I need open a url every time I want to refresh system with an update. Each update has a number so my urls are url1, url2, url3, ... I know how to put it in a loop to increment the urls in a String. I do not know how to make it open and close the url in a browser.
public class Test {
public static void main( String args[]) {
for (int i = 201; i < 300; i++){
System.out.println("http://url=" + i);
[Code]....
My program is pretty much finished and does what it is supposed to do but it is displaying the href= with the url link how can i get my program to drop the href= from the url link because it is only supposed to display 'url' right now it is just displaying href='url' ...
public class myList {
public static void main(String[] args) {
String htmlCode = (long string of url links)
int linkStart = 0;
while (true) {
linkStart = hrefSearch(htmlCode);
if(linkStart == -1) {break;}

I try to use ‘rewrite’ [URL] .... in my JSF application. So, I want to show user friendly links. For example, I have /viewpage.xhtml?id=5 page, but I want to show /page/5 or, more better /page/{page-title} . How can I reach this functionality?
View Replies View RelatedI have a question related to the code below, that I do not understand. The aim is to count all files and subdirectories in an ArrayList full of files and subdirectories. So I have to count every file and every subdirectory.
The code concerning counting files is clear to me - every time d is of the type file I have to increment n by one. However I thought that I have to do the same thing in case d is a directory, so I would have written the same code for directories.
So what does "n += ((Directory) d).countAllFiles();" mean? In my understanding the method countAllFiles() is applied again on the object Directory ( as Directory is the class that contains this method), but how is n incremented by this? I thought n should be incremented by one as we did with files.
public int countAllFiles() {
int n = 0;
for(SystemFile d : content) {
if(d instanceof File) {
n++;

I'm attempting to increment the values by 1 in an array of objects but I'm not able to increment with the increment operator.
for(int i=1;i<a.length;i++){
a[i].getHour(); hour = hour++;
a[i].getMin(); miinute = minute++;
a[i].getSec(); sec = sec++;
}
It just loops the value of hour without incrementing.
I'm trying to display an columns and rows. The first column has integers and the rest are doubles. The initial calculations are correct, but I cannot figure out how to total last column, which is interest paid, and then start the iteration over.
int paymentNumber;
//print out the colum labels
System.out.printf("%7s %9s %10s %8s %15s %n", "Payment", "Interest"
, "Principal", "Balance", "Interest Paid");
System.out.print(" "); //put three blank spaces first
//Test For Loop Output:
for ( paymentNumber = 1; paymentNumber <= period*12; paymentNumber++) {
[Code] .....
Here's the output: It displays the payment number correctly. Am I supposed to write a for loop for each column?
run:
Please enter the amount of the loan:
1000
Please enter the interest rate:
1
Please enter the loan period in years.
1
Your Monthly Payment is:$83.79

I have the following:
public class HistoricalMoment{
private String eventName;
private ClockDisplay timeOfEvent;
public static final int MIDNIGHT_HOUR = 00;

How can I create a method called public void addMinuteToTimeOfEvent() which calls the timeOfEvent's increment() method to add one minute to the timeOfEvent?
I have a code issue and I have a below question for the same.Assuming data[] is of type byte[], is the below statement in java -
while((data[p++] & 0x80) == 0x80);
same as -
while ( (data[p] & 0x80) == 0x80 ) { p++; }
I tried with do { p++; } while ( (data[p] & 0x80) == 0x80 ); That also doesn't seem to be the same thing. I am not putting code around this but essentially if I make this change for not using data[p++] code stops working!

The program shall assign a new employee ID to the employee and display it on the screen.
The employee ID shall be generated by adding 1 to the largest employee ID already in the employee.txt data file.
You can see I've tried variations of identification++ but have not been successful. I've also tried to get the last or the highest identification in the arrayList but have not done that right.
public static void addEmployee() {
String firstName = Validator.getString(
sc, "Enter First Name: ");
String lastName = Validator.getString(
sc, "Enter Last Name: ");
int identification = 0;
[Code] ....
I also can display all of the employees their identifications and their punches but I cannot narrow it down to searching one employee and displaying information for just the one.
-If the selected value is ‘I’, prompt the user to enter the employee’s ID number.
-If ‘I’ is selected the display shall show the employee’s name and ID, list out each day worked in chronological order, the number of hours worked that day and a total number of hours worked in the two week period.
The report shall prompt the user to re-enter an employee ID of it does not exist in the employee file.

So I'm trying to make a bar graph, each bar will increment the height by about 10 pixels. To do this, I'm making an array of bars. For some reason, using fillrect I cannot not increase the size more than 10 by 10, if I do, it will only show the 10 by 10. I want the bars to increase in height by 10 each time.

I've a simple logic Code to increment a variable from javascript and Send it back to jsp. I just writing simple code to explain the logic. My code will have scritplets. I know usage of scriptlets is inside jsp is oldest but for the sake of logic.

<!-- Script as Follows-->

function fun(){

if I move object A to one area of the screen I want object B to to move to object A's location but I also want object B to move at a fixed speed (movement variable). How do I go about doing this? Both the x and y coordinates of object B would need to know the coordinates of object A to calculate the distance between the two and to determine how much of which axis to increment/decrement (if that makes sense?) with the inclusion of the speed variable.In other words I'm just trying to create a homing object.
View Replies View RelatedSo I need to make a for loop for this problem: A certain type of bacteria doubles its population every twelve hours. If you start with a population of 1000, how many hours will it take for the population to exceed 1,000,000? Output needs to be in table format, such as:
Hours: - Population:

I created my own class and it basically randomizes the amount of 'spells' [magic] a user uses (range 1-5). I can't figure out how to increment the initial randomized output to make something like this :
User X : uses 2 spell.
User Y : uses 3 spells.
User X : uses 3 spells. (Taking the randomized 2 and increment by 1)
User Y : uses 4 spells. (Taking the randomized 3 and increment by 1)
My current setup looks like this : First one is the class I created and the second one is just how the output would look like. (seperate by +++++...)
My goal is to create a METHOD to increment it.
public class Spell {
// Max number of spells
private final int MAX_FACE_VALUE = 5;
// Current face value
private int faceValue;
// New instance of Spell
public Spell() {
faceValue = 1;

Basically I'm looking for a way to make one object follow another. For example, if I move object A to one area of the screen I want object B to to move to object A's location but I also want object B to move at a fixed speed (movement variable). How do I go about doing this?
Both the x and y coordinates of object B would need to know the coordinates of object A to calculate the distance between the two and to determine how much of which axis to increment/decrement (if that makes sense?) with the inclusion of the speed variable.

The problem is that I populate the table with autoincrement primary key. I don't want it to be visible. I have been googling for hours to find no solution. It seems that sql/mysql provides no solution by selecting all table columns except one. So I wonder, how I could overcome this problem. Here is some of my code:
public void tableChanged(TableModelEvent e) {
int row = e.getFirstRow();
int col = e.getColumn();
model = (MyTableModel) e.getSource();
String stulpPav = model.getColumnName(col);
Object data = model.getValueAt(row, col);
[Code] .....
The ID is used in
stmt.addBatch("update finance.fin set " + stulpPav + " = " + duom
+ " where ID = " + studId + ";");
I tried to omit ID from my SELECT statement, I tried to put Date as a first element in data[iEil][0] but neither options were successful. Data hasn't been changed in database. NOW, everything works fine, except I don't want ID column to be visible in my table.
How can I write a method that takes a string with duplicates letters and returns the same string which does not contain duplicates. For example, if you pass it radar, it will return rad. Also i would like to know how can I Write a method that takes as parameters the secret word and the good guesses and returns a string that is the secretword but has dashes in the places where the player has not yet guessed that letter. For example, if the secret word is radar and the player has already guessed the good guesses letters r and d, the method will return r-d-r.
