You keep getting it, presumably, because you haven't fixed the mistake that produces it. Looks like you are missing an import for the Scanner class. –bmargulies Apr 27 '13 at 1:08 add a comment| 2 Answers 2 active oldest votes up vote 0 down vote accepted You need to import the Scanner before you use it: Scanner keyboard = new Scanner(System.in); Also I do not know if you forgot to paste it, but you also have to give a name to your class. For instance: public class Change { } share|improve this answer edited Apr 27 '13 at 1:14 Michael Petrotta 44.4k11108151 answered Apr 27 '13 at 1:11 danilojara123 9818 add a comment| up vote 1 down vote You need to impo

is what I have, and this is the error message: cannot find symbol symbol: constructor Scanner() location: class.java.util.Scanner And also, there is a problem with another one of my codes that I'm not sure about...: if(guess == http://stackoverflow.com/questions/16247270/how-do-i-fix-a-cannot-find-symbol-error-in-java-scanner secretWord) error message: Comparing String using =! or == not too sure about this one...anyways if anyone can help I would appreciate it. phintastic 1 post since Sep 2008 Newbie Member java 0 stultuske 1,049 8 Years Ago for using the Scanner class, don't you need to make an import of the class? import java.util.Scanner; concerning your second question: the == and != are indeed not the right way to check whether two https://www.daniweb.com/programming/software-development/threads/146227/can-t-find-scanner-class Strings are equal or not. a String is an Object, and should be compared using the method equals() (or, equalsIgnoreCase()) for instance: String guess = "guess"; String secret = "secret"; boolean test = guess.equals(secret); // test = false; if(!guess.equals(secret)) System.out.println("this line will be printed, since the two Strings are not equal"); 0 Alex Edwards 321 8 Years Ago The problem wasn't the import. It looked like the OP already had the import listed. The problem is that the Scanner class does not provide a "default" constructor for Scanner objects. For a list of proper Constructors for Scanner objects, refer to this link. The most common use for a Scanner object is the provide a way for pulling specific information out of a File or InputStream. Example-- import java.util.Scanner; public class MyScannerTest{ public static void main(String... args){ Scanner kb = new Scanner(System.in); System.out.println("Enter something, please... anything!\n"); System.out.println("\nYou entered: " + kb.next()); } } --though I think BufferedReader does the job much better than Scanner. Then again, each class solves a different problem in a similar way. This article has been dead for over six months. Start a new discussion instead.

I have this java program that converts measurements that the user inputs from a menu. When I compile it I get the following two errors that I've never seen before: Conversion.java:27: cannot find symbol symbol : variable keyboard location: class Conversion choice = keyboard.nextLine(); ----------^ Conversion.java:29: incompatible types Found : java.lang.String required: int switch (choice) --------^ 2 errors And here is my code below. I'm not sure how I could solve these errors...perhaps I worded something wrong. import java.util.Scanner; public class Conversion { public static void main(String[] args) { double meters; Scanner keyboard = new Scanner(System.in); System.out.print("Enter a distance in meters: "); meters = keyboard.nextDouble(); if (meters < 1) System.out.print("Please enter a positive number!"); menu(meters); } public static void menu(double meters) { //display a menu of choices for the user String choice; System.out.println("1. Convert to kilometers "); System.out.println("2. Convert to inches "); System.out.println("3. Convert to feet "); System.out.println("4. Quit the program "); System.out.println(); System.out.println(); System.out.println("Enter your choice: "); choice = keyboard.nextLine(); switch (choice) { case 1: showKilometers(meters); break; case 2: showInches(meters); case 3: showFeet(meters); break; case 4: System.out.println("Bye!"); System.exit(0); break; default: System.out.println("Not valid, try again please."); } } public static void showKilometers(double meters) { //calculate for kilometers Double kilo; kilo = meters * 0.001; System.out.println(meters + " meters is " + kilo + " kilometers."); } public static void showInches(double meters) { //calculate for inches double inch; inch = meters * 39.37; System.out.println(meters + " meters is " + inch + " inches."); } public static void showFeet(double meters) { //calculate for feet double feet; feet = meters * 3.281; System.out.println(meters + " meters is " + feet + " feet."); } } This post has been edited by macosxnerd101: 27 March 2011 - 10:59 PM R
