I have used class.forname() function for creating objects dynamically in eclipse. But for paramaterized constructor i had to class.getconstructor function() for which i need to know the datatypes of constructors.
So, i want to know the way of getting datatypes directly in constructor and use them in class.forname() and class.getconstructor().
This is code which i hv used:
public class ClassOne {
public static void main(String[] args) throws ClassNotFoundException, NoSuchMethodException, InstantiationException, IllegalAccessException, IllegalArgumentException, InvocationTargetException {
int param1 = 20;
String className = "ClassTwo";
Class cl = Class.forName(className);
Constructor con = cl.getConstructor(int.class);
Object xyz = con.newInstance(param1);
System.out.println(((ClassBase)xyz).getA());
}
}

This is pretty just a Java reflection question, isn't it? It's got
nothing to do with Eclipse. You might try javaranch.com, jguru.com or
stackoverflow.com. This forum isn't for what you do with Eclipse, but
how you use Eclipse and trouble using it.
Cheers.
