I am just learning java now i have a problem where i have to run a test order on my internalOrder class from the orderTester class and i,m not sure how to do this ?
This is the code i have for my order class:
public static void testCase8(){
orders ords = new orders ("Pen", 8, -0.5);
System.out.println("Test Case 8:" + "
" + ords.getOrderDetails());
[Code] ....
This is the code for my Internal class
public final static double DISCOUNT = 0.4;
public InternalOrder(String productName,int quantity ){
super(productName, quantity,DISCOUNT);
}
public void printInternalReport(){
System.out.println("Printing internal report ...");
}
Now my orderTest class is passed though orders class if you need that code i will put it up...

I'm deploying Java 8 update 40 to my users and want to know if there's a way to manage sites that prompt the user with warnings about untrusted and unsigned applets?
i'm using the exception.sites file to manage applicable prompts/warnings for our internal sites, but doesn't look like the exception list works for untrusted and unsigned.
is there a way to manage these from an all users level, particularly with a deployment (ie, SCCM)?
I am trying to create a java program to sort an array in ascending and descending order. Here is the program I created :
import java.util.Arrays; import java.util.Collections; public class ArraySort { public static void main(String [] args) { int [] num = {5,9,1,65,7,8,9}; Arrays.sort(num);
[Code]...
BUT I GET THE FOLLOWING EROOR ON COMPILATION
ArraySort.java:12: error: no suitable method found for reverseOrder(int[]) Arrays.sort(num,Collections.reverseOrder(num)); ^ method Collections.<T#1>reverseOrder(Comparator<T#1>) is not applicable
I have wrote the necessary program for the class which was : Modify the customer class to include changeStreet(), changeState(), and changeZip methods. Modify the account class to include a changeAddress() method that has street city and zip parameters. Modify the Bank application to test the changeAddress method.
The problem arose when I went to test it. For some reason when it asks "Would you like to modify your account information? (y/n)" it will not allow the user to input anything and thus test the class. Here is my code
Class Customer import java.util.*; import java.io.*; public class Customer { private String firstName, lastName, street, city,state, zip;
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?
When does an internal cast actually happen? I am aware that compound assignment operator do an internal cast. Does it happen in Assignment 1?Assignment 2?Assignment 3?Assignment 4?
Java Code:
public class Parser{ public static void main( String[] args){ byte b=1; short s=1; int i=1; s=b;//Assignment 1 s<<=b;//Assignment 2 b<<=s;//Assignment 3 s +=i;//Assignment 4 } } mh_sh_highlight_all('java');
This is what I have to do:Write a program that takes a string of someone's name and prints it out last name first. Your program must use pointers, not array subscripts. You may use the available string manipulation functions if you find an opportunity.
Example:
"George Washington" "Washington, George"
I am not sure how to reverse the name, I have been looking in my textbook and online and cannot figure it out. This is what I have put together so far, it does not run. At the end it says unnecessary return value.
import java.util.*; import java.util.Scanner; public class Test { public static void main ( String [] args ) { Scanner sc = new Scanner(System.in); System.out.print("Enter name: "); String name = sc.nextLine(); String lastname = ""; String firstname = ""; for(int i = 0; i < name.length(); i++) { if(name.charAt(i) == ' ')
My program compiles and runs ok how ever when i open my Jinternal frame and click on one of the JLabels i get a error on the Cmd ther error reads as follows
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at JLabelAssignment.mouseClicked(JLabelAssignment.jav a:429) at java.awt.Component.processMouseEvent(Component.jav a:6508) at javax.swing.JComponent.processMouseEvent(JComponen t.java:3320)
I am attempting to make a CoalescedHashMap<K, V> with internal chaining. It isn't a hard concept, but it needs to extend AbstractSet and implement Map<K, V>.
Map requires a remove method that returns a V(value). AbstractSet extends Collection, which requires a remove method that returns a boolean value. It gives a syntax error either way it is done. This is a standard homework assignment for a junior level class, so there must be some way to deal with this. It is annoying as we do not need to implement the remove method, it just throws and exception.
I'm struggling with inheritance in my assignment. The assignment states that I should use the calculatePrice() to calculate the total price and use another method to display the total. The I must overload the calculatePrice() and add a fee in the SpeedOrder() class.
My main class
package useorder; import javax.swing.*; public class UseOrder { /** * @param args the command line arguments */ public static void main(String[] args) { Order.display();
[Code] .....
The problem is mainly displaying the TotalPrice field and. I can't display TotalPrice if it's not static but if it's static I can't inherit it to the SpeedOrder class to assign the total in the overloaded calculateprice method. How can I display the total in my order class and use it in my SpeedOrder class?
I've installed the Java JDK onto my Windows 8 laptop and the first thing I need to do is run the compiler from the Command Prompt. The first prompt I enter is C:java -version. This worked fine, however when I try to enter the next prompt C:javac -version, I am getting the following screen and messages:
Microsoft Windows [Version 6.3.9600] (c) 2013 Microsoft Corporation. All rights reserved.
C:UsersMary>java -version java version "1.8.0_20"
Java(TM) SE Runtime Environment (build 1.8.0_20-b26) Java HotSpot(TM) 64-Bit Server VM (build 25.20-b23, mixed mode)
C:UsersMary>javac -version 'javac' is not recognized as an internal or external command,
operable program or batch file.
I have entered the path into the environment variables area within my control panel. Not too sure why the first prompt works, but the second doesn't...
I have a design scenario here which is quite interesting and complex. I have a Java class structure as follows,
class A { class B; innerClass B { List<class C> listofC; innerClass C { String attribute1; String attribute2; // Their getter setters } } }
So I have this as an API. Now my challenge is that I need to add one more property to inner class C. i.e attribute3 in innerClass C. I need to do this without disturbing the code in class A by extending these classes or writing a new wrapper, so I can use class C with new properties .
I hope this should be achievable through any design pattern either at runtime or design time.
I have the following double linked list and I'm supposed to order it descending (reverse) using the printInReverse() method; since the list orders itself ascending when the numbers are added, how could I order it descending in this method? Here's the code without implementing descending/reversing methods:
ABC is a company that designs and prints personal business cards. The company has asked you to write a Java application to display the layout of the information in a typical business card order. Data items in a typical business card include the customer's name, address, city, state, postcode, home phone number, and work phone number.
Write, compile, and test a Java class that displays these data items in a command window. Alternatively, you could also create it using a dialog box. Please include appropriate comments in your class.
Please named your class BusinessCard(LIM).java. (eq. BusinessCardLIM.java)
i want to write a class in such a way that i should get the current execution time of another class which is running. I searched in net but it shows only how to calculate the time duration of the current class which is running. But as per my way, i need the execution time of one class from another class. How to do this ?
I am working on a calculator for Android.To make sure the application I am developing works with multiple operations (in the correct order) I decided to use ANTLR as part of my Java coding of the calculator. So in a separate file (.g4 file), I must declare the format of the expression.
After which I need to include the ANTLR class library in my Java Class. Then I believe I need to call a set of functions such as createLexerInterpreter and createParserInterpreter, but I am not sure. I will be having an algorithm string that will need to be parsed, such as " 3+4*5+8*9+(5/6) ".
I will give an example below of what I am talking about. in C++ I know I would need a copy constructor because I would be pointing blindly in the heap if I deleted a object in the struct.
We have a Class/struct animal and three animals in that class/struct, a dog, a cat and a cow. Each animal has a baby and then I will give the animal a name in main. But if I delete one of the dogs puppies because I sold him wouldn't I being pointing off in the heap and have a leak?
Also since Java doesn't have structs can I put a class inside a class?
I have an ArrayList of employee and ArrayLsit of bosses, and I want to keep those people in a temporary ArrayList , then ordain alphabetically by name, to sort I use the interface comparator.
The problem comes when I will order 2 ArrayList(workers and bosses), because every time I call I use these functions or not is ordered (sortByNameAlphabetical())
public class Employee { private String name; public String getName() { return name; } @Override public String toString() { return name ;
