Very simple parameter/argument "parser"

When I was trying to find a solution for a very simple parameter/argument parser, I found some sources in the www and combined it to s.th. you possibly find useful:

Code:

// predef vars
String playername = "";

// doing the hashmap
HashMap hm = new HashMap();
try {
for ( String arg : args ) {
    String[] tokens = arg.split(":");
    hm.put(tokens[0], tokens[1]);
} } catch (Exception e) { }

// select from params
if (hm.containsKey("player")) {
    playername = hm.get("player").toString();
}

Then you're be able to request every parameter with key and value.
For example:
/mycommand player:testplayer123 second:value key:value

Please don't comment my coding style, just take it or make it better
