<div>
Weird that Netbeans doesn't give me a warning on the last one then ... just says the same as the second one: &quot;may split declaration into a declaration and assignment&quot;. &nbsp;So in 1.7, is the &lt;&gt;&nbsp;just shorthand because specifying the type again is simply redundant, and that there is never a time that the &lt;&gt;&nbsp;type in the assignment would ever differ from the &lt;&gt;&nbsp;in the declaration?

Weird that Netbeans doesn't give me a warning on the last one then ... just says the same as the second one: "may split declaration into a declaration and assignment".  So in 1.7, is the <> just shorthand because specifying the type again is simply redundant, and that there is never a time that the <> type in the assignment would ever differ from the <> in the declaration?

Easy question:<br />
<br />
ArrayList&lt;String&gt; alist = new ArrayList&lt;String&gt;();<br />
ArrayList&lt;String&gt; alist = new ArrayList&lt;&gt;();<br />
ArrayList&lt;String&gt; alist = new ArrayList();<br />
<br />
All of the above SEEM to work identically. &nbsp;Is that indeed the case? &nbsp;Netbeans indicates that the first one is &quot;redundant&quot; and is happy with the last two. &nbsp;Which is <i>most </i>correct, or is there one that is considered just good programming practice? &nbsp;Is there any circumstance where one would be required over another?

Easy question:

ArrayList<String> alist = new ArrayList<String>();
ArrayList<String> alist = new ArrayList<>();
ArrayList<String> alist = new ArrayList();

Easy ArrayList Question

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
