    copied!<p><br> I guess this question that would have already been asked here. I searched but could not find anything similar. So here goes --<br> I have a custom data object <code>Method</code> and <code>Method</code> is as follows --</p> <pre><code>public Class Method { List&lt;String&gt; inputParameters; String resultVariableName; } </code></pre> <p>Now i have a <code>LinkedList&lt;Method&gt;</code> which acts as a repository of <code>Method</code> objects.</p> <p>Given a <code>Method</code> object is there a way in which the correct index of the <code>Method</code> object can be concretely determined.<br> My question arises from the face that <code>LinkedList</code> class has an <code>indexOf</code> routine but this routine returns the first occurrence of the object but then there is no given that 2 copies of <code>Method</code> object can not reside in the <code>LinkedList</code>(right ?)<br> Would tagging every <code>Method</code> object as I add it to the <code>LinkedList</code> solve my purpose and if so is there an ideal way to do it ?</p> <p>EDIT :<br> Explaining my use case a little further.<br> My code basically reads a Velocity template top-down and creates <code>Method</code> objects. One <code>Method</code> object is created for every velocity routine encountered. This explains why the same element can be stored at multiple indices in the <code>LinkedList</code> as there is no real restriction on how many number of time a <code>Velocity</code> routine is called or the inputs/results provided to the <code>Velocity</code> routine.</p> <p>Now, i have a UI component, one <code>JButton</code> per <code>Method</code> object reference in the <code>LinkedList&lt;Method&gt;</code> by using which the user can click and edit the <code>Method</code> object.</p> <p>Thus i need to know which exact <code>Method</code> object reference to edit in the event that same elements reside twice or more number of times in the <code>LinkedList&lt;Method&gt;</code></p>
