Cannot Find Symbol Error
Jun 12, 2014
I thought I have been getting this right, but I keep getting stuck on this one error. Here is my code. Why it keeps getting a 'cant find symbol' error?
// import statements
import java.util.Scanner;
// class declaration
public class GradeConverter
{
// main method declaration
public static void main(String[] args)
{
// display a welcome message
[code]....
It is just a simple input a number between 1-100 and it spits out the letter grade.

I have written the below program and while compiling i am getting error. The program and error details goes as follows,
//compute distance of light travels using Java long variable.
class Light {
public static void main(String args[]) {
int lightspeed;
long days;
long seconds;
long distance;
[code]....
I have given the Java file name as 'Light.java'. I have also verified the availability of the java file and compilation path. both are matching. Also, Java file name and class name defined are also same.

I'm picking up Java for a class, and having prior C++ knowledge this stuff has been fairly straightforward with the exception of trying to learn the whole IO system in this language.
className.java:line_number: error: cannot find symbol
myList.add(input);
^
I have dealing with this error left and right after picking up this language, and I can never seem to figure out what it's trying to tell me. I've heard people say it's referring misspelled objects or methods, but I've double and triple checked my code and that never seems to be true for me.I'm trying to make a small program which will allow me to play with the LinkedList object so I can gain some familiarity with how they work in Java, and I have this code so far:
import java.io.*;
import java.util.*;
public class playWithLists {
public static void main(String[] args) throws Exception {
//List<String> myList = new LinkedList<String>();
LinkedList myList = new LinkedList();
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String input = "";
[code]....
The compiler is giving me an error at line 16 (specifically: myList.add(input); )

programming altogether and after almost reaching half way in the 'Head first java' book I decided to try and apply some of what I've learnt so far and write my first 'Object orientated' program. As this is pretty much the first program I've ever written, I decided to write a program to ask for two integers and add them both together and then present them to the user (the goal eventually being a basic fully working command line calculator with +,-,* and /. I'm expecting many compile errors but not the following errors below.
I have three .java files contained within a folder and after trying to figure out how to compile all three files (as they use one another) all at once, I came across this ---> javac *.java
so I typed this in the command line whilst in the directory containing the three files assuming *.java is the best approach and then I receive the following errors:
inputOutput.java:10: error: cannot find symb
c.addition() = intIn.nextInteger();
^
symbol: variable c
location: class inputOutput

See code.

public class CQ1v1{
public static void main(String args []) {
Scanner in = new Scanner (System.in) ;
String name = "";
System.out.println("Welcome to the Interrogator") ;

When I compile getting
CQ1v1.java:12: error: cannot find symbol
x = in.nextLine ();

symbol: variable x

I am stuck. It seems like I have done everything by the book but I keep getting the same error: cannot find symbol. The error is specifically addressing lines 9, 10, and 11 in the Alien class file. All that is supposed to happen is an output of information for the two types of aliens.
Java Code:

This is likely a simple matter, but my error is confusing given the line it flags matches a working project I have. I get the following error on line 6 in the Controller:

The program is just a simple one to print grades using only methods. The problem is Im trying to use a returned value in another method but the compiler keeps telling me it cannot find the symbol "mark". the problem areas are marked in blue. I am basically trying to input a value into the keyboard and then use it in another method.
public static void main(String[] args) {
printTitle();
enterMark();
gradeCalculator(mark);
printGrade();

I'm having some difficulty getting this GUI dice game to compile. I'm using javac and notepad++ for this and I'm getting the following errors:
DiceGame.java:34: error: cannot find symbol
die2label = new JLabel();
^
symbol: variable die2label
location: class DiceGame
[Code] ....
4 errors
My code is as follows:
import java.awt.*;
import java.awt.event.*;
import java.util.*;
import javax.swing.*;
import javax.swing.event.*;
public class DiceGame extends JFrame

I'm sure the problem is something trivial, but I guess that's all part of the learning process that I have to go through.

Im running into some problems with the Java compiler. This is my code:
public class DoublyLinkedList<T> implements SimpleList<T> {
protected Node dummy;
protected int n;
public DoublyLinkedList(){
dummy = new Node();
dummy.next = dummy;
dummy.pre = dummy;
n = 0;
[Code] ....
I want to use a dummy node in my implementation of the Doubly Linked List, so it will be easier to code all the methods I need to write. I keep on getting a problem with line 14 and 15:
dummy.next = dummy;
dummy.pre = dummy;
// cannot find symbol variable next (compiler error)
// cannot find symbol variable pre

I decided to code this quiz I took in class about asking the user to input a string and the code is suppose to check for upper case letters. If a upper case letter is found, it should increase a count by one. Once the check is done, it should display the number of uppercase letters. For some reason I am getting this weird compile error stating that symbols can't be found...
Java Code:
import java.util.*;
import java.lang.*;
public class StringCheck{
public static void main(String[] args){
Scanner input = new Scanner(System.in);
System.out.println("please enter a string: " );
String s = input.nextLine();
