How to implement your own class.......I don't have a clue, please help!

I'm new with Java and am so confused! I need help with the following exercise.
Implement a class Employee. An employee has a name (a string) and a salary (a double). Write a default constructor, a constructor with two parameters (name and salary), and methods to return the name and salary. Write a program that tests your class. How do I do this?
I can't figure out how to do this!!!!! Please show me an example!

public class Employee {
  private String name;
  private double salary;
  public static void main(String[] args) {
    Employee employee = new Employee("Max Just", 64000);
    System.out.println(employee.getName() + "\nsalary: " + employee.getSalary());
  public Employee() {
    name = null;
    salary = null;
  public Employee(String name, double salary) {
    this.name = name;
    this.salary = salary;
  public String getName() {
    return name;
  public double getSalary {
    return salary;

  • Interfaces for your own classes - do you bother?

    Hi All,
    before anyone gets upset, I did post a shorter version this to the Java Prog forum a couple of days ago. I'm reposting here because the thread was pushed down the list just as comments were getting interesting, and I was tossing up which forum was most appropriate anyway...
    OK, I'd like to pose a general question on the use of interfaces with your own classes. I am totally behind the concept of using appropriate interfaces for declaration of vars, parameters etc (i.e. use "List" rather than "Vector"), but what about your own classes?
    If I have a class in my application that doesn't fit into any kind of framework or class hierarchy, subclass of object basically, should I write an interface with all the same method sigs and use that rather than the class for my vars, params etc? This would make things more flexible in future, enabling you to swap classes in and out of your app more easily.
    Taking it a step further, how's this for a design methodology: For every class you write (once again classes that don't fit into your own or somebody else�s hierarchy or framework) do the following
    1. Create an interface (MyInterface) that maps 1 to 1 to that class (MyClass), with all the same method sigs.
    2. Make the constructor private and manage all the creation of instances of MyClass through a factory that returns objects of type MyInterface.
    If you do this there will be no mention of any of your concrete classes anywhere in your app except the factories, making it easier to refactor etc. Do this for all your classes.
    A little sketchy but I hope you get idea. Is this complete overkill? Is there a down side to this? Does anyone do anything like this?
    Cheers
    Matt

    Although the pattern you describes adds flexibility, it also adds complexety.
    Imagine somebody is looking at your code and from what he sees he deducts that the next thing to look at is the concrete class which is used at a given place.
    If you used an interface, he must find out which implementing class is actually used at this place. It's not a big thing, but if every single class has its seperate interface and factory I would consider it overkill ... after all you have to write all the boring code for this.
    In the case of doubt I'd agree it's better to throw in an interface and a factory instead of refactoring thousand lines of codes afterwards. But if nothing hints toward a second implementation of the interface, or another reason for using an interface don't bother to write one.
    As a general rule I use something like: Don't use a general rule. ;-)

    tell me my friend .. how can i extend
    the standard Forms button in Java ? ... what is the tool for that ... can you explain more please .. or can you give me a full example ... i don't have any expereience on that .. i'm waiting for your reply .
    Thanx a lot for your cooperation .

    <BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by [email protected]:
    Henrik, the Java importer lets you call Java classes on the app server side - I think what Ali is trying to do is integrate on the client side.
    If you want to add your own button then if you extend the standard Forms button in Java and then use this class name in the implementation class property then the Java for your button will be used instead of the standard Forms button. And since it has extended the basic Forms button it has all the standard button functionality.
    There is a white paper on OTN about this and we have created a new white paper which will be out in a couple of months (I think).

  • How To Use Your Own Router with Out Loosing Verizon's FIOS Services

    How to use your own router with Verizon’s FIOS Service
    First, you need a basic understanding of how FIOS works but unfortunately there are two types of FIOS systems out there. All of the systems utilize a fiber optic cable to bring TV, phone and internet to your location over one optic cable. In addition these systems provide interactivity including widgets, remote DVR, movies on demand and so forth via an IP (Internet Protocol) signal.  Your STB (Set Tip Box) requires both a video and IP signal. The IP signal is necessary for all of the aforementioned interactivity.  The fiber cable terminates at the Optical Network Terminal or ONT for short.  The ONT converts the optics into a digital signal that can be utilized by ones equipment.  From the ONT your video, phone and internet are provided to the location.  This is where things can differ as the internet signal can be provided via a coaxial (MoCA or Multimedia over Coax Alliance) or RJ45 Cat5 (Ethernet) cable.  It is important to identify and understand the differences of these two setups.  In my case I have my internet entering via Ethernet cable, which in my humble opinion makes things a heck of a lot easier.
    How does one tell the difference? In most cases it’s rather simple; just look at the Verizon’s router WAN (Wide Area Network) Port.  Does it have a RJ45 (Ethernet) or Coax (TV cable Cord) going to it? If the router’s WAN port doesn’t have a coaxial connector then one will need to convert the MoCA signal into a usable Ethernet signal that routers understand. The easiest way is to use Verizon’s router as a bridge. In this method the Verizon’s router simply converts the signal and passes it along to your own router. The challenge is to try to maintain the interactivity that FIOS TV provides. Because of this one needs to supply the IP routed signal back to the FIOS router.  There are multiple methods for doing this and I would recommend investigates which one make the most sense.   
    In my particular case the IP signal was provided by Ethernet.  Again there are various ways of installing one’s own router. The hardest is to utilize Verizon’s router as a bridge.  This setup requires configuring Verizon’s router as a bridge and also creating a VLAN (Virtual Local Area Networks). In addition one needs to set up their own router so it will work with the various routing tables and networks. For me this is too complex for the average person and it can be difficult to trouble shoot if something goes wrong. Please consider that Verizon will not support utilizing third party routers.   
    The easier method is to request an Ethernet signal (if you don’t already have one) from their ONT.  I would highly recommend getting your hands on a NIM or Network Interface Module. This device is used to convert Ethernet to Coaxial so it can be fed back to your STBs.  These can be purchased online and Verizon technicians can be a valuable resource with these sorts of acquisition.  At the very least they can point you to the right direction.  Once you have a NIM the rest is rather simple.
    Log into the current Verizon Router.
    Located the router’s MAC address and copy it down.
    Go to the port forwarding section and copy down the Applied Rules. 
    Example:  
    Network Computer/Device: 192.168.1.100:63145
    Application & Ports Forward:  Application UDP Any -> 6347  
    Note: There may be up to three entries for each one of your Set Top Boxes.
    Look at your current device list, typically found on the home screen. Copy down your STB MAC and IP address.
    Example:
    IP-STB1
    Connection Type: Ethernet
    * IP Address: 192.168.1.100
    IP Address Allocation: DHCP
    *MAC Address:                07:73:fFe:ad:8b:3f
    * Things you will need to write down
    Go to the network section and look for the main Ethernet connection.  Select this and then select more setting, typically found at the bottom. Release the current lease.
    Remove the Verizon router
    Install your router
    Connect the NIM by plugging in an Ethernet from one of the routers LAN (Local Area Network) ports to your NIM. Then connect the coax cable, the same cable that was used by Verizon router.
    Set you DHCP routing IP pool to accommodate Verizon’s STB IP’s  (note their IP’s start at 192.168.1.100)
    Go to DHCP section and reserve the STB IP’s by inserting the IP’s and MAC addresses. This shall ensure that nothing else utilizes the same IPs as the STBs thereby preventing IP address conflict.  
    Add the port forwards from Step 5 above.
    Clone Verizon’s Mac Address utilizing the info from step 2
    Finish setting up the router in typical fashion.
    Unplug and re-plugin your STB’s and test functionality.  It’s best to try using a widget or Movie on demand function.
    Note: if the new router can net get an internet signal contact Verizon’s support and have them release the IP and reset the ONT.  
    EVERYTHING should be working at this point.

     3 Go to the port forwarding section and copy down the Applied Rules. 
    Example:  
    Network Computer/Device: 192.168.1.100:63145
    Application & Ports Forward:  Application UDP Any -> 6347  
    Note: There may be up to three entries for each one of your Set Top Boxes.G
    Your display obviously is not like mine as mine does not dosplay the port associated with the ip address
    whatever, the STB's start at 192.168.1.100 and icement by 1 for each
    the port addr's will be 63145 alo incrementing by 1
    there is 1 entry for each in my pf list
    however each ip addr also has a port entry starting at 35000 also incrementing by 1 for each ip addr
    For some unknow reason these are duplicated e.g I appear to have 11 entries exaactly the same for each stb and as the fios services rules have no action switc there is nowhere to delete the extraneous garbage.
    Why do you clone the mac addr??

  • I need to erase the contents of my phone and restore to factory settings. Does anybody know how to save your texts so you don't lose them?  Can I back those up to iCloud?  My phone was very likely hacked (Apple's advice was to call the police!)

    "I need to erase the contents of my phone and restore to factory settings. Does anybody know how to save your texts so you don't lose them?  Can I back those up to iCloud?  My phone was very likely hacked (Apple's advice was to call the police!)"
    That was all I could put in the initial "box."  Then it brought me to this page with instructions on how to write a good sentence.
    Proceeding ...
    After going back and forth between Apple, AT&T and the police (all telling me to go to the other two) I took AT&Ts suggestion and got a new number. One tech warned against doing a backup, especially on my Mac, saying if my phone had been hacked then whatever bug was there would then invade my computer. But nobody knows how to determine if the phone has been hacked or a virus was planted there. Unfortunately I know who would have reason to do such a thing and all I can say is that he is at the top technologically and could easily do it. Almost impossible to prove, however.
    So I need to preserve my text messages and my emails as well. I backed up my photos to that Microsoft product (One-Drive) and it froze (Surprise, Surprise) with four short videos to go, and no way of stopping that (when I tried it crashed repeatedly) so I'm in crisis mode here.
    Help ...
    Running 8.0 on 5S
    Thanks!

    Betty I don't know if you fixed your hacking problem but I feel your pain. I've seen some strange things going on between my iMac and my iPhone and Apple has told me the same thing, call the police which I have done. The hackers have stole 500.00 out of my checking account have access to every internet account I use and no matter how often I change the password their right back on the account. I closed my FB account 3 times only to have someone reopen it. Right now I've got a link in my reading list (Safari) that if I click on it, it allows me to log onto my FB account anonymously.
    I've seen a green folder come out of no where while I was trying to delete my passwords out of keychain when that green folder was put into the key chain I was immediately locked out. I than went into system preferences to try to make changes to my security settings, when I clicked on the icon it wouldn't open. I've seen log files of automator receiving commands and sending out my personal information thats on my computer.
    I have a legitamate program called iExplorer that allows you to look at the contents of your iPhone back ups and saw a transaction someone made at the Apple store for some full length movies, some albums, ibooks and other apps but when I called the iTunes store and they said none of those items were showing up on my account. If their not on my account how can they be on my iPhone 6? One day someone was using my gmail account and unknowingly used google maps to search for an Italian restaurant, than a Mexican restaurant than a coffee shop and their search showed up on my iPhone but I didn't have my gmail account installed on my iPhone 6. Using my computer I logged onto my gmail account and looked at the maps history and sure enough there were the searches when I'd hover my curser over the link it gave me the longitude and latitude of the where the hacker was when he was using google maps. I know whoever reads this thinks Im crazy but I've documented everything and can prove the things that I have mentioned in this post actually happened.
    One day I had my laptop (pc) and my iMac next to each other as I was using both. when I clicked on airport it showed that my laptop and my iMac had made a connection and were actually communicating with each other. I know I didn't do it I don't know how. The iMac was logged into my iCloud account while my laptop wasn't. I have formatted my iPhone at least a dozen times, Apple and an Apple retailer have formatted my hard drive not to mention the numerous times I have formatted it but the hackers keep getting on my devices. Im formatting my lap top at this very second because during the course of the night I left the ethernet cable plugged into it and they locked me out of my c: drive, and configured the system so I can't download any updates from Microsoft, overtime I type in www.microsoft.com it changes to ww38.microsoft.com which takes me to a blank page. I right clicked on the page I was redirected to and read the java script and couldn't believe that someone had actually configured Internet Explorer to redirect me to a blank page when I tried to go to Microsoft. Apples answer to all this is there was nothing wrong with my iPhone or my iMac and if I thought there was a problem to call the police which I have done.
    Theres no doubt the hackers are reading this while I type it or will read it and I simply don't care anymore. I no longer email anyone, don't use my iCloud account and have taken precautions to protect my credit but if I ever find out who has invaded my privacy to this extreme the police are going to want to talk to me because Im going to hurt them like they've never been hurt before

  • I get an error message when trying to install windows 7 on my macbook pro. The message says "windows has encountered a problem communicating with a device connected to your computer. I don't have anything connected to my computer. How do I fix this?

    I'm trying to install windows 7 on my macbook pro. I went through the process of bootcamp telling it to install windows 7. Once the windows boot manager started an error message came up. The error message says " windows has encountered a problem communicating with a device connected to your computer. I don't have a usb connected to my computer. I  am using windows 7 professional install disc. I  can't figure out what i am doing wrong. The same message keeps coming up over and over. Am I doing something wrong or is it something else?

    Well, shucks, i just spent almost 30 minutes trying to find your model user guide to explain it better, I guess they never got around to making it.....
    I would just borrow another Windows disk and try installing it again and if it does it again then you might take it to an Apple Store and see if one of the "Genius' " can figure it out.
    Make sure your internet is enabled and click on your blank desktop and at the top of your screen is a Help menu option, enter PRAM and it should give you a list of things relating to Pram. It may take a few seconds to list anything as it has to connect to Apples severs first. It should list the things you may have to fill back in when your done.
    "P-ram" stores some common information that is used in the background, your date, time, startup disk, etc, that you don't have to re-fill when you restart, it's a little different for each computer.

    Hi,
    Some "movies' are actually Flash files.
    This means the Flash App will play them (possibly in a browser in some cases).
    Depending where this item is and how it is playing it may be effected by other things
    A web page can include javascript.
    Apple uses javascript here to help with creating the posting box, the Edit options, Adding pics/smilies and the like.
    Sometimes the javascript can be what is called a runaway process and gets sort of stuck in an endless loop.
    If it is a free standing item then it might be triggered by AppleScript on the Mac. (or be modified in some way)
    Again if the Script (normally written with a upper case S) is not perfect it can cause problems.

    If you have Find My iPhone enabled, you can use Remote Wipe to erase the contents of your device. If you have been using iCloud to back up, you may be able to restore the most recent backup to reset the passcode after the device has been erased.
    You need the iPod and iPad conencted to the interned and FindMyiPod turned on on the iPod an the iPad need to have the FindMyiPhone app installed. That now requires iOS 7 on the device.
