100 objects with one attribute each will eat more space. Anyways both are memory inefficient.

A lot of it depends on the attribute type. If a single object has 100 attributes, but each attribute is itself an object, you're talking 101 objects total. However, if all 100 objects are primitives, they'll all be housed within the containing object and you'll have 1 large object.

But I wouldn't design an application strictly on this basis anyway. First, I'd determine if I really needed 100 of either.

To throw a random answer in, if you have 100 String objects that are exactly the same, depending on how you created them you will only be using the space of one String on the heap.
