we don't do homeworks here.
Read the guidelines, try to do the work yourself first, and ask for specific question only when you're stuck on something.
If you cannot do anything at all, then you're not the one for the job...

for the programmin task,you are going to a simple application which allows 2 people 2 play tic tac toe. you will have 3 major classes as defined. each class should go in its own file.
1.Player:
*represent a player in the game
*it should have following constructor:pulic player(string name, char symbol)
*the class whould have 2 properties:name and symbol.
2.Board:
*represent the board on which tic tac toe is played.
*it should have 1 data properties,a 3*3 array which represnets the playing area.
*it should have the following constructor:public board(),which initilizes the data property to be an empty board.
*At a minimum,it should have the following methods:# public void printBoard()#public boolean isFull()#public boolean isWinner(Player player)#public boolean setpiece(int row,int col)
3.Game:
*contains the main()
*prompts the users for their name
*must use the player and board classes to manage the game.
*should report who the winner is , or if the game was a tie.

Enclose that line in a try{}catch(){} block and see if there is an error being generated.

I hope someone can help me out here. I am not that familiar with JS and I found this script online which I modified, but I can not control how to open the links. All the links open in the same window but I have some external links that I have to open in a new window.
Here is an example of what I have:
bar.addMenu('Insulated Glass');
bar.addItem('http://www.associatedmaterials.net/Docs/glass_specs/Units.pdf','IG Quality');
I would appreciate any help.

Please do a Google search for Javascript.
As far as anchor tag attributes, you want "target=_blank". The anchor tag [<a...>~</a>] is not Javascript, but HTML.

You need to goto www.rentacoder.com for that. Or with such a simple app, you could even just Google it.

What exactly is wrong with Eclipse? There are plenty other out there, but I couldn't begin to suggest without knowing what is wrong with the one you use now. I prefer Eclipse myself anyway.

You could always try the one that Sun provides if you download the right Java bundle. I believe they call it Netbeans. (http://www.netbeans.org/downloads/index.html[^])
I've played with it, but I prefer to use Eclipse myself.

I cannot advise better than the other answer you got. to me, Eclipse is the best IDE for Java/J2EE I know...

need help in writng a class WordStore in order to compile WordTest1, WordTest2, WordTest3 and WordTest4. Need to create some sort of data structure to store words in WordStore. must have methods
public void add(String word)
Adds a String to the collection
public int count(String word)
Returns the number of times a String is in the collection
public void remove(String word)
Removes one occurrence of a String from the collection, or leaves the collection unchanged if the String does not occur in it.
code for WordTest1:
import java.util.Scanner;
class WordTest1
{
public static void main(String[] args)
{
Scanner input = new Scanner(System.in);
WordGen.initialise(input);
System.out.print("Enter the number of words you wish to generate: ");
int n = input.nextInt();
WordStore words = new WordStore(n);
for(int i=0; i<n;> words.add(WordGen.make());
String line = input.nextLine();
System.out.println("Enter words to test, empty line to exit");
line = input.nextLine();
while(!line.equals(""))
{
String[] wordlist = line.split(" ");
for(int i=0; i<wordlist.length;> {
int count = words.count(wordlist[i]);
System.out.print("\""+wordlist[i]+"\" ");
if(count==0)
System.out.println("NOT generated");
else if(count==1)
System.out.println("generated once");
else
System.out.println("generated "+count+" times ");
}
line = input.nextLine();
}
}
}
code for WordTest2:
import java.util.*;
class WordTest2
{
public static void main(String[] args)
{
Scanner input = new Scanner(System.in);
WordGen.initialise(input);
System.out.print("Enter the number of words you wish to generate initially: ");
int n = input.nextInt();
WordStore words = new WordStore(n);
for(int i=0; i<n;> words.add(WordGen.make());
System.out.print("Enter number of words you wish to test: ");
n = input.nextInt();
String[] testWords = new String[n];
for(int i=0; i<n;> testWords[i]=WordGen.make();
long time1,time2;
int count;
time1 = new Date().getTime();
for(int i=0; i<n;> count=words.count(testWords[i]);
time2 = new Date().getTime();
System.out.print("Time taken to test membership of "+n+" words ");
System.out.println("is "+(time2-time1)+"ms");
}
}
code for WordTest3:
import java.util.*;
class WordTest3
{
public static void main(String[] args)
{
Scanner input = new Scanner(System.in);
WordGen.initialise(input);

time1 = new Date().getTime();
for(int i=0; i<n;> words.add(testWords[i]);
time2 = new Date().getTime();
System.out.print("Time taken to add "+n+" more words ");
System.out.println("is "+(time2-time1)+"ms");
}
}
code for WordTest4:
import java.util.*;
class WordTest3
{
public static void main(String[] args)
{
Scanner input = new Scanner(System.in);
WordGen.initialise(input);
System.out.print("Enter the number of words you wish to generate initially: ");

I assume this is a standard 3-wheel slot machine?
You should have a "slot" object defined somewhere, or at least some member variables to hold the "shape" and "color" values of each slot wheel.
The "if" statements aren't writable until we know what to compare them with.
For example, would it be "if (slot1Color == 0)" or "if (slot1.color == Color.RED)" or something else?
All you have written is a skeleton application. None of that concerns the question you wanted help with.
Don't let my name fool you. That's my job.
