[RESOLVED] I am confused..

I am trying this:

Code:

---

try(BufferedReader br = new BufferedReader(new FileReader("T.txt")); BufferedWriter bw = new

BufferedWriter(new FileWriter("T.txt"))) { 
                read = br.readLine();
                ArrayList ara = new ArrayList();
            do {
                        br.readLine();
                  ara.add(read);
                        }while(br.hasRemaining());

---

Error:

Code:

---

Test2.java:70: error: cannot find symbol
                        }while(br.hasRemaining());
                                  ^
  symbol:  method hasRemaining()
  location: variable br of type BufferedReader
1 error
complete!
Press any key to continue . . .

What am I doing wrong I've even imported the Buffer API package. I would really appriciate a nice apt explaination of what exactly the "." operator does. Because, I don't fully understand it. Or if you can explain it here. *edit* I suppose I understand that br.hasRemaining doesn't work, because bufferedReader doesn't have a hasRemaining method. I would still like a nice explainatoin of the "." operator.

Read the API for BufferedReader. There is no hasRemaining() method.

You can think of it as meaning the method or variable that is in the preceding class or object. ie

Code:

---

System.out.println("SomeText");

---

means the method called 'println' that is in the object referenced by the 'out' variable that is in the class 'System'
