&gt;&gt;will it reduce the efficiency of method??<br />
it should not, you are now making different kind of reference to the object.<br />

Hi All,<br />
<br />
I just get the doubt. Could you please clarify that<br />
<br />
java.util.List contains either strings or my own defined class instances<br />
<br />
now when I try to type cast them to Array, will it reduce the efficiency of method??<br />
<br />
<br />
I &nbsp;am type casting like this. List's size may vary from 1 to 100000<br />
<br />
(String[])list.toArray(new<wbr /> String[0]); &nbsp;<br />
<br />
&nbsp; &nbsp; &nbsp; &nbsp; or<br />
<br />
(IWdHttpRefernce[])list.to<wbr />Array(new IWdHttpRefernce[0]); &nbsp;<br />
<br />

Efficiency of typecasting

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.
