Any Way To Stop Duplicate Links From Getting Put In ArrayList
Oct 5, 2014
I am making a WebCrawler, and I am trying to work out a way to stop duplicate links from getting put in however ArrayList.contains() doesnt seem to be working for me can someone look at my code and see if I am doing something wrong? I have also tried variations of it such as
!link.contains(newLink)
and
!link.contains(newLink.getLinkUrl())
with no luck. The Problem area is
for(Element lnks: link){
linkSrc = lnks.absUrl("href");
WebPage newLink = new WebPage(linkSrc);
if(!link.contains(linkSrc)){
links.add(newLink);
[Code] .....

I have a java file 'Arithmetic.java', in which i have 2 overridden method.Now i wanted to read this file and i need to print all the method signature lines,if i found same(overridden method)signature then i have to print "overridden method found". once i find the overridden method i have to suffix the method name as methodName_overridden1, methodName_overridden2 and so on...
package com.abcd.arithmetic;
public class AllArithmatic
{
public Integer add(int x,int y,int z)
{
return (x+y-z);
}
public Float substract(float x, float y)
[code]....
till now i am able to read the lines, able to read the method names as well. but while putting the entire method signatures into an string array and the suffixing part , i am not able to proceed. The condition i have put to find out oerridden method is nnot working.i am stucked in comparing the duplicate method
//Finds Method Name, Method Return Type
if(indexOfMethod >-1 && indexOfOpenBrace >-1){
int uniqueWordsInFile=0;
//Method signature Start
//System.out.println("method line="+line.trim());
List<String> methodList = new ArrayList<String>();
methodList.add(line.trim());
[code]....

I have a random list of links whose title I am getting from the database. I'd like to catch one of these links when the user clicks one of them and process it from a single jsp file. Possible?
<ul>
<%
Random random=new Random();
TreeSet<Integer> ts=new TreeSet<Integer>();
for(int i=0;i<8;i++) {
randomInteger=al.get(random.nextInt(al.size()));
ts.add(randomInteger);
[Code] ....
E.g.: when user clicks one of these links, can I dynamically call a web page that fetches information from the click and gets values from a database and insert it on JSP page....

In a project for school. I have a program that links several GUI's as a menu based program. What I am trying to accomplish is when one of the previous GUI's is closed that it doesn't terminate the entire program. There is a lot of classes in the entire project so I'd prefer not to paste all the code here, but if it is necessary I will do so.

How can i check the reference that is not duplicate and date format is DDDCCYYnnnnnnn, CC must be 20 and YY must not be less than the current year, nnnnnnn is the sequetial number of the file and to complete the 7 numeric characters, zero's must be populated in front of the number. DDD must be a valid reporting entity code. there must not be a duplicate. Code I try
private boolean test-date()
{
String s_Ref = this.transactionFile.getsReference();
boolean flag = true;
if(!isValidPattern(s_Ref, "[0-9]{14}"))
[Code] ....
The reference number is like 201401030234509

I am having some difficulty adding a new item to the HashTable when a collision occurs. We can only use the basic utilities to code this, so we are coding a HashTable by hand. We have an array of length of 10, which each index holds or will hold a Node for a Linked List.
The code hashes fine, adds the item, but the problem exists when adding items that already been hashed. The project is much bigger, but this is the engine behind the rest, and I figured I would tackle this first.
The items we are adding are objects which are states containing different information, we hash based on the ASCII sum % tableSize.
Here is the code I am testing with to add items:
HashTable ht = new HashTable(10);
State az = new State("Arizona","AZ","W",2,"Y",2);
State fl = new State("Florida", "FL", "F", 2, "X", 2);
State hi = new State("Hawaii", "HI", "H", 3, "Z", 1);
State al = new State("Alabama", "AL", "A", 5, "W", 0);
ht.insert(hi);

I was trying remove duplicates element from my array without using collection API but i didn't got any output from my code.Although it is compiled successfully but on execution it didn't give any output. I guess there must be some problem in function Duplicate
Java Code:
class Union {
public static void main(String...s) {
Union M=new Union();
int x[]=new int[]{1,0,1,4,10,10,10,3,567,4,3,33};
int y[]=new int[]{5,4,5,4,5,4,2,3,3,1,0};
int []w=M.merge(x,y);

I need to know how many four letter strings I can generate that begin with the letter "v". Now I had been testing many ways to do this but anm stuck. I can generate a single line up only a certain amount. I need it to continue till it reaches the max number. So since it needs to always start with V i eliminated the need for four and only a 3 letter string.
package javaapplication4;
import java.util.Random;
public class JavaApplication4 {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
Random r = new Random();
int c = r.nextInt(26)+ (byte)'a';

In the code that I am currently trying to do, I want to make it so that the program loops until the randomly generated number is 1, to a maximum of 4 loops.I have figured out how to make it stop at a randomly generated 1, but I can't quite figure out how to make it stop at four loops if it doesn't reach the 1 before the maximum number of loops.

I am working on this project that wants me to write a program that inputs 20 numbers, each of which is between 10 and 100, inclusive. As each number is read, display it only if it is not a duplicate of a number already read. The only part I am confused about is how to go about checking for duplicate values that the user may enter. And IF the user does input a duplicate value, it should not be stored again.In addition, the value entered should be printed out after it is entered along side the value that have been previously entered by the user such as:
23
23 45
23 45 67
23 45 67 12
and so on.
I am still fairly new at java programming.
import java.util.*;
public class NumberArray
{
public static void main(String[] args) {
// declare an array with 5 elements

I have a practice program (written with NetBeans IDE 7.4) that calls methods to:
(1) fill an array with user input values
(2) sort the array values into ascending order
(3) print the array in assorted order.
(4) print the array without any duplicates
Method (4) prints the contents of the array without printing any duplicates. That is, if a number in the array has already been printed, it will not be printed again.
Method (4) seems to work, but may be inefficient or I may have done too much work making it difficult on myself or making the logic too confusing.
Is there a better way to do this WITHOUT using built-in functions in Java's library?
(Such as writing this method using for loops and counter variables: As practice I am supposed to avoid using Deleting functions for duplicates)
Here is my code:
public static void Duplicates(int [] array){
int duplicates = 1;
String Output = "";
for(int i = 0; i < array.length -1; i++) {
if (array[i] != array[i+1]){
duplicates ++;

how many integers the user wants to use. The user will enter for example a 4. The user inputs a 2, 4, 6, and 10. So then we get our outputs...Then the code will ask if you want to run this program again. My question is, if the user inputs a -1 for example 2, 4, 6, -1....the code will not continue. I wanted to use a while loop, such as while (scores != -1) but it doesn't work.
Enter the amount of integers you want to use4
Intenger # 1 2
Intenger # 2 4
Intenger # 3 6
Intenger # 4 10
You entered 2.0 4.0 6.0 10.0
Average = 5.5
Variance = 8.75
Standard Deviation = 2.96
Do you have another set of numbers?

I am making a project that should play, stop, and loop three different songs (not at the same time). I am calling this SoundPlayer class from my main class:
import javax.sound.sampled.*;
import java.util.*;
public class SoundPlayer {
List<AudioInputStream> songs = new ArrayList<AudioInputStream>();
int currentSong, currentPlayType;
[Code] ....
When my class calls setPlayType(2), which should make it play, I get the following runtime error:
java.lang.NullPointerException
at SoundPlayer.playSong(SoundPlayer.java:32)
at SoundPlayer.setPlayType(SoundPlayer.java:64)
at MainPanel$AListener.actionPerformed(MainPanel.java:60)
(...)
Line 32 is if(clip.isOpen()), but I'm pretty sure I instantiated clip properly in the constructor.

I am trying to program a slot machine and as of now, I am trying to make my slots spin and randomly stop on one of the graphics. Right now, I am having difficultly making the animation/slot stop randomly.
Previously, I tried using a randomly set timer that would cancel the execution, but the image did not appear/stop on the screen.Right now, I am using a random generator and a while to say that if it is a certain number, then stop the image.Here's what I tried:
import java.applet.*;
import java.awt.*;
import hsa.*;
import java.util.Random;
public class SlotGraphics
{
Console c;
int x = 200;
int y = -100;
