So there is a

Array<Student> called stu

that has 2 student objects in there [0], [1]

One of the elements that Studet[0] has (as well as Student [1]) is

String sid which is equal to "2345"

Studet[0] also has double Q1 = 95.0

1) String ut = stu[0].sid; // Why it does not give me the sid value "2345"?

My goal is to get the sid value of stu[0]?

What are my options here?

Please don't create duplicate threads. Post questions related to your first thread in that thread. As for your question, you should try using a debugger. Without the code in full, there's no way to know what's causing the problem.

If the class Student has a field name sid, and you've got an array of Students named studentArray, then studentArray[0].sid is want you want.

Is this supposed to be an ArrayList<Student> or a Student[]?

If you're using ArrayList<Student>, you cannot use brackets to retrieve objects, you have to use the get method.
