code didn't crap out if the key I use in my hashtable didn't exist?

Map <String, String[]> map = new HashMap<String, String[]>();

map.put("en_US", new String[] { "NA", "US"});
map.put("en_MX", new String[] { "NA", "MX"});

I'm surfacing via EL in the page.

var s_account="<%= map.get(currLocale)[0] %>"

How do I protect against a value not in the hashtable busting the code? Something like a default value in a switch statement.

As I tried to point out in your previous question
https://www.experts-exchange.com/Programming/Languages/Java/J2EE/JSP/Q_23431554.html 
an EL expression is
${"EL"}
><%= map.get(currLocale)[0] %>  
is called a JSP expression element.
