java - How do I use reflection to get data out of a hibernate object? -

here example of issue having using reflection. simple case, need dynamically build method name on fly... simple case can not work!

client1 cdata = (client1) session.get(client1.class, 1); int ctype = cdata.getclienttype(); int ctype2 = -1;  method method[] = null; method getctypemethod = null;  try {   method = cdata.getclass().getmethods();   (method m : method){     system.out.println(m.getname()); // displays getclienttype   }    getctypemethod = cdata.getclass().getmethod("getclienttype", int.class);   if (getctypemethod != null){       ctype2 = (int) getctypemethod.invoke(cdata,  int.class);   } } catch (exception e) {   e.printstacktrace(); }         assertequals(ctype,  ctype2); 

the line:

getctypemethod = cdata.getclass().getmethod("getclienttype", int.class); 

always throws exception: java.lang.nosuchmethodexception: client1.getclienttype(int)

the method getmethod receives param classes, not return type, getclienttype receive int?

if not, try:

cdata.getclass().getmethod("getclienttype");
