9,050 PointsIncompatible types error - im so confused.
Im Having trouble getting past this part in my code contained in the prompter class
any ideas where ive gone wrong?
this is the error:
public void addItem(Product item, int quantity) {
System.out.printf("Adding %d of %s to the cart.%n", quantity, item.getName());
/* Other code omitted for clarity */
}
public void addItem(Product addedItem) {
addItem(addedItem, 1);
}
my code is below:
import java.io.Console; // clas were importing from java IO
public class Prompter{
private Game mGame; //member variable
public Prompter(Game game){
mGame = game;
}
//example.charAt(0);
public void play(){ // limit scope to the story were working on
while(mGame.getRemainingTries() > 0) {
displayProgress();
promptForGuess();
}
}
public boolean promptForGuess(){
Console console = System.console();
boolean isHit = false;
boolean isValidGuess = false; //starts false
while(! isValidGuess){
String guessAsString = console.readLine("Enter a letter: ");
try{
isHit = mGame.applyGuess(guessAsString);
isValidGuess = true;
} catch (IllegalArgumentException iae){
console.printf("%s. Please try again.\n", iae.getMessage());
}
}
return isHit;
}
public void displayProgress(){
System.out.printf("You have %d tries left to solve: %s\n", mGame.getRemainingTries(),
mGame.getCurrentProgress());
}
}

and its focusing on the below line of code
isHit = mGame.applyGuess(guessAsString); ^

1,409 PointsWhy did you do that Nicolas Hampton? The code should look like:
isHit = new mGame.applyGuess(guessAsString);
Your code would give errors if you put that in it.

44,638 PointsWhen you declare and initialize your console, you have to add "new" to the code. Other than that, it's really hard to read what's going on there, next time surround your code with "java" and "
" so it comes up in a black code box for clarity. Anyway, the declaration should look like this
Console console = new System.console();
