Reflection - class.getConstructor question

Question

package my.util;
class Test {
String s;
int i;
public Test(String s, int i){}
I want to do the following
Class c = Class.forName("my.util.Test");
Constructor con = c.getConstructor(new Class[] { String.class, int.class});
Test t = con.newInstance(new Object[] {"al",5});
The above obviously won;t compile because I can;t pass primitives to the object array at the time of creating the instance and I cannot do int.class when getting the
constructor. How do I then use reflection to achieve the
above..?

Answer 1

The above obviously won;t compile because I can;t
pass primitives to the object array at the time of
creating the instance and I cannot do int.class when
getting the constructor.you can use int.class. this allows you to distinguish between constructors which accept primitive int versus those which might accept the java.lang.Integer type. but to populate the object array of actual arguments to the reflective invocation, you should wrap primitives in their corresponding wrapper type, e.g. int --> java.lang.Integer, char --> java.lang.Character, and so forth.
good luck,
