JSF :: Rewriting URLs - User Friendly Links
Jul 1, 2014
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?

public static void main(String[] args) {
String htmlCode = (long string of url links)
int linkStart = 0;
while (true) {

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);

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 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.

import java.util.Scanner;
public class Project_5
{
public static void main (String[] args)
{
Scanner input= new Scanner (System.in);
[code]....
So I'm attempting to have this program take the users input of integers, pressing enter in between each one. If they enter a negative number it lets them know that its invalid. At the end of the program it takes all of the valid integers entered and must add them and average them. I've put the final println in there as a placeholder. If the user types in "6" then presses enter and types in "3" , the output is:
There were 3 valid numbers entered.
The sum of the valid numbers was --- and the average was ---.
There were 0 invalid numbers entered.
It then continues on allowing the user to enter more values. Here is the example output for correct code"
Enter a positive value (EOF to quit): 4
Enter a positive value (EOF to quit): 7
Enter a positive value (EOF to quit): 8
Enter a positive value (EOF to quit): 2
Enter a positive value (EOF to quit): -1
The number "-1" is invalid.
Enter a positive value (EOF to quit): 8
Enter a positive value (EOF to quit): 0
Enter a positive value (EOF to quit): -4
The number "-4" is invalid.
Enter a positive value (EOF to quit): CTRL-D
There were 6 valid numbers entered.
The sum of the valid numbers was 29 and the average was 4.83.
There were 2 invalid numbers.

Write a java program that will ask a user to input grades until the user inputs the sentinel value -1. The program should test each input to determine whether 0<=grade<=100. If the grade entered is within this range, the program should print "Grade accepted;" if not, the program should print "Invalid input".

Basically I need to make a program prompts the user for an integer, check to make sure the length entered by the user is a power of 2 and at least 2. Then I need to convert from base e to base 2 then I need to print the tick marks of a ruler based of the value of the length.
I got the whole converting thing working and the check for a power of 2, that wasn't an issue because it didn't require any recursion. I just don't know how to print out the proper tick mark values.
The way it is supposed to work is that it needs to look like this. Say the user enters 8;
012131210
012345678
Or if the user enters 16;
01213121412131210
01234567890123456
The bottom row is pretty much just the index value, that I print fine.
The top row though is supposed to be the length of the ticks on a ruler, with the middle most value being the value of the conversion from base e to base 2 from above. I can get that printed and what I get just looks like this.
For 8;
000030000
012345678
For 16;
00000000400000000
01234567890123456
As you can see I can get the middle value and the index values below but I don't know how to use recursion to get the right numbers.
Here's my current code.
import java.util.*;
public class TickMarks {
public static void main (String args[]){
Scanner input = new Scanner(System.in);
boolean looping = true;
while(looping == true){
System.out.print("Please enter a length: ");
[Code]...
Now the methods isPowerOfTwo() and printLength() both work fine. However, I'm not sure how to get the left and right side working.
My thoughts were to split the length in half and get a left and right side. I gave both of them arrays so I can keep track of the values. Now as you've seen above I get all zeros and I know it's because that's the default value in an array, I just don't know how to get the proper values.

I have been coding in my class at school (Grade 11 Computer science) and i just downloaded the program on my computer at home, unfortunately i cannot access my computer notes at home and i also dont remember certian specifics of coding, so my question is how would i get user input to create a program. The comments are the parts i dont remember. (I am trying to slowly build my memory with this stuff)
Here is my code so far:
import java.util;
[highlight=java]
public class hello_world {
public static void main(String[] args) {
string name;
//WHAT DO I PUT HERE????

I'm working on creating a dice game and getting the users input is giving me a really hard time. I have the main game working but this part I'm stuck on. The problem is that it's not giving me the chance to enter the second input when I ask for the game.
//Create Scanner object
Scanner keys = new Scanner(System.in);
//Get chips
[Code]....
*****This is what I get when I run it
run:
How much money would you like to change? 50
You now have $50 in chips.
What game do you want to play? You did not pick dice.

Program is running fine. I can create usernames and everything but somehow I cannot quit or exit the program when I enter my sentinal value "QUIT". Here is my program question: Create an application that will create a username for a school computer system. Input a user’s first and last name. The username will be the first letter of the first name followed by the first 5 letters of his last name followed by a random 3 digit number. Continue to create and display usernames until a sentinel value is entered.
import java.text.*;
import java.util.Random;
import java.text.DecimalFormat;

Is there a way you can control user input?
For example, is it possible to only allow the user to enter digits?

I have been given a piece of work to do for College that requires me to format user input. For example: This is an example of text that will have straight left and right margins after formatting
will transform into:
This..is..an.example
of..text..that..will
have..straight..left
and...right..margins
after.....formatting
The user inputs the width, in the case above being 20. Each line has to therefore be 20 characters long. All spaces are to be replaced with full stops.
This.is.an.example.o
f.text.that.will.hav
e.straight.left.and.
right.margins.after.
formatting..........

public static void main ( String args[])

Goal is to get user input and sum together. I've tried it different ways. This is the one with the least amount of problems.
Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - Erroneous sym type: java.lang.Integer.parseInt

I created a scanner object but it's not asking for any input. when I create a new scanner and then tell it to print it it just prints a bunch of weirdness when AFIK it should be asking me to type something and then it should repeat what i entered.

Here is my problem to solve : Find the smallest value Write an application that finds the smallest of several integers. Assume that the first value read specifies the number of values to input from the user.
I do not even know where to begin other than creating a scanner for the user input. But how do I take that user inputed number to create the loop?
