You have 2 simple approaches:<div><ol><li>Insert all your Students as facts and create regular rules like <br><i>Student(name == 'something')</i></li><li>Use the <i>from</i> keyword: <br><i>$c: ClassA ()<br>Student(name == "something") from $c.students</i><br>

Hi,<br>
<br>
I'm inserting an Object calld ClassA into the working memory. Which has got it's students in an ArrayList<br>
<br>
Like this...<br>
<br>
public class ClassA {<br>
<br>
private String RoomNo;<br>
private ArrayList<Student> students;<br>
<br>
...<br>
<br>
}<br>
<br>
public class Student {<br>
<br>
private String name;<br>
private String rollNo;<br>
<br>
...<br>
<br>
}<br>
<br>
Now, i've to write a rule to find a particular student with his role number and fetch his name to make some decisions.<br>
<br>
I don't know to write a rule to access an Object's data member of type ArrayList and find a match. Please help.<br>
<br>
Thanks in advance.<br>
