Unreachable Statement Error
Jun 11, 2014
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.
/* 12992: */ private int extractInterfaceValues(RSInterface class9, int j)
/* 12993: */ {
/* 12994:11712 */ if ((class9.valueIndexArray == null) || (j >= class9.valueIndexArray.length)) {
/* 12995:11713 */ return -2;
/* 12996: */ }
/* 12997: */ try
/* 12998: */ {
/* 12999:11716 */ int[] ai = class9.valueIndexArray[j];
/* 13000:11717 */ int k = 0;

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.

public String toString()
{
return questionText + "
";
char label = 'a';
for(int i= 0; i < answers.length; i++)
{
return "("+label+")"+" "+answers[i]+ "
";
label++;
}
}
I keep receiving the unreachable statement for line 4. I don't know why?

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.
import jsjf.exceptions.*;//Error on jsjf

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...

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.
public String checkPasswordStrength(String passw) {
int strengthCount=0;
String strengthWord = "";
String[] partialRegexChecks = { ".*[a-z]+.*", // lower
".*[A-Z]+.*", // upper
".*[d]+.*", // digits
".*[@#$%!]+.*" // symbols

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;

private String name;
private MyDate birthday;
public Person(String name, int pp, int kk, int vv) {

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

i'm confused about the if statement part because int i = 0 is set to zero but how can you get the remainder if int i is zero?
for (int i = 0; i < 200; i++) {
if (i % 12 == 0) {
System.out.println("#: " + i);
}
explain to why it output like this?
#: 0
#: 12
#: 24
#: 36
#: 48
#: 60
#: 72
#: 84
#: 96
#: 108
#: 120
#: 132
#: 144
#: 156
#: 168
#: 180

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)
[code]...
