public class Hilo

int guess;
int num;
num=(int)(Math.random() *101+1);
guess= Console.readInt("Take a guess.");

else if (guess < num)

System.out.println("Your guess is too low. \n Please guess higher.");
}
else
System.out.println("Your guess is correct, good job.");

System.out.println("Thanks for playing the Hi-Low guessing game.");
ans=Console.readChar("Would you like to play again? (y/n)");
}while (ans=='y');
}
}
}


The error reads readInt() in console cannot be applied to (java.lang.String)
I am very new to java, so please explain in detail.

What is Console? It hasn't been define o stated in the porgram.

Thanks for the info.... but is Console in a class file or a JAR file or something else? You have to import it or instanciate the class in your program, before you can use it
