Trying to find and print out a row from file

Question

I have a program that does several different things, one of them being this method to find an item in the file and display the attributes of that file (there are 3) in the row. For some reason, this is only printing out the first three strings in the file, instead of finding and printing the item I search for.

public static void findItem() throws FileNotFoundException {
 Scanner kb = new Scanner(System.in);

    FileReader reader = new FileReader("read_record.txt");
    Scanner fin = new Scanner(reader);
    System.out.println("Enter the sku of the dvd you wish to find.");
    String dvdSku = kb.next();


    while (fin.hasNext()){
        String nextString = fin.next();
        if (nextString == dvdSku); {
            String skuToFind = nextString;
            String titleToFind = fin.next();
            String lengthToFind = fin.next();
            System.out.printf("%-10s %-15s %10s %n",skuToFind,titleToFind,lengthToFind);
            break;
        }
    }
}

remove break statement, it will be able to search through out the file — Kishore, Nov 29 '13 at 20:03

Use equals or equalsIgnoreCase for comparing strings.

if (nextString.equals(dvdSku)){

Also remove the break statement that you have unless you want to stop on first match.

Also the semicolon after the if and before the brackets is an issue. – t0mppa Nov 29 '13 at 20:05
Actually it will compile and end the if. Then the stuff inside brackets will get called every time. – t0mppa Nov 29 '13 at 20:10
Ugh, stupid me. It's always a semicolon haha. Thanks! – Corey Nov 29 '13 at 20:10
