for loop?

Question about the task

Resolved

I solved this task with a while loop. The conditions also allow a for loop, but I can't figure out how to to it with a for loop. Anyone knows? Thanks in advance :)

useful

for (;;) { ........... (the same instructions as in WHILE(true) loop) }

solution

The for loop isn't that pretty.

BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
        int total = 0;
        int number;

/*
        for (number = Integer.parseInt(reader.readLine()); number != -1; total += number, number = Integer.parseInt(reader.readLine()));
*/
/*
        while ((number = Integer.parseInt(reader.readLine())) != -1) {
            total += number;
        }
*/

        for (number = 0; number != -1;) {
            total += number;
            number = Integer.parseInt(reader.readLine());
        }
        System.out.println(total);

number is declared in line 3 cause of the while loop. Othewise it could have been done in the for loop header.
