import java.util.Calendar;
import java.util.GregorianCalendar;
public class CalendarCalc {
public CalendarCalc (){}
private static void printCalendarMonthYear (int month, int year)
[Code] .....
IDE is telling me this:
Exception in thread "main" java.lang.Error: Unresolved compilation problem:
The method printCalendarMonthYear(int, int) is undefined for the type CalendarDisplay
at CalendarDisplay.main(CalendarDisplay.java:46)
Btw, I have a main class. This is just the class responsible for doing calculations.

My code runs and compiles just fine when I insert 3 values, however, if I add anymore values NOTHING happens. When I hit the compile button, my mouse pointer turns into that loading circle thing and after 3 seconds it disappears and nothing happens. No error or anything in the console, just BLANK. This problem occurs on line 12 in my main method, and my insert method is on line 41 in the third class..Here is my main method
public class TestAVLTree {
public static void main(String[] args) {
/*test at least 2 diff data types*/
//AVL of ints
AVLTree<Integer> avlInt = new AVLTree<Integer>();
avlInt.insert(100);
avlInt.insert(50);
avlInt.insert(200);
//avlInt.insert(3); fails here. could it be my insert method?
//avlInt.insert(17);

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

I'm writing basically my first program for school. I've written small ones, following instructions, but this is the most vague. I'm having issues. I can't figure out what the error means. I'm not done with the code, but I think the ArrayList is throwing me off. I'm trying to gather user input and sum the total. Here's the code:
package graduationplanner;
import java.util.ArrayList;
import java.util.Scanner;
import java.lang.Double;
public class GraduationPlanner {
public static void main(String[] args) {

I keep getting the error Admit.java:10 cannot find symbol
import java.util.*;
public class Admit {
public static void main(String[] args) {
sayIntro();
Scanner console = new Scanner(System.in);
System.out.println("Information for applicant #1:");
getScore(console);
getGPA(console);
[Code] ....
The compiler then reads:
Admit.java:10: error: cannot find symbol
score1(ACTScore, SATScore, GPAScore);
^
symbol: variable ACTScore
location: class Admit
Admit.java:10: error: cannot find symbol

i wrote this program:
class hellojava
{
public static void main(string[] args)
{
system.out.println("hello java");
}
}
Then i saved this file with name hellojava.java(notepad) in C drive in separate folder c:myjavaapp(not in c:java folder).
When I am compiling(with javac hellojava.java) it shows following error:
cannot find symbol public static void main(string[] args), and also says package system doesnot exists system.out.println("hello java");

I have a msg object that contains an ArrayList<Integer> collection. However, in order to send the elements in the array over the udp socket, it needs to be sent as a byte[] array. So why am I using ArrayList<Integer> over byte array in first place? Well when I receive data from socket from embedded c program, I need to get an unsigned representation of the data, and thus I need to store it in integers, since bytes in Java are unsigned and unsigned chars in c that are greater than 127 will yield incorrect values in java. But when I send an ack back over the socket, I need to send the data back as bytes. So I convert the ArrayList<Integer> to a byte array:
Java Code: byte[] data = msg.toByteArray();
DatagramPacket response = new DatagramPacket(data, data.length,
packet.getAddress(), packet.getPort());
public class Gprs {
...
public byte[] toByteArray(){
[Code] ....
The problem is I get an "Cannot cast from Integer to byte" when trying to cast the integer to byte: data[i] = (byte)m_data.get(i);
How can I resolve this?

Following is the warning on using readLine().
The method readLine from the type DataInputStream is Deprecated.
An additional line suggestion is added by eclipse and that is
@SupressWarnings("deprecation") ;
Can delineate this?

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:

This method accepts 1 integer, amount (the amount of money). Output the minimum number of in quarters, dimes, nickels and pennies used to make up the amount. For example, an amount of 32 would require 1 quarter, 1 nickel and 2 pennies.
This is the question^
My codes are:
public static int change (int amount) {
int quarters = amount / 25 ;
int firstresult = amount % 25 ;
return quarters ;
int nickel = firstresult / 5 ;
[Code] .....
The codes were working when i used System.out.println instead of return, but our teacher required us to use return (functions).
I get the compile error: Unreachable statement.

import java.util.Scanner;
public class GradingApplication {
public static double score(double score){
if(score >= 90){
System.out.println("A");
[code]...
~Problems~
1. It has no gui, I don't know java fx, is java groove used? awt is useful for creating spam bots in robot class, I know it's not very useful but it's so much fun.

class SubB{
public void foo(){
System.out.println(" x");
}
}
public class X extends SubB {
public void foo() throws RuntimeException{
super.foo();
if(true) throw new RuntimeException();
System.out.println(" B");
}
public static void main(String [] args){
new X().foo();
}
}
Why the foo method of class X is not throwing a compile error because according to the override rule, if the superclass method has not declared exception, the subclass method can't declare a new exception...

I have a code in which I am reading input from System.in and Destination is some where else
Here is my code
File file=new File("D:/output.txt");
OutputStream os=new java.io.FileOutputStream(file);
Scanner scanner=new Scanner(System.in);
System.out.println("Enter Data to write on File");
String text=scanner.nextLine();
int c=Integer.parseInt(text);
int a;
while((a=c.read())!=-1)
os.write(a);
System.out.println("File Written is Successful");
In the line while((a=c.read())!=-1)
a compile time error is shown "cannot invoke read on primitive data type int"

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();

the system I am using is blue jay and java. my problem is that I have this error message pop up whenever I try to compile any of my 6 classes. Three of the classes are cities, 3 others are shops, and the final one is a inventory called Player. The following is the error code that appears when I try to compile class THshopB or class CityB.
method run in class CityB cannot be applied to given types;required: Player; found: no arguments; reason: actual and formal argument lists differ in length
A similar error occurs for the rest of my City and THshop classes,except it replaces the class CityB with CityA and occurs in class THshopA, replaces CityB with CityC when occurring in class THshopC.The public methods of CityB and THshopB are shown below, as I believe that something is wrong with the public method of one or the other. I have the code [CItyB.run();}] inside of class THshopB, and run is the part that gets the red highlight error described above.THshopB public method
[ public static void shop(Player inventory){
CityB.run();}]
CityB public method
[ public static void run(Player inventory){
THshopB.shop(inventory);]
All of my THshop classes are written in the same format, and all of my City classes are written in the same format,

There are 2 methods and a main one. The first is a void that creates a 3x4 2d array and the second is to search for a value in the array, if found it will return the number of the row that contains that value. If not, it will return -1, but I am getting 1 error and 1 dead code warning.I will put comments at the lines that contain the problems
import java.util.Scanner;
class Question4{
public static void main(String[]args){
Scanner s = new Scanner(System.in);
int x,n;
System.out.println("Please input the value that will be used in the array");
x=s.nextInt();
System.out.println("What is the value you want to search for?");
n=s.nextInt();
createArray (x,n);
