[RESOLVED]Retrieve product number from SDF file

I have a sdf file, i wan to retrieve product numbers from the file. However, when i print out, it only printed out the first product number(02230416222D). There are supposed to be 2 products numbers, does anyone knows why my program only loop 1 time?
This is how the sdf file looks like:

Code:

---


  -ISIS-  02230416222D

 17 18  0  0  0  0  0  0  0  0999 V2000

......
$$$$//this is end of the first product
  -ISIS-  02230416222D

 17 18  0  0  0  0  0  0  0  0999 V2000
......
$$$$ //this is the end of second product

---

This is my java program:

Code:

---

Scanner inFile = new Scanner(new FileReader("merlin3.sdf"));
while(inFile.hasNext("-ISIS-"))
{
        String line = inFile.nextLine();
        String pdt = line.replaceAll("-ISIS-","");
        String pdtNo = pdt.trim();
        System.out.println(pdtNo);
}

---

Here is the solution:

Code:

---

while(inFile.hasNext()) {
        String line = inFile.nextLine();
        if(line.contains("-ISIS-")) {
                String pdt = line.replaceAll("-ISIS-","");
                String pdtNo = pdt.trim();
                System.out.println(pdtNo);
        }
}
