Conditional Statements

[Werner Otto]

Problem:
class I {
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.println(i + "," + j);
}
}
Answer: 8,4
Can anyone explain to me how to reach this answer?

if 8,4 is what you want to get, all you need to change is:
while(i-- < 7) --> while(i < 7)
......I think...

Werner, your program had two errors. First, braces were out-of-balance after the else/if statement. Second, you were missing a semicolon after the i++ statement. Here is corrected version of your program:
class I {
public static void main(String[] args) {
int i = 0, j = 9;
do
{
if (j < 4) {
break;
} else if (j-- < 7) { // added this brace
continue;
}
i++; // added this semicolon
} while (i++ < 7);
System.out.println(i + "," + j);
}
}
After making this fixes, I got the output 8,4, as you suggest.

Ok, now that we have the syntax correct, and we agree that the answer is 8,4.
Can someone please explain to me the logical sequence of exection that this
loop will follow, resulting in 8,4.
