while loop help

hi , i created the game battleship but im supposed to end it after the 17th hit 5 hits for ship A 4 for ship B 3 for ship P 3 for ship D and 2 for ship S. What i did was to create a while loop
while i< 17
//my board is here
if (gameBoard.guessPosition(row, column)== true) {
i++;
}

but i realized that if i do that then if the user hits the same ship 17 times the game ends too. I dont know how to make it end after all of the ships have been hit. Any help will be appreciated. Thanks

An array of booleans set to true when that ship part has been hit, and a counter to keep track of how many times a value actually changes.
