Java c++ Reference question
<p>In c++ we use &amp; to represent pass by reference. Since objects are always passed by reference you do not need to use this &amp;? Or does it not matter?</p>

<p>How do java and c++ differ in pass by value and reference. Everything in java I thought is pass by reference but it is pass by value? Why is this? So is it primitives are pass by value while class objects are pass by reference?</p>
