Regarding Class Loader

Question

Hi
I am loading a class dynamically and i am using classloader.My code looks like this and its working fine.
import java.lang.reflect.Method;
public class TestTwo{
TestTwo(){}
void Create() throws Exception{
     c.TestOne t ;
     ClassLoader cl = this.getClass().getClassLoader();
     Class cla = cl.loadClass("c.TestOne");
     t = (c.TestOne) cla.newInstance();
     System.out.println(t.getI());
     Method[] methArr = cla.getDeclaredMethods();
     for (int o=0; o< methArr.length; o++){
          //To get Public methods out of the class
     if(methArr[o].getModifiers()==java.lang.reflect.Modifier.PUBLIC)
               System.out.println(methArr[o].getName());
public static void main(String[] args){
     TestTwo t = new TestTwo();
     try {
          t.Create();
catch (Exception e) {e.printStackTrace();}
My doubt is i am having testone class inside this package (c.testone)and suppose i am placing the class testone somewhere else the code is not working fine..
My question is can we dynamically load a class dynamically from anywhere in my system.
thanks for your reply in advance

Answer 1

Even when loading classes dynamically, it still needs to be in the classpath. Of course it is possible to load classes outside of the classpath, but it's a bit more work and you still have to think of a way to find the class (in which case you might just put it on the classpath anyway).
The API mentions (in conjunction with ClassLoader) as an example a NetworkClassloader, where a class is loaded through a network and then constructed with defineClass() etc. You might want to start from there if you're still interested.
