![]() Here's a loop that uses step to skip a few values in the desired range: for(int i = 0 i i i + 3) //functional However, there's a simpler solution, the iterate() method of IntStream. At first thought, to skip some values we may be tempted to use the filter() method on the stream. This method returns a stream that will generate one value at a time for values within the specified range. When looping over a range of values, one at a time, the range() method of IntStream came in handy to implement in the functional style. In this article we'll see how to take on loops that are a bit more complex-when we have to step over some values in an interval. Hint: We can do () in the inner for loop, and do () at the end of the outer for loop so that it starts a new line after each row has been printed.In the previous article in this series we looked at converting simple loops written in the imperative style to the functional style. Hint: If we do (), then all of the positions are on one line. ![]() Hint: If we do (), then each position is on a new line. Inside our function, we need to print out each position on our board. We don’t need to return anything since the function is simply printing out the board. Hint: We need to pass in the board 2D array in order for the function to be able to print it. In order for our function to draw the board and print it out, do we need to pass a parameter into the function? Do we need to return anything? Step 3: Create a function that draws the board and prints it out like a 3x3 square. We store their input in a String called p1. Then, we initialize our Scanner variable by making a new ScannerNext, we print out a message asking the user to type in their name using (). Step 2: Ask the users for their names.įirst, we import the Scanner to help us get user input by adding import to the top of our program. Inside both for loops, we can set board equal to a dash. Hint: We can use a nested for loop to iterate through each position on our board. Now we have to fill our board with dashes. Hint: We can use the following line of code to make a 3x3 array of chars: char board = new char We need to make a 2D array of characters, which can be x, o, or. How do we do each of these steps? Step 1: Create a 3x3 array to represent the tic tac toe board and fill it with dashes.
