class H {
  public static void main (String[] args) {
    int i = 0, j = 9;
    do {
      if (j < 4) {
        break;
      } else if (j-- < 7) {
        continue;
      }
      i++;
    } while (i++ < 7);
    System.out.print(i + "," + j);
  }
}

the output:8,4
can you tell me why?

As you step through the do loop, when you get to the expression j-- < 7, remember (or save) the current value of j, decrement j, then use the saved value of j to test j < 7. When you get to the expression i++ < 7, remember (or save) the current value of i, increment i, then use the saved value of i to test i < 7.
Here is the first time through the loop:
evaluate 9 < 4
decrement j to 8 before evaluating 9 < 7
increment i to 1
increment i to 2 before evaluating 1 < 7
