I have generated wsdl2java code using axis 1.4 . One classes has 2 constructor methods (one default constructor and other one has 2 parameters). Other classes that inherit from one class have the constructor parameters in the wrong order. The schema files is correct as they come from the OTA specification. What should be done to get rid of this ordering problem in constructor

Explain how to catch block act as constructor with parameter?
How to use a constructor with parameters where the user inputs the information? I'm doing a problem where I create a Delivery class that accepts arguments for the year, delivery number within the year, distance code (1 for short distance, 2 for long), and weight of package. The constructor is supposed to also determine the eight digit delivery number (combining the year and delivery number, like 20140054 for this year, package #54).
I know I'm not close to being done but I'm struck on the application with the constructor parameters. If I'm asking the user to input the information, does that mean I have to create a no argument constructor so it will compile? Right now it won't compile because it's asking for the parameters but I can't put them.
This is the class:
public class Delivery {
int year;
int delNum;
double weight;
int code;
[Code] .....
And the error is:
CreateDelivery.java:22: error: constructor Delivery in class Delivery cannot be applied to given types;
Delivery firstDelivery = new Delivery();
^
required: int,int,int,double
found: no arguments
reason: actual and formal argument lists differ in length

I want to create an order system. My Problem is that I want to create it dynamic, with ArrayLists and no fixed Array size.
Basically I have already a User which is able to purchase something.
User a = new User();
Car car = new Car("blue",500);
a.purchase(new Order(new OrderThing(5,car));
This will work!
But I want something like this:
a.purchase(new Order(new orderThing(5,car), new orderThing(2,car), new OrderThing(1,car),...)
Basically I don't know how much OrderThings I want to create before I type in the OrderThings with new Order().
But in java it is before you can construct orderThings you must already know in the constructer how much objects you do want.
Now as im writing this question I got a idea of waiting for an Array of new OrderThing but it don't work. When I write
a.purchase(new Order(new orderThing(5,car), new orderThing(2,car)))
it wants a constructor which is based on Order(orderThing,orderThing)
I have to create a constructor with eight parameters containing both string and integers.the variables were supposed to be entered by user. but when I try to create an object of the class the IDE post error messages about the constructor.

//after the main method I try creating an object of the class
//after prompting the user to enter the data
hfile hfile= new hfile(firstname, lastname, gender, age, weight, height);
}
The one problem in my book was to create a constructor for different shirt features, which I did and ran successfully. Out of curiosity, I also added other methods to see if it would run if the parameters were different from the constructor. It keeps giving me a constructor error. So, my question is, am I able to create a class that uses a constructor with parameters and other methods without errors? I'm guessing there's no reason to since it would be wasted space since the constructor could do it but was just curious if it's possible.
Is everything from the constructor down (in the class) and Shirt.oneShirt (in the main) just a waste of time?
Here's my example:
public class Shirt//class name.
{
int collarSize;//data field.
int sleeveLength;//data field.
int pocketNumber;//data field
public final static String MATERIAL = "cotton";//final data field for material.
public Shirt(int collarSize, int sleeveLength, int pocketNumber)//start of constructor.

One of the random number generators in Java extract the higher-order bits of the random number in order to get a longer period.
I'm not sure if I understand how this is done. Suppose that the random number r = 0000 1100 1000 1101. If we extract the 16 most significant bits from r; is the new number r = 0000 1100 or r = 0000 1100 0000 0000?
Any link to the accurate explanation of binary trees in java?
View Replies View RelatedSearching methods and sorting methods, I tried some (SelectionSort, InsertionSort, BubbleSort, SequentialSearch) and they all work, but I am having problems right now with my BinarySearch method. The problem(s) I have right now is that the method is only finding some numbers in my array, such as 1 and 8, but when I search for the other ones it only buffers and the program has to be stopped manually, since it doesn't print anything. I tried rearranging the while-loop's circumstances but that didn't work.
how to optimize my coding for future tasks so I dont get the same problem(s).

I have a problem with timezone in my java application. My current/correct timezone is "Europe/Berlin" or CEST. When I type the following command as my user I get the correct output back:
$ date "+%Z %z"
CEST +0200
But when I run my java application it is using the timezone GMT+0100. I have executed the following Java code to verify:
import java.util.Date;
import java.util.TimeZone;
public class TimeTest {
public static void main(String args[]) {
long time = System.currentTimeMillis();
[Code] ....
When I run it the following output is generated:
Current time in milliseconds = 1435319087443 => Fri Jun 26 12:44:47 GMT+01:00 2015
Current time zone: GMT+01:00
Fri Jun 26 12:44:47 GMT+01:00 2015
So where does java get its timezone from? It's different from the default system timezone.

There are not enough funds to do that
Balance: $0.0
Monthly Interest Rate: 0.375%

I assumed that this is because the constructor Account(); is setting the variables to 0 every time the program runs even though I'm passing other variables through to methods and constructors. I've looked up similar programs and this is how it's done though. The steps to my homework say to create a no-arg constructor Account() that creates a default(0) account Id and balance. What did I do wrong?

I've been given a school assignment that reads, "Rewrite the main class Geometry so it takes in the dimensions for the triangle and ellipse as user inputs and create a Triangle and an Ellipse class. Use the appropriate variable types, constants, variable names and computational formulas.
Triangle class will have a computePerimeter and a computeArea methods Ellipse class will have a computeArea method Create Report class
• Create a method createReport that takes the values returned from Triangle and Ellipse and combines them in the following message and displays it. Format the values so that they have 2 decimals.
“The triangle has a perimeter of [perimeter] with an area of [area] while the ellipse has an area of [area]”
• Create a method switchReport that takes the original string from createReport and changes the message to display using the available methods in the String class
“The ellipse has an area of [area] while the triangle has an area of [area] with a perimeter of [perimeter]”"
I've run into a problem when creating the createReport method. Everytime i run it i get incorrect values for the perimeter and area (namely i get zero every time).
my code is as follows:
public class Triangle
{
public double base;
public double height;
public double hypotenuse;
private double tArea;
private double perimeter;
public Triangle()
{
base = 0;
height = 0;
hypotenuse = 0;
[code]....
For the triangle class and
public class Report {
Triangle tri2 = new Triangle();
Ellipse eli2 = new Ellipse();
public Report() {
}
public void createReport() {
System.out.println("The triangle has a perimeter of "+tri2.computePerimeter() +" with an area of " +tri2.computeTArea() +" while the ellipse has an area of " +eli2.computeEArea() );
}
for the report class.the Geometry class allows you to input values and if i skip the report and simply print the perimeter and area they are correct. However with the report class it simply gives me zeros.
So the idea of this program is that you enter a number, it will give out a radius ... After the radius is given then, it will ask if you want to continue yes or no, if yes then it will repeat the process. If you select no then you will be greeted with a message saying "programme complete, See you later" ...
This all works fine and the code is below... however I want to add a pop up message if someone enters an invalid Character (anything that is not a number) ...

Write a program that prompts the user to input cash amounts and use a method to calculate the average amount for a week given 7 inputs of daily cash intake amounts for a cash register. Use an array to store the values. Recall that average is the sum of the values divided by the number of values. The method should take argument(s) of type double and return average weekly cash amount as a double.
Make sure you test your program using the test data given below and calls the averageCash() method defined above passing in the values. Verify that the input values are greater than or equal to 0. Negative numbers are not allowed. Output the values used and the averageCash value.

I have a problem with this application , I have a button that allows users to delete entry's from the array list, but i've noticed when i go back and click display entry's the correct entry has not been deleted.....for example if i enter a,1,2 then b,1,2, then c,1,2 in fields, then delete c,1,2 when i actually go to display the data entered a,1,2 will be gone not the one i entered.
So it seems to be deleting the entry at index 0 of the array list no matter what and not the chosen item..Delete Button Code

I'm using BarChart and I've a very strange problem. Is not very simple create a test case to understand where is the problem.
In the first image is displayed a bar with the value of 2 but as you can see the y axis is not correct.
In the second image the value displayed is 4 but the y axis is completely busted.
Important thing: In my real app I change data of the chart every time the user change a combobox value (the period).

I am trying to connect to Sql Server database using Oracle UCP with sqljdbc4-3.0 JDBC driver for Sql Server,with different ports and instances.
– the issue is with the port being ignored in the server string.
For example, using port 1440 connects to the default instance (which is on port 1433) rather than MSSQLINSTANCE1 which is on 1440.
Below are Server hosts used.
sql005.sqlasoftware.com (connects correctly to the default instance)
sql005.sqlasoftware.com:1440 (connects incorrectly to the default instance on port 1433)
sql005.sqlasoftware.comMSSQLINSTANCE1 (connects correctly to the named instance)
Why is the equals-method in the super-class invoked? Shouldn't the equals-method in the sub-class be invoked(at least in the first if-statement since b2 is a B(i know B is also an A))?Is the equals-method overridden? Or does B have its own equals-method?
class SomeClass{
public static void main(String[] args) {
B b1 = new B(123,1);
B b2 = new B(123,2);

My program is reading my file, but its printing out weird cryptic numbers instead of the 1-10 that is in the file. But it uses the numbers in the file to get the Max Value and Total. Also I am receiving 0 for my Minimum Value but, 0 isn't even in the file, my lowest value is 1.

I want 1 for my Minimum and I want 5.5 for my average, when I make 'average = total / numbers.length;' ---> 'average = total / (double)numbers.length;' I get 0.55. Also, as its obvious, my 'Numbers being used' section is messed up and I don't know whats causing this.
We use a Java program to read an XML file and put its content into a database. We also use Date() to get the current date and insert it into a field in database with content from XML file. Everything worked flawlessly until today, the last day of 2013. We are getting 2014 for the year instead of 2013!!! System date shows correct year, so this must not be an issue.
