<br />
Yes. If your method is called getList then you'd do<br />
<br />
Object o = getList().get(0); // get first element<br />
<br />

</div>

Yes. If your method is called getList then you'd do

Object o = getList().get(0); // get first element



<div>
&gt;&gt; public String getSomeString() {<br />
&nbsp; &nbsp; &nbsp;return someString;<br />
<br />
does it make any difference where i put the method?<br />
does somestring (or my list rather) need to be declared at a certain point in my code?<br />

</div>


>> public String getSomeString() {
     return someString;

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.
