Below are three methods: checkValidInput, getCoordinates and play. Looking at checkValidInput, I feel it is very longwinded and would like to modify by using a try/catch block for user input. How is this occomplised? Would I be able to get rid of checkValidInput method with a try/catch? Any code to help me out would be great. public boolean checkValidInput(String input){ ArrayList<String> numList = new ArrayList<String>(); for (int i=0;i<10;i++){ numList.add(""+i); } String[] coordinates = input.split(" "); //returns false if there are not 2 strings if (coordinates.length!=2){ return false; } //returns false if first is String is not in between A and J if(coordinates[0].charAt(0)<'A' || coordinates[0].charAt(0)>'J') return false; //returns false if the second string is not a single digit number for (String str: coordinates[1]){ if (numList.contains(str)==false){ return false; } } //returns false if the coordinates have already been shot at int row = Integer.parseInt(coordinates[0]); int column = Integer.parseInt(coordinates[1]); if (this.availableSpot[row][column]==false){ return false; } return true; }

public int[] getCoordinates(String input) { int[] coordinates = new int[2]; String[] strList = input.split(" "); int row = (int) strList[0].charAt(0) - 65; int column = Integer.parseInt(strList[1]); coordinates[0] = row; coordinates[1] = column; return coordinates; }

public void play() { print(101); print(1); ocean.randomShipDeployment(); boolean isGameOver = ocean.isGameOver(); sc = new Scanner(System.in); //printOcean the ocean and start the game ocean.printOcean(); print(3); while (!isGameOver) { print(2); String input = sc.nextLine(); //check if input is valid while (!checkValidInput(input)) { print(99); input = sc.nextLine(); } //get coordinates and fire int[] coordinates = getCoordinates(input); int row = coordinates[0]; int column = coordinates[1]; ocean.shotFiredAtLocation(row, column); availableSpot[row][column] = false; isGameOver = ocean.isGameOver(); ocean.printOcean(); print(3); print(100); } //printOcean info saying you win print(4); print(5); }
