How to scanning files and assign values to a 2D array in java

Question

I'm a new learner to java and I'm scanning a .dat file and I want to print it out as a table in blueJ. My codes are as follows:

Scanner sc = new Scanner(new File ("test01.dat")); 
for (int r = 0; r < 6; r++){
    for (int c = 0; c < 3; c++){
        int temp = 0;
        temp = sc.nextInt();
        tri[r][c] = temp;
        System.out.print(tri[r][c]+" ");
    }
    System.out.println();
    sc.nextLine();
}

I almost get there but my problem is that my result printed out is 19 numbers including a zero at the end.(It was supposed to be 18 numbers with no zero at the end) How can I get rid of that zero? Oh and in addition, my input is just a column of 18 numbers and I'm changing it to a table with 6 rows and 3 columns. For more information, here is the link of my file: https://onedrive.live.com/redir?resid=B6E07F4C7635D773!4577&authkey=!AL9Zw4b4CWlS630&ithint=file%2cdat Thanks for all the comments and finally I found what I need~(^o^)~

Answer 1

The problem is using sc.nextLine after sc.nextInt.

Scanner sc = new Scanner(new File ("test01.dat")); 
for (int r = 0; r < 6; r++){
    for (int c = 0; c < 3; c++){
        int temp = 0;
        temp = Integer.parseInt(sc.nextLine().trim());
        tri[r][c] = temp;
        System.out.print(tri[r][c]+" ");
    }
    System.out.println();
}

This should fix it !
Note you file should have one integer per line.

Answer 2

Answer provided StackFlowed is correct. Just comment out "sc.nextLine()" in outer for loop. It'll make you skip one number after every row.
