list - Java calling method from generic class -

is possible.

list<?> mylist = getmylist(); class cls = class.forname("com.lab.myclass"); cls = mylist.get(0); cls.getvalue(); 

create instance fully-qualified name of class , use declared methods?

no, if call class.forname, @ compile time know nothing returned class instance. don't know represents class; might interface example. in particular, if class , create instance of it, cannot call methods of except defined in object because, @ compile time, compiler cannot check whether these methods exist.

the 2 solutions:

first, can use reflection find out methods class has, , call these methods. cumbersome.

second, if use class.forname dynamically load classes @ runtime, know classes load. example, might know class implements interface. can cast result of newinstance interface , call methods defined in interface directly.

for example:

// in file plugin.java interface plugin {     void dosomething(); }  // in file main.java public class main {      ...     void runplugin() {         try {             class<?> pluginclass = class.forname("pkg.name.myplugin");             plugin plugin = (plugin) pluginclass.newinstance();             plugin.dosomething();         }         catch (...) {             // catch necessary exceptions         }     } }
