Re: [TCLUG-DEVEL:216] Java - dynamically generate variable names

[Chris McKinley <lamfada@lugh.net>]

This problem just screams out for a container class.  One of the various hash
classes should work well.  Example:

Hashtable varHash = new Hashtable(20);  // set initial capacity to 20
String key_static = kwdph;
int arg_cnt = 1;
while(true)
{
	String key = key_static + String.valueOf(arg_cnt);
	varHash.put(key, parser.getStringParameter("phrase" + arg_cnt));
	if(varHash.get(key) == null)
		break;
	arg_cnt++;
}
