Cloning the class object

Question

Hi
I have a class which looks something like this:
class A
String name = null ;
int age = 0 ;
Object a = null
Object b = null ;
The Object classes could be any types including Dates etc but it is not fixed and so I am using object. The problem is that I also want to copy this class. Now I am writing my own constrcutor to make a copy object but there is no clone() method available for object. The api shows one but it doesn't work.
Any idea what the problem is or how I may copy a raw object?
Cheers

go through this example
Cloning an Object
class CloneClass implements Cloneable
public CloneClass()
public Object clone()
Cloneable theClone = new CloneClass();
return theClone;
public String toString()
return "Hello";
public static void main(String[] args)
CloneClass myObject = new CloneClass();
System.out.println("MyOjbect: "+myObject);
CloneClass myObjectClone = (CloneClass)myObject.clone();
System.out.println("MyObjectCloned: "+myObject);
//Arrays are automatically cloneable:
int[] ints = new int[]{123, 234};
System.out.printf("%s\n","Array Before Clone ...");
for(int i:ints)
System.out.printf("%d,\n",i);
int[] intsClone = (int[])ints.clone();
System.out.printf("%s\n","Array After Clone ...");
for(int i:intsClone)
System.out.printf("%d,\n",i);
}
