while until condition doesn´t work

Question

i want to write a little program, but don´t know why my loop isn´t working correctly.

while ((!ss.legal(myNumbers, colRand, rowRand, numRand)) || (triedNumbers.size() != 9)) {   
                System.out.println(triedNumbers.size());
//              if(triedNumbers.size()==9) break;
                numRand = getRandomNumber(1,9);
                if (!triedNumbers.contains(Integer.valueOf(numRand))) {
                    triedNumbers.add(Integer.valueOf(numRand));
                }

            }

The thing is the second condition. My syso-command tells me the size is already 9 but the loop doesn´t end?

If the random number is fine the legal method returns true . So the loop should end. If the size of the map gets 9, it should also end the loop because I am only checking the numbers from 1 to 9.

Answer 1

Replace || (or) with && (and). As it is even if the size is already 9 the loop will still continue as long as the first condition is true
