Getting class properties

Question

hi can anyone tell me how to get setters from a class ??
a little example can be very helpful thanx !

Answer 1

Once you get the Class object you can user the getMethods call to get a list of methods available. Then you can inspect the methods for the one's that look credible.
import java.lang.reflect.*;
Class cls = theObject.getClass();
Method [] methods = cls.getMethods();
int i;
for(i = i; i < methods.length; i++) {
  Method m = methods;
if(m.getReturnType() == VOID.type && // setters have no return
m.getName.subString(0, 3).equals("set") &&
m.getParameterTypes().lenght == 1) {
// then m is probably a setter
To use a setter found in this way use
m.invoke(theObject, new Object[]{
   .. parameters ..});
