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.

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 was almost finished with my program when I noticed I had a big logical error. At the very beginning of my else if statements I would jump down to my else statement.
Java Code:
import java.util.Scanner; public class InternetServiceProviderNew { public static void main(String[] args) { double packageA, packageB, packageC, extraA, extraB, userHours, aHours, bHours, cHours, userCharges; packageA = 9.95; packageB = 13.95; packageC = 19.95; aHours = 10; bHours = 20; String userPackage, A, B, C ;
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'm getting errors on all the exceptions called EmptyCollectionException. I think this is because the import statement has a error on it but I'm not sure. I'm suppose to add methods for peek, isEmpty, size, and toString methods. I only started isEmpty also am wondering what I have to change from peek method if anything at all.

My if else statement is not working...it keeps telling me that the else in the statement is a syntax error and that I should remove it. Whats wrong with it?
package Homework2; import java.util.Scanner; public class Homework2 { public static void main(String[] args) { // TODO Auto-generated method stub System.out.println("Welcome to the Triangle Program.");
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 ) ;
I have a problem about this numeric or value error on my java class. Whenever I am calling for the procedure in callable statement it says that error. I don't know what is the problem with my sql code because I;ve tried running it on database alone and it runs perfectly. The results that I need came out fine. But when I'm already calling it in java that error appears. But I tried on finding the line that the said error is coming from and here is the code...
create or replace PROCEDURE RENTING (P_NNAME IN VARCHAR2, P_ADD IN VARCHAR2, P_PHONE IN NUMBER,
I've created a constructor in bean and put an value to my string after doing so all started to work properly. I am trying to get my application to work but no luck so far. I have looked for similar issues but although there were similar I've got no luck in fixing mine.
When I am trying to put an value in the input file i got error message (/zadanie_1.xhtml @15,75 value="#{z_1.lancuch}": Target Unreachable, identifier 'z_1' resolved to null).

So from what iv learnt in Java and programming in general is that using a case statement is far more efficient that using multiple IF statements. I have an multiple IF statements contained within a method of my program, and would like to instead use a case statement.
So I want to make a simple Java that ask the user to pick a powers and it has two options.If the user picks magic then execute the first if statement then ask the user again which type of magic the user wants.I can't make it work it keeps printing the else statement. Why is that?
import java.util.Scanner; public class Variable { static Scanner zcan = new Scanner(System.in); public static void main(String[] args)
I'm trying to run an if statement with an input condition and here is my code.
import java.util.Scanner; public class App10A { public static void main(String[] args) { Scanner fun = new Scanner(System.in); System.out.println("What's your name?"); String name = fun.nextLine();
[code]....
When the computer asked me "What's your name?", I typed in Victor, then the result turned out to be "Oops, try again!".I typed in Victor (without parenthesis) and "Victor" and both gave me the negative results.What exactly should I put in in order to get "This is the result I wanted!" ? how should I modify my code in order to get "This is the result I wanted!" when I put in Victor (without changing the equal sign)?
How do I use a variable in an if statement to return a public void method from another class? I've tried:
System.out.print("select 1 - 6: "); Scanner myScanner = new Scanner(System.in); myScanner.nextInt(); if (myScanner.nextInt()==1) { carSelection colour = new carSelection(); colour.carSelection();
The method colour in class car selection is just 4 print line statements? I've // out the if statement to see if it is correctly calling the method and displaying the data and it is?
I'm having a problem where an if statement isn't working. In the Person class boolean olderThan ignores my if statement so it always returns false and I just don't get why that's happening.
import java.util.Calendar; public class Person { private String name; private MyDate birthday; public Person(String name, int pp, int kk, int vv) { this.name = name;
In the program below I populated three arrays: student id, name, and GPA. The findStudent() method attempts to match users input with the input stored in the studentID array using an if/ else statement. When I use the if/ else statement the else always executes regardless if the IDs match? I am trying to get JOptionPane.showMessageDialog(null, "Incorrect entry"); to print only if the IDs don't match.
Java Code:
//FILE: StudentIDArray.java import javax.swing.*; //Used for the JOption dialog boxes import java.util.*; //Used for Scanner input public class StudentIDArray { boolean nameFound = true; final int numOfElements = 2; //Final int to control to loop for data
My program basically has 2 executeQuery statements. Based on the result of the first sql query the 2nd sql query gets executed (I intend to use if else ladder). The control executes the first query but never executes the second one.
I have this JAVA written but I can't get the parameters for the if statements right.
import java.util.Scanner; public class myFirstJAVA { public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.println("Please enter command: "); String text = input.nextLine();
I am making a simple calculator. I want the user to input either string "add" or "subtract" and then it will take two numbers and either add or subtract them. I cannot get the if statement to work with a string!
import java.util.Scanner; public class newcalc { public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.println("Enter add or subtract");
I'm trying to make a test on java. So far I'm on Question 1 and I'm having this issue. The if else statement won't allow me to add to the score.
class ExamEngine { static CinReader Cin= new CinReader(); static int Score=0; public static void main(String[] args) { System.out.println("Type in your name."); String name=Cin.readString();
[Code] ....
If I remove the "Score++;" bit, everything is fine. But I need to add to the score when they answer a question right. However, with "Score++;" there, I get this issue: 'else' without 'if'.
Note that this cannot be multiple choice, so that's why I'm using if-else, because I don't think a case system would work here.
Is there a way I can make this work while adding to the score?
I've done a basic login GUI for a application, a user enters their name and address and clicks register, a four digit pin is then randomly generated, the pin and name and address are all added to an object of the MemberDetails class , this obj is then added to an array list.
returning customers can then enter a previously generated pin and either get a welcome back message or an invalid pin message.
my issue if i register two new users and get their generated pins, that on the returning members screen it will only show the welcome message for the second new customer i created and not recognizing the first customers pin. heres my code:
taking in new customer details, generating pin , adding obj to arraylist
int randomPIN = (int) (Math.random() * 9000) + 1000; members = new MemberDetails(); members.name = nameNew.getText(); members.address = addressNew.getText(); members.pin = randomPIN;
[Code] ....
that lest method is a bit of a mess i know, i was going to store the log in attempts in a array but thats probly not a good tactic, and that inner for loop is probly unnecessary ?
I have two different Class object arrays storing 3 elements (2 Store arrays, both initialised to hold 3 Product objects). The problem is, I can set data to one array with no problem but my program doesn't want to set the data for my second array.
For instance, The main problem is this method:
public void addData(String store, String newName, int newDemand, double newSetup, double newUnit, double newInventory, double newPrice) //Method that sets the data value for a product { if (store.equalsIgnoreCase("callaghan"))//!!!!Goes from this line in the debugger if (noOfProductsCallaghan==0) { setData(product[0], newName, newDemand, newSetup, newUnit, newInventory, newPrice); noOfProductsCallaghan++; } else if (noOfProductsCallaghan==1)
