Hi guys just wondering, how can code a for loop to do the following:-

8:00
8:15
8:30
8:45
9:00
9:15
9:30
9:45
10:00
...
...
20:00

the following code does it hourly but how do i do it in 15min intervals? this code will be put in a JTable at col 0 with the heading "time" (making a time table...)

CODE

for(int row = 0; row < 12; row++)
{
    int t = row + 8;
    String val = t + ":00";
    table.setValueAt(val, row, 0);
}


I did a test for loop... and it works but how do implement this to my table??

CODE

for (int i=8; i<21; i++)
{
    System.out.println(i+ ":00");
    System.out.println(i+ ":15");
    System.out.println(i+ ":30");
    System.out.println(i+ ":45");
}

CODE

for (int i = START; i < END; i += 15)
    System.out.printf("%d:%02d\n", i / 60, i % 60);


Use the Formatter class to return a string with the times, and then iterate through the JTable, and set whatever equal to that string.
