Let suppose I have a method <pre class="prettyprint"><code>public int dummy(){ return 1; } </code></pre> and if I call this method by <pre class="prettyprint"><code>dummy(); </code></pre> not <pre class="prettyprint"><code>int a = dummy(); </code></pre> will it make any difference? why?

No, it wouldn't make any difference. We call a ton of methods from the JDK ignoring their outputs - List's <code>.remove(int index)</code> removes the element at a given index, and returns what element was removed. It is normal to ignore it and move ahead.

Is it necessary to store a value from a method which is retuning a value in java?
