I'm doing a course on java but cant seem to get my servlet to compile i keep getting this error im seriously stressed out iv missed my dead line

I am using textpad to compile and Tomcat as a webserver...
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
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:
cannot find symbol v.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); ...........................................^ (carrot at the J)
My view file:
import java.awt.*; import javax.swing.*; import java.awt.event.*; public class View extends JFrame{ private JLabel lbl; private JButton btn;
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();
In reference to the book "Head First Servlets and JSP, 2nd edition", chapter-3(), page-81, the command to compile the servlet file to the desired location is
(from the same directory as can be confirmed from the attachment of screenshot of error). this code is in accordance to the location of the respective files in my system, in particular the servlet-api.jar file.
After doing this, my computer is showing the error : file not found.
How do I resolve this? Actually, I don't understand completely what this code is trying to accomplish.
I am having trouble compiling my simple java program, i keep having this "cannot find symbol"Untitled.jpg but the ODD thing is when i tried to run my code through online java compiler like Ideone.com it compiles perfectly fine. "Check it here".is it because of my jdk? I use the latest jdk 8. and the book I'm following is "Head First Java"..here's my code
My assignment is to create an ObjectOutputStream object mapped to a binary output file named "ItemRecord_binary.txt". So far I've created a ItemRecord class with a constructor with getters and setters and a override toString method. It compiled. This ItemRecordReport class does not compile because of a can't find symbol error. Here is the code:
import java.io.*; import java.io.IOException; import java.io.ObjectOutputStream; import java.util.Scanner; public class ItemRecordReport { private ObjectOutputStream output;
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 was given the Java code for a project and I am supposed to build unit tests to test the performance of seven sorting algorithms and I am getting the following error in my Lab1Test file...cannot find symbol: method sorta(int[]) location: class Lab1Test.
I keep getting errors, cannot find symbol. Not sure where I am going wrong.
java:139: error: non-static method integerPrompt(String,int,int) cannot be referenced from a static context int regNumber = integerPrompt("Enter registration number", 100, 5000); ^ Program7.java:145: error: cannot find symbol theSubject = integerPrompt(SubjectsPrompt, 1, SubjectQty); ^ symbol: variable theSubject location: class Program7
Java Code:

I have the following code snipet and I get the following errors
interface expected here [javac] private class fileFilter implements FileNameExtensionFilter{ [javac] ^ cannot find symbol [javac] symbol : method fileFilter(java.lang.Object) [javac] location: class gui.components.StartupDialog
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 an Input Box in which the user is supposed to enter the answer to a sum, when the answer is equal to the correct answer I want to show a MessageBox that tells them they've got it correct. But when I run the project it crashes saying it 'cannot find symbol',
Heres the code too:
import javax.swing.*; import java.util.Random; import java.util.Scanner; public class SwingInputExample { public static void main(String args[])
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); )
import javax.swing.*; public class opt { public int code[]; public static void main(String[] args) { int xxx = 1;
[Code] ....
Where did I did wrong cus I keep getting these errors: What do I need to do to fix the errors?
F:>javac opt.java opt.java:25: error: cannot find symbol cd.checkDeclare<zz>; ^ symbol: method checkDeclare<String> location: variable cd of type code[] java:32: error: cannot find symbol
i'm working on a "name sorter" program and i want it so when i add names and such to the list box i can click sort and it sorts the names in A,B,C format.Here is my code:
I'm using Netbeans FYI and a java desktop application. Also, i have looked everywhere and even my teacher has had to look further into it, i really want to get it to work.
I am using javac -d WEB-INFclasses WEB-INFclassesdemoServlet4ListenerTest.java and javac -d WEB-INFclasses WEB-INFclassesdemoServlet4MyServletContextListener.java to compile the classes.
import java.util.*; 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

I am working on a StringBuffer program and I am getting the following error message: Cannot find symbol - method append(java.lang.String) with this part of the code selected:
The problem I'm having right now is invoking the get method in my main. I get a "cannot find symbol - variable deposit" error message. I also am at a loss as to what to do for the first two classes as well as the interest class. What I had for the first two didn't work, so I scrapped itand don't remember what it was.
Here's the code and error message:
import java.text.NumberFormat; import java.util.Scanner; public class BankAccount { private double balance; private double name; private int BankAccount;
