Counting Words Contained In Address
Sep 19, 2014
I need to make this program work. It is supposed to count the words contained in the Gettysburg address. I went wrong somewhere but don't know where.
import java.util.Scanner;
public class gettysburgAddress {
public Static void main(String[] args) {
String URLString = "http://cs.armstrong.edu/liang/Lincoln.txt";

I was browsing around and I found a question asking to find how many times a word occurred in a sentence. I am using a hashtable, over kill yes but I need to use them more. However my counter is not working, not really sure why.You can see in the main method I have two repeating names but it returns 0.
package frequency;
import java.util.Hashtable;
public class CheckFrequency {
hashtable<String, Word> words = new Hashtable<String, Word>();
[code]....

I tried the following code, OK:
Java Code:
String temp = "hi this sf hello is new what is this";
String[] cmd = temp.split("s");
int num = cmd.length;
System.out.println("number of words are: "+num); mh_sh_highlight_all('java');
However, when i get the input from user , i didnt get the expected result:
Java Code:
System.out.println("Enter the input string to count the words: ");
String[] cmd = new Scanner(System.in).next().trim().split("s");
int num = cmd.length;
System.out.println("number of words are: "+num); mh_sh_highlight_all('java');
Now Result for above code:
Enter the string to count the words:
hi this is new
words are: 1

Write a menu driven program that either accepts words and their meanings, or displays the list of words in lexicographical order (i.e. as in a dictionary). When an entry is to be added to the dictionary you must first enter the word as one string, and then enter the meaning as separate string. Another requirement - from time to time words become obsolete. When this happens, such word must be removed from the dictionary.
Use the JOptionPane class to enter the information.
Use the concept of linked list to carryout this exercise. You will need at minimum the following classes:
- A WordMeaning class that hold the name of a word and its meaning.
- A WordMeaningNode class that creates the node of information and its link field.
- A WordList class that creates and maintain a linked list of words and their meanings.
- A Dictionary class that test your classes.
For the output, the program should produce two scrollable lists:
- The current list of words and their meanings.
- The list of the deleted words. You need not list the meanings, just the words.
So far, I have everything coded except for the remove method, and I am not sure how to code that. I coded the add method already, but now I don't know where to begin with the remove method in my WordList class. My classes are below.
WordMeaning Class:
public class WordMeaning {
String name;
String definition;
WordMeaning(String t, String d) {
name = t;
definition = d;
[Code] .....

I need the user to enter the name of a file and check if the word is contained in the dictionary file.
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.util.Scanner;
public class SpellChecker{
public static void main(String[] args){
[code]....
I need to read the file and separate the words and save them in a collection after read another file and search each line for one of the words in the collection.

Returning true from getScrollableTracksViewportWidth() makes the table (or other Scrollable) size its width to match the viewport. I need the opposite: for the viewport to expand its width to accommodate the table (of course, limited by the constraints imposed by the scroll pane's container's layout manager) without reducing column widths i.e. setAutoResizeMode(AUTO_RESIZE_OFF).
I have achieved this by overriding
getPreferredScrollableViewportSize(): JTable table = new JTable() {
@Override
public Dimension getPreferredScrollableViewportSize() {
return new Dimension(super.getPreferredSize().width,
super.getPreferredScrollableViewportSize().height);
}
};
Now when the scroll pane is added at BorderLayout.CENTER and the frame is pack()ed, all columns of the table are displayed, without need for a horizontal scrollbar.

I'm not new to java but i'm not able to solve the following issue: I have a class
public class Localizzazioni implements java.io.Serializable {
private <complexType> id;
public getId().......
public setId().....
The complexType is a class defined in the code somewhere. Now I want to access it in another class I have
Set localizzazioni = new HashSet(0);
localizzazioni=opere.getOiLocalizzazioneOperas(); -- this object give an object of tyoe HashSet
for(Object object : localizzazioni) {
object.get......... // i cannot use any method defined in the class Localizzazioni
}
Why I cannot write inside the for object.getId() and using it?? In other word how i can access the element contained in the object?? the object is an iterator of type Localizzazioni . The class Localizzazioni has some method but i cannot use them? why ....

I have been working on this for hours and cannot get it to work properly. The program is to count the number of characters contained in both strings and display the results. It is also to display the final statement, but only once. This version has a complete statement for each matching character.
import java.util.Scanner;
public class CountMatches {
public static void main(String[] args) {
String firstStr = ("");
String s1 = firstStr;
[Code] ....

I am having an array of strings and i want to find out whether these strings contained in the array contain a similar character or not.For example i am having following strings in the array of string:
aadafbd
dsfgdfbvc
sdfgyub
fhjgbjhjd
my program should provide following result: 3 because i have 3 characters which are similar in all the strings of the array(f,b,d).

I just started using java because i want to create a simple web service that will take some values from within a url and save those values in variables.
To be more specific:
For my project I use the Spring Tool Suite.
I want to be able to enter a URL in a browser.. something like "localhost:8080/test?name=Root". When I hit Enter a page will be displayed showing "Hello Root" if the name in the URL is Root or "Hello User" for any other name.
I accomplish that with this code:
Java Code:
String UserName = "Empty";
@RequestMapping("/test")
public @ResponseBody String username(@RequestParam(value="name")String name){
if (name == "Root")
UserName = "Hello" + name;
else
UserName = "Hello User";
return UserName;
} mh_sh_highlight_all('java');
My problem is that it if I enter Root as a name in the URL it doesn't recognize it and it shows "Hello User".
I tried Java Code: << if (name.toString() == "Root") mh_sh_highlight_all('java'); but no luck.
How exactly I should reform this code in order to make it work?

I wrote a Chess game that uses socket to connect to another computer, and allow player vs player and player vs computer game sessions.
However, there is a problem which I noticed.
When you get the IP address of the computer in which the program is running, you are not getting the computer's actual IP, you are getting the Router's IP.
Is there a way to get around this.
So the problem is that when I go to another computer, located in a different house or lets say from my school, the program cannot connect back to my home IP, because it uses the router's ip, not the computer's ip I am running the server program.
Is there a way to get the Computer's IP, not the router's ip when summoning or invoking the get IP address method from the socket class?
When I say that the socket class is acquiring the router's ip, well that's done without my interfering...I don't know why it does that, it is somehow recognizing the router and not the computer.
The thing is that the server program is written that any client program is able to connect to the home server.
But when I run the program from a different location other than the current home, the sockets don't connect because it is somehow recognizing the router's ip not the computer's ip.

I am trying to build an address book, and I started from what i know how to do.
public class Persona {
String nome;
String indirizzo;
int cellulare;
public Persona(String nom, String ind, int cel) {
nome = nom;
indirizzo = ind;
cellulare = cel;
[code].....
Now I would like the program to take a string I insert on command line (for example java Cerca"Robert Baratheon") and compare it to the nome field of every Persona in the address book.

I found out what my next java class project is, and i am trying to get a head start on it. It is a simple address book. it needs to have 4 choices that get cycled through until quit is chosen:
1. add business contact
2. add personal contact
3. display contacts
4. quit
I have made an abstract contact class with a personal subclass and business subclass(all 3 are required). they have all been made, with set/get methods(the wonders of encapsulation and polymorphism have finally hit home!). The main program needs to add a new subclass object when chosen, and it needs to accept and store contacts by type
So, i am figuring 2 object arraylists for business/personal.
My question is: how do you create an object without having a name for it already programmed? Does it even need to have a unique name, since it would be stored in a seperate index and/or arraylist?
Contact contact = new Contact();
this.firstname = "Be";
this.secondname ="Ginner";
this.phonenumber = "921-456-0102";
personalArray.add (contact);
Then cycle through, changing the properties, and add again to personalArray?

System.out.println(" From: " + senderAddress); mh_sh_highlight_all('java');
Now i want to do something like

I have a question about arraylist objects.... I want to create an address book that will contain a persons information (name, phone, address, email..etc..). The first two snippets of code are from the same class ContactArrayList and the last one is from the class Contact. Do I need to create a separate arraylist for each data type? Is it possible to use a single arraylist to contain all the object (person) information and then be searched for using a GUI? I would also like to be able to access this data to be manipulated using a JFrame (add, edit, and search).
public class ContactArrayList<E> implements List<E> {
public int size, capacity;
E contact;
private E[] contacts;
public ContactArrayList() {
size = 0;
capacity = 20;
[Code] ....

I wanted to ask is there any way that Java code can get at the address of some object or other datum? I've found this useful a few time with certain high performance C# libraries that I've developed.
Also does Java have the equivalent of C#'s "fixed" buffers? which are inline contiguous arrays of primitives (like Chars or Ints etc).

I am trying to implement an example (Book* : Java SE 7 ..By S G Ganesh) for validating an IP address but it fails to validate a valid IP addresses. I found another example on the internet(**) and it works super fine, no problem at all. I edited the code (the one I got from internet) into the exact format like book and it still works super but i don't understand why the books' example doesn't work though both look exactly the same now ,further more, how can i compare String x and y for equality?
public class TestClass {
void validateIP(String ipStr) {
String one = "((25[0-5]|2[0-4]d|[01]?dd?)(.)){3}(25[0-5]|2[0-4]d|[01]?dd?)"; //copied from internet and edited
String two = "((25[0–5]|2[0–4]d|[01]?dd?)(.)){3}(25[0–5]|2[0–4]d|[01]?dd?)"; // copied from book
String x = "((25[0-5]|2[0-4]d|[01]?dd?)(.))";
String y ="((25[0–5]|2[0–4]d|[01]?dd?)(.))";

I'm trying to integrate google reverse geocoding address into my jsf application. I would like to be able to enter a postcode and hit a 'Find Address' button to bring me back all the addresses within that location. I have attempted the script below just to get something working in html then build a jsf2 page up. The results that I keep getting back are for a specific building rather than a list of houses within the same street. I think this is because I'm using the lat/long.
<!DOCTYPE html>

<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?sensor=false"></script>

Facing problem with java.net.InetAddress class while validating special form of IPv6 address.
Please check the following piece of code.
String ipv6 = "0:0:0:0:0:ffff:a1f:e403";
try{
final Inet6Address i6 = (Inet6Address) InetAddress.getByName(ipv6);
System.out.println(i6);
}
catch(ClassCastException e){
System.out.println("Not a proper ip: "+e);
}
It is throwing ClassCastException.
