title: How and where to store expressions in variables
body: <p>Can I make expressions in Java and store them into a variable of Boolean datatype? So that I can use them in conditional use? If so please tell how.<br>
  Expressions like:<br>
  <code>(temp.name(0) &amp;&amp; temp.name(1))</code><br>
  and save them into a variable which can either be true or false.</p>
