When to construct and when to throw an Exception?

Question

I have searched the forums but couldn't find anything specific to this.
Example code:
public exampleObject{
//constructor
public exampleObject()throws Exception{
public example2Object{
//declaration
private exampleObject = new exampleObject();
In JDK1.3 the compiling of example2Object throws an Exception
In JDK1.4 it doesn't throw an exception.
Why.......Should I not be constructing these objects in the declaration?
Thanks

I don't quite get you; the compilation doesn't throw an exception, does it? Possibly it may signal an error.
If I'm not wrong, your example is exactly the same as this:
public example2Object{
//declaration
private exampleObject;
//constructor
public example2Object() {
this.exampleObject = new exampleObject();
Thus, I believe that the constructor could throw an Exception (which it's signature doesn't say). It is generally a good idea to instantiate new objects in the constructor, instead of in the declaration of object variables. That's my opinion though...
