How do I incoporate buffered writer to my random guessing game?
0
I have a task where I need to incorporate buffered writer into my Java code as a way to restore the guesses if the program crashes. For example, the program would ask, "do you want to restore the same guesses you had?".
I am a bit lost on what to do. Any suggestions or help would be greatly appreciated.
import java.util.*;
public class Guess{
public static void main(String args){
Scanner scan = new Scanner(System.in);
String playAgain = "";
do {
int randomTarget = randomNumberGenerator();
int userInput = 0;
System.out.println("Welcome to the random number generator game!");
System.out.println("Enter a number between 1 through 10:");
int count = 0;
while (userInput != randomTarget){
try{
userInput = scan.nextInt();
}catch(Exception e){
System.out.println("Invalid type.");
count++;
String s = scan.next();
System.out.println(s + " is an invalid input. Try again");
continue;
}
if (userInput > randomTarget){
count++;
System.out.println ("Number too high!");
}else if (userInput < randomTarget){
count++;
System.out.println("Number too low");
}else{
System.out.println("Congratulations, you guessed correctly!");
count++;
System.out.println("It took you: " + count + " tries!");
playAgainQ();
try {
playAgain = scan.next();
} catch (Exception e) {
System.out.println(playAgain + " is an invalid input. Try again");
continue;
}
}
}
} while (playAgain.equalsIgnoreCase("y"));
System.out.println("Thanks for playing. Goodbye!");
}
static void playAgainQ() {
System.out.println("Do you want to play again? Type y for yes.");
}
static int randomNumberGenerator() {
Random randomNumber = new Random();
int randomTarget = (randomNumber.nextInt(10) + 1);
return randomTarget;
}
}

What do you mean by BufferedWriter? A Writer is just a mechanism of writing data to a file. In what state do you want to persist your data - as Objects, in some data interchange format (XML), or as pure text?

If the program crashes, any objects associated with the program will also be lost. If you want to save information for use in between sessions, consider writing guesses (or whatever) to a file, to be restored later by reading from the file. Look into JSON serialize/deserialize using the GSON library
