Scanner is not reading properly.

Question

Hi,
I am using Java Scanner to read-in some numbers from a file.
It is skipping some of the inputs randomly and is not reading sequentially..
What may be the issue here?

Hi,
I am pasting my scanner code below,
           File template = null;
            FileReader read = null;
            BufferedReader buffRead = null;
        Scanner scan = null;
        try
            template = new File(templateFile);
            read = new FileReader(template);
            buffRead = new BufferedReader(read);
            String[] values = null;
            String line = buffRead.readLine();//discard the first line
             scan = new Scanner(buffRead);
               JLE = scan.next();
                JTE = scan.next();
                NOSECT = scan.next();
                KIN = scan.next();
            scan.close();
            buffRead.close();Here is my input file data,
Some title here
28 73 28 11 5000 14 52 12 28 0 24 1250 0
1 11 3 3 2 1 0 9 10 0 1 0
3 3 3 9 9 9 1 3 1
0.00000 0.00000
0.00000 0.00000 0.00000 0.00000 0.00000 0.00000 0.00000 0.00000

0.00000 0.00000 0.00000 0.00000 0.00000 0.00000 0.00000 0.00000

In my code I am removing the first line, i.e title by using buffRead.readLine() and discarding it.
And later I start reading the actual data into some String variables.
I have found that this works sometimes.
Ideally JLE & JTE should be initialised to 28 and 73 respectively (starting numbers in input file).
But many a times JLE takes value 73 and further used variables reads into values in some random pattern.
What is the problem in my code?
regards,
Praveen
