minute: Sign up Java error, cannot find symbol - class string up vote -1 down vote favorite I am trying to get my code to create the new constructor objects which I require to create a mobile phone object. I have tried naming the constuctor fields to create the object. UPDATE: I have amended string to be String, however now when I error cannot find symbol class intent update it I get the error: error: constructor Mobile(java.lang.String,int,int,java.lang.String,int,java.lang.String) is already defined in class Mobile This error comes up at the bottom of the page at: public Mobile(String MobilephoneType, int Mobilescreensize, int Mobilememorycardcapacity, String newserviceprovider, int Mobilecameraresolution, String MobileGPS) { What does this error mean? The code so far: /** * to write a simple java class Mobile that models a mobile phone. * * @author (Lewis Burte-Clarke) * @version (14/10/13) */ public class Mobile { // type of phone private String phonetype; // size of screen in inches private int screensize; // menory card capacity private int memorycardcapacity; // name of present service provider private String serviceprovider; // type of contract with service provider private int typeofcontract; // camera resolution in megapixels private int cameraresolution; // the percentage of charge left on the phone private int checkcharge; // wether the phone has GPS or not private String GPS; // instance variables - replace the example below with your own private int x; // The constructor method public Mobile(String mobilePhoneType, int mobileScreenSize, int mobileMemoryCardCapacity, String newserviceprovider, int mobileCameraResolution, String mobileGPS) { this.phonetype = mobi

cannot find symbol error cannot find symbol class hashtable "Cannot find symbol" errors generally occur when you try to reference an undeclared variable in your code. Consider the following example: public class Test { public static void main(String[] args) { int a = 3; http://stackoverflow.com/questions/19471477/java-error-cannot-find-symbol-class-string int b = 4; int c = 20; average = (a + b + c)/5.0; System.out.println(average); } } 1 error found: File: Test.java [line: 7] Error: Test.java:7: cannot find symbol symbol : variable average location: class Test Here, the variable average has not been declared-- you need to tell the compiler what the type of average is; for example: double average = (a + b + c)/5.0; Secondly, sometimes this error http://cs-people.bu.edu/dgs/courses/cs111-old/assignments/errors.html occurs because you are trying to reference a method in your code, but forget to include the parentheses that indicate a reference to a method, even when there are no parameters. For example: public class Test { public static void main(String[] args) { my_method; } public static void my_method() { System.out.println("Hello, world!"); } } 1 error found: File: Test.java [line: 7] Error: Test.java:7: cannot find symbol symbol : variable my_method location: class Test Here, the compiler is looking for a variable called my_method in the main method; instead, you want to initiate a method call to my_method: public class Test { public static void main(String[] args) { my_method(); } public static void my_method() { System.out.println("Hello, world!"); } } Thirdly, this error could also occur if you forget to import a Java package that you need to use. For example, consider the following program that reads in an integer from the user: public class Test { public static void main(String[] args) { Scanner console = new Scanner(System.in); int n = console.nextInt(); } } 2 errors found: File: Test.java [line: 3] Error: cannot find symbol symbol: class Scanner location: class Test File: Test.java [line: 3] Error: cannot find symbol symbol: class Scanner location: class Test The issue here is that the progot error "Cannot find symbol" I've read all questions related to this, but still I can't figure out how to solve this. My code https://teamtreehouse.com/community/declaring-new-variable-and-got-error-cannot-find-symbol - PezDispenser.java: public class PezDispenser { // creating an object with size 12 // final = no one can change this value public final int MAX_PEZ = 12; // private = if you are not the class you can access this use get method private String mCharacterName; // making a contractor with 1 argument public PezDispenser(String characterName) { // Use of "m" before characterName error cannot to define it as a member mCharacterName = characterName; } // properties public String getCharacterName() { return mCharacterName; } // jave-repl // :load - explore object by loading X.java file such as :load PezDispenser.java } Exmaple.java public class Example { public static void main(String[] args) { // Your amazing code goes here...

I got the same errors as you until I removed your //comments. Comments shouldn't matter but apparently the repl misread your code because of them.
