for (int i = 53; i >= 45; i -= 2)

Reason

Loop (i > 45; i -= 2): The loop starts at 53 and decreases by 2 each time. The values are 53, 51, 49, and 47, which totals 4 iterations before the condition i > 45 becomes false.
Loop (i < 57; i++): The loop starts at 53 and increments by 1 each time. The values are 53, 54, 55, and 56, which totals 4 iterations before the condition i < 57 becomes false.
Loop (i >= 45; i -= 2): The loop starts at 53 and decreases by 2 each time. The values are 53, 51, 49, 47, and 45, which totals 5 iterations before the condition i >= 45 becomes false.
Loop (i >= 45; i--): The loop starts at 53 and decreases by 1 each time. The values range from 53 to 45 inclusive, which totals 9 iterations.

x = 10; y = 20;
do
{
    x++;
    y++;
} while (x<=20);
System.out.println(x * y );
