Getting Error / Cannot Find Symbol
Jul 23, 2014I 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.

Keep Getting Error Cannot Find Symbol

Cannot Find Symbol Error
Jun 12, 2014I 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.
Cannot Find Symbol Error
Sep 18, 2014I'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); )
Cannot Find Symbol Compile Error
Jul 23, 2014programming 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

Swing/AWT/SWT :: Compile Error - Cannot Find Symbol With SetDefaultCloseOperation

Print Grades Using Only Methods - Cannot Find Symbol Error
Nov 25, 2014The 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) {

GUI Dice Game Compilation - Cannot Find Symbol Error

Dummy Node In Doubly Linked List - Cannot Find Symbol Variable Error
Jun 5, 2012Im 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
Check For Upper Case Letters From User Input - Cannot Find Symbol Compile Error
Apr 15, 2015I 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();

An Error Occurred While Shelling Out To Javac - Matlab
Jan 26, 2015I am trying to extract a jar file from Matlab code using javac from Library Compiler (java package).
I have set JAVA_HOME to:
Java Code:
C:Program FilesJavajdk1.7.0_11 mh_sh_highlight_all('java');
and added to PATH:
Java Code:
C:Program FilesJavajdk1.7.0_11bin. mh_sh_highlight_all('java');
When I enter java -version in my console, I get java version jdk1.7.0_11 and running javac -version shows jdk1.7.0_11.
However, it seems that matlab could not find javac, thus, I am not able to compile my .m code into a .jar file. When I tried to compile .m code I got the following:
Java Code:
Error: An error occurred while shelling out to javac (error code = -1).
Unable to build executable.
Executing command: ""C:Program FilesJavajdk1.7.0_11binjavac" mh_sh_highlight_all('java');
This is the directory of my java bin folder and javac.exe exists : CProgram FilesJavajdk1.7.0_11binjavac.exe? What should I check in order to correctly link Matlab to Java?
Blackjack Program - Error Occurred During Initialization Of VM
May 21, 2014I've been trying to finish this blackjack program I have been making for my programming class, however, there are a few bugs I can't seem to iron out. It's a pretty short program, it's just that I'm an idiot and can't figure basic stuff like this out. Specifically, when I try and run it, I get this error:
Error occurred during initialization of VM
java.lang.OutOfMemoryError: unable to create new native thread

So, obviously I'm doing something horribly wrong.
