In java, a composite object cannot contain other objects. what does it means?
<p>I am confused with the following statement . Could anyone help me in understanding the following statement?</p>

<blockquote>
  <p>In java , a composite object cannot contain other objects. It can only have references to its constituent objects. Constituent Objects can be shared between objects and their lifetime can be independent of the lifetime of the composite object.</p>
