I am suddenly facing error messages when launching my eclipse. Below are the eclipse logs:

I have tried downloading and placing org.eclipse.swt-3.1.jar in the plugins folder of my eclipse and also I tried editing eclipse.ini file with below lines
openFile
-vm
C:Program Files (x86)Javajre1.8.0_25injavaw.exe
-vmargs
but nothing worked.
I'm currently new to java and I would just like to ask if Socket is sufficient for this file transfer app I'm planning to work on.
The specs are as follows:
~ Move/Copy Files of selected folder/s to a single folder(consolidating them) within the same machine and Network
~ File type will be specified on GUI and those specified will be the ones transferred
~ option to choose Move or Copy of files
~ ability to create/select folder of transfer destination
Here is an draft of what the GUI will look like.
I am doing a pretty basic program with a fixed origin city and five destination cities. I am having trouble with entering passenger details. This is what I tried, but then I cannot retain all passenger details to print later on in the final ticket.
System.out.println("Enter flight details of child passengers (below 12 years)");
System.out.println("Enter Name");
for(a = 1; a <= cp; ++a)
{
//cp is number of child passengers, a is loop variable
String name = br.readLine();
System.out.println("1. " + name);
}
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.
Whenever i try to compile the code, I get " cannot find symbol".
Java Code: public class NinePointOne{
public static void main(String[] args){
Rectangle rec1 = new Rectangle();
}
} mh_sh_highlight_all('java');
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:
import java.util.*;
import java.io.*;
import java.util.Scanner;
public class Program7{
public static void main(String args[]){
Student student = new Student();
[Code] .....
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'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
[Code].....
See code.
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") ;
[Code] ....
When I compile getting
CQ1v1.java:12: error: cannot find symbol
x = in.nextLine ();
^
symbol: variable x
location: class CQ1v1
CQ1v1.java:21: error: cannot find symbol

This is my Error:
MergeList.java:55: cannot find symbol
symbol : variable Arrays
location: class MergeList
System.out.println(Arrays.toString(merge));
^
This is my code:
public static void main(String[] args) {
int[] first = { 1, 4, 9, 16 };
int[] second = { 9, 7, 4, 9, 11 };
int[] merge = new int[first.length + second.length];
int j = 0, k = 0, l = 0;
int max = Math.max(first.length, second.length);

In my project..while running a main program "cannot find symbol" error occurred.. I've attached error page,char1.java and BarRenderer.java files...

I made a breakout like game that runs as a applet and now i wanted to make it run in a jframe so i wrote this
Java Code:
import java.applet.*;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.awt.image.*;
public class BrickBuster{
public static void main(String[] args){
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
JApplet BrickBuster = new JApplet();
frame.add(BrickBuster);
BrickBuster.init();
}
} mh_sh_highlight_all('java');
It compiles fine but whenever i try running it with the java command it says it couldnt find or load main class. also i have it save in a folder called BrickBuster so i called java BrickBusterBrickBuster.class
I tried running this program but shows some compilation error of cannot find symbol . in following:
p1.num, p2.num and p3.num
cass Guessgames
{
void startgame()
{
Players P1=new Players();
Players P2=new Players();
Players P3=new Players();
boolean p1isright=false;
boolean p2isright=false;
boolean p3isright=false;
int guessp1=0;

why I am getting an error at Line 1 - cannot find symbol:
public void timesTwo()
{
String numberString;
int number, answer;
boolean again = true;
[code]....
I'm not sure if I am doing something wrong or what but I can not get this to run
it gives me an error on lines everytime there is an object ch as line 3. with error "cannot find symbol"
public class EmployeeDemo {
public static void main(String[] args) {
Employee e1 = new Employee();
e1.name = "John";
e1.ssn = "555-12-345";

I am trying to run the following code but getting the error above.
import java.io.*;
public class StringBuilder {
public StringBuilder() {
super();
}
public static void main(String args[]) {
// creates empty builder, capacity 16
StringBuilder sb = new StringBuilder();
// adds 9 character string at beginning
sb.append("Greetings");
}
}
I am writing a palindrome program. I don't understand what is wrong with my Main method. It is giving me error and error is "Can not find symbol in main method"

I have a problem that happens randomly where i try to compile and it just comes up with error
"Error: Could not find or load main class com.productiontrackingscreens.rexam.EmployeeAddressList"
This is a program that worked fine until i started it today. Seems a bug with eclipse.
I'm trying to run a java program from cmd. I'm using Windows 8, java version "1.8_0_20". I've got two classes, the main class called Middleware and a secondary class, called WorkerThread, of which the main class is using functions. I've successfully compiled both .java files with javac, and created the .class file. So all files are in the same folder. However, when I attempt to run the main class with java Middleware, I get the error message: "Error: Could not find or load main class". Here's the main class:
package middleware;
import java.net.*;
import java.util.concurrent.*;
public class Middleware {
//Number of threads serving clients.
private static int nr_threads = 5;
private static int portNr = 6789;
private static ServerSocket welcomeSocket;
private static ExecutorService executor;

My code compiles and runs fine in eclipse but on the console, I'm having troubles.
I am trying to create this program I am pretty sure it is easy but I am making it difficult lol, it keeps giving me a error, it is saying cannot find symbol - variable keyboard, I don't think I have keyboard as a variable but I may be wrong.
double distancel = keyboard.nextdouble(); that is the specific line ....
import javax.swing.JOptionPane;
import java.io.File;
import java.util.Scanner;
//import java.util.totalInches;
//instance variables
public class Map{

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:
import javax.swing.*;
public class CreateAliens
{
public static void main (String[] args)
{
Martian aMartian = new Martian();
Jupiterian aJupiterian = new Jupiterian();

I get an error "ArrayIndexOutOfBounds" in my Junit test on the following method:
public String[] getMACs(String ssid) {
int first = bs.searchFirst(arrayWlanMac, new GetSet(null, ssid, 0, 0),
new ComparatorSSID());
int last = bs.searchLast(arrayWlanSsid, new GetSet(null, ssid, 0, 0),

The error occurs in the first while loop right in the if condition (if (!arrayWlanSsid[i + 1].getMac().equalsIgnoreCase(arrayWlanSsid[i].getMac())) )
I'm getting an error trying to run a welcome app from a book. I've looked at the FAQs and can't seem to solve the issue. I'm guessing my path and/or classpath are not right. Here's my path environment variable.
