Amount Of Money - Compile Error / Unreachable Statement
Feb 14, 2014
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.

I cannot see why I am getting an 'Unreachable statement' error on 'return -1;' on line 13126.I am also getting a 'missing return statement' error on the very last line.

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) {

Scanner console = new Scanner(System.in);
System.out.println("Information for applicant #1:");
getScore(console);

The compiler then reads:

symbol: variable ACTScore

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?

Netbeans do not detect any syntax errors, but I when I check the build it retuned areas they were a few; It's a simple program name 5 people, gade them then do final calulatoins it's called "grade tool.
heres the code

import java.util.Scanner;
public class GradingApplication {
public static double score(double score){
if(score >= 90){
System.out.println("A");

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.

super.foo();
if(true) throw new RuntimeException();

public static void main(String [] args){

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();

This is what i have so far, I use BlueJay to write this:
import javax.swing.JOptionPane;
public class payroll
{
String again = y;
//
private String name;
private double rate;
private double hours;
static double gross; //gross pay
[code]....
my first problem is that it expects a ")" on this line :"if ((hours <=40)rate *1);"For the assignment itself these are the requirements:
-Create a class called payroll with private variables for rate hours and name
-Create static variables for gross pay, union dues, health coverage (hp in my case), FICA taxes, State taxes, Federal taxes, net pay, all must be initialized to 0
-default constructor that assigns default values
a function called calcPay that will do the following tasks and print it to a pay stub :
- function that checks the hours ( if hours are 40 or less pay rate, if over 40 pay 150% of the rate)
- calculates gross pay before any deductions (using user inputted hours and rate)
- deduct medical coverage and union dues from gross pay and call this adjusted gross pay (also this should have its own line on the paystub)
- A function that deducts State, federal and fica taxes from adjusted gross
- FICA - 7% for any income
-Federal - 2% for $0-$150 / 6% for 150.01 - 300 / 14% for 300.01 - 600 / 18% for 600.01 - unlimited
-State - 1% for 0-150/ 3% 150.01 - 300 / 5% 300.01 - 600/ 8% 600.01 - unlimited
- amount after all deductions is the net pay ( show this amount on its own line)
- Start a loop that asks each time if there are more employees (y/n) y should continue the program and n should end it
-dialog boxes should be created to recieve values for name, hours and rate
- if the rate is entered below $8 dollars a new box should pop up and ask for a higher value
- When there are no more employees, print out a summary of quantities stored in static variable (also had a problem with this)
- End
So I think i completed most of these objectives but am having trouble with the syntax and some of the objectives

I am Having trouble with my program to validate. It is outputting null into the validation statement then it brings back a run-time error to that validation Statement for the String.
public String validateData ()
{
if (nm == null)nm = "Error! Must enter at least one character";
else nm = name;
return name;
}//end validation method
Why is this happening, and then once that is completed, why is the validation Sentence in tests Scores not able to validate. I traced it back to out put "Error, a number between 1<100".
public void validateTests ()
{
String testschange;
if (test1 < 0 || test1 > 100) {
testschange = " You have entered an invalid number, between 1-100. Please restart!";
testschange = Integer.toString( test1 ) ;
