Is create possible to dynamic object?

Question

I want to creating dynamic object.
For example.
class A{
public static void main(String[] args){
testObject("Test");
public static void testObject(String obj){
Class c = Class.forName(obj);
obj o = c.newInstance();
I define object type to use variable obj.
Is it possible?
obj o = c.newInstance();

Still don't understand your question. Maybe this will help:
public class TestNewInstance
     public static void main(String args[])
          throws Exception
          Object o = createNewInstance("java.lang.StringBuffer");
          StringBuffer sb = (StringBuffer)o;
          sb.append("I just created a StringBuffer");
          System.out.println(sb.toString());
     public static Object createNewInstance(String className)
          throws Exception
          return Class.forName(className).newInstance();
}Notice how the code looks better when you use the "Code" tags as explained above?
