Thread: Manual Memory Management

How can one allocate an object in a function with a new command and add it to a list, and keep it even after the function returns?
To be more precise, here is the C++ equivalent:

void myfunction()
{
MyClass* myobject = new MyClass(...);
mylist.add(myobject);
}
 
void someOtherFunction()
{
MyClass* myobject = mylist.at(2); // The object has not been deleted
}

At some point, I would simply call

delete myobject;

to deallocate my object when I wouldn't need it anymore

I tried doing the same with Java, but my object must be getting deleted when the function terminates because I get a null reference exception

void myfunction()
{
MyClass object = new MyClass();
mylist.add(object);
}

Does anyone know the way I can do this in Java? Also, how can I delete the object?

Thank you Norm
