Write the methods with the following integers:
public static int reverse(int number)
//return true if a palindrome
public static Boolean isPalindrome(int number)
When I compile it says it cannot find symbol "remainder".
import java.util.*;
public class PalindromeInteger
{
public static void main(String[] args)
{
//Create a scanner
Scanner input = new Scanner(System.in);
[code]....
I have written a piece of code that takes a desired input file and calculates things such as words, characters, digits etc. I would like to make the program look better by counting palindromes.what I could add to my current code to count palindromes.My current code for counting other things that I would like to add plaindromes to.
// Loops through the file calculating the outcome.
while (input.hasNextLine()) {
lines++;
String line = input.nextLine();
chars += line.length();

I just started studying recursion and I wanted to know how to create a palindrome number going up from 1 to n then back to 1 like this: "12345...n...54321".
I've done one going downwards and then upwards like this: "n...4321234...n".
Here's my code:
Java Code: import java.util.*;
public class PalindromeTest
{
public static void downPalindrome(int n)

I'm trying to create a class that takes an String from a Stack and checking if it's a palindrome than taking a another String from a queue and checking if that is also a palindrome.
import java.util.Stack;
public class Palindrome {
public static void main(String[] args) {
// TODO Auto-generated method stub
String enteredLine;
int leftStack, rightStack;
int leftQueue, rightQueue;
PalinedromeArray stack1 = new PalinedromeArray();

i am trying to make something, and i want to request input from user and it shoud look like this
1. xxx -> press 1 to choose this
2. xxx -> press 2 to choose this
So if they enter 3 or string or whatever i want to restart method and show again
1. xxx -> press 1 to choose this
2. xxx -> press 2 to choose this
So here is method that i am trying to restart
public static void askUser(){
System.out.println("xxx");
System.out.println("1. xxx");
System.out.println("2. xxx");
System.out.println("3. xxx");

If i try to make it public void than it say can't call non-static methods inside static(main).if i try to put it into new class and then call it after i fail input it goes into infinite loop.
Here's what "Why doesn't this work?" question. It concerns a small method which is part of a card game.
I'm trying to check a condition from a section of an array, without a predetermined number of times any given call to this method will require a check. How much of the array I'm checking could vary greatly.
Is it at all possible to nest a for loop yielding a variable number of boolean && conditions inside an if? Am I just missing the right bracketing or is this nesting (if that's the word) even possible in the language?
To clarify, below is broken code. Compiler isn't letting me accomplish this goal as I envision it.
public boolean isFlanking() {
boolean f;
int reach = Math.abs(selectorX - targetX);
if(rival.getDeck()[selectorX].getPile().isEmpty() == true &&

Basically the problem is I've been trying to loop my switch (if this is even possible) until the user enters a correct number between 1 and 4. But for some reason when the user enters a correct number (1,2,3,4) the loop runs again. Even when the user enters a wrong number the switch ignores the default and repeats what is in the do.
Am I just trying to loop something that cannot be looped or have I gone?
import java.util.Scanner;
class mammals {
int age;
int death;
String name;

Basically, I am trying to write a method that will take a string, a target, and a replacement (a replacement function like string.replace). I want it to replace all instances of target with replacement EXCEPT for instances that occur within single or double quotes.
Example input / output:
this "Wont" be " replaced, be"
call: replace(theString, "replaced", "narf") and replace(theString, "be", "rafn")
output:
this "Wont" rafn " replaced, be"
In some examples I see jsf components inside the tag view, other times dont.
- Is it important to put all jsf components inside "the view" tag?
- What would be the difference not putting them inside this tag?
Write a program that accepts as input three positive integers representing the diameter of the cigarettes to be packed and the dimensions of the pack to be used. The required output is the maximum number of cigarettes that can be packed without damaging/re-sizing the cigarettes or packs
NOTE: the diameter of cigarette is 1 and 2 only.
Example: Diameter is: 1 and dimension1: 2 and dimension2: 4
the output is. Maximum number of cigarettes can be put on the pack is 6.
ex.2 diameter is 2 and dimension is 10 and dimension2 is 17
the output is. The maximum number of cigarettes can be put on pack is 40.
ex.3 diameter is 2 and dimension is 5 and dimension2 is 7
the output is. The maximum number of cigarettes can be put on pack is 6.
I just need the formula to get the number of cigarettes that can be put inside on the pack on its dimension.
I have a datagrid in which i have to display progress bar with the task completed in %.
For example i have two fields in a table source count and completion count.
Where source count in 100000 rows and 50000 rows have been inserted.
In another table and status is displayed in the table.
So I need to display in a progress bar that 50% task has been completed.
I have a Jframe and i want to add inside 4 different jpanel.This is easy.
what is difficult is how can i change them dynamically with 4 other new jpanels and 4 other new jpanels?
I have try with BorderLayout but not working.
It's a wizard like but not the same.
I have a jpanel with jbuttons jpanel with a jtable jpanel with textarea and jpanel with jlabels. All this have to change with other 4 jpanels, where to look?
using richface 4.
#{rich:element('detailsTable'#{id.No})})
showing syntax error.How to pass the value #{id.No} inside rich:element
When are we allowed to nest interfaces inside a class? Would this be possible? Why or Why not?
View Replies View RelatedAs I couldn't find a way to do the printing of multiple items on one page, I decided to test out my idea. I found that I could have a table in a JTextPane.
However, whenever I got to print, my table will vanish. It doesn't even need to go to the printer. Just bringing up the print dialog will make it vanish like tax money in D.C.
(Also, I'm not really that familiar with JTextPane and it seems harder than JTextArea. Which part is controlling the font of my regular text by the way? I think it might be tableParagraph but it could also be the base font. I can try and fiddle with both and waste paper but where the font is being set.
Setting the font with setFont() will vanish my table. )
Somehow, I'm thinking that the solution might be JTextPane.setContentType() or setEditorKit() or both. (I"m not that familiar with either, but I fear that it's only being set to handle text, hence any graphics are being lost.)
Here is my code:
import java.awt.*;
import javax.swing.*;
import javax.swing.table.*;
import javax.swing.text.*;
public class AddingTables {
JTextPane textPane;
private Object[][] rows;
private Object[] colNames;

I want to put my table inside a form for retrieval purposes (or Am i doing it wrong?) When the table is not within a form, it works perfectly. It displays information the way i wanted.
However, once I put the table inside a form the table doesn't display needed information. Is the problem the html or the jsp code?
Here's my jsp file:
<form action="deletemovie" method="GET" id="deleteForm">
<table class="table table-striped table-responsive table-hover">
<thead>
<tr>
<td>Movie ID</td>
<td>Movie Title</td>

View Replies View RelatedWhen this program runs it gives me
workbook.Contact@46e5590e
Number of contact: 1
The number of Contact that I input is just one when I run the program so the Number of contacts: 1 is correct, but it gives me workbook.Contact@46e5590e instead of printing out all the contacts stored inside the Contact class. Yes I do loop through the ArrayList and I also have a method inside the Contact class, the printNameAndPhone(), which prints out the name as well as the phone number but how do I incorporate the printNameAndPhone() method (located in the Contact class) inside the print() method (located inside the AddressBook class)???

Ok say you have
public class MyClass {
private int x = 5;
Object myObject = new Object();
public MyClass(){
}
}
When would the myObject be created? Before or after the constructor? And does this mean you can't pass
this into the parameters of that object?
If we have request which hit the server, before it reaches servlet or the response going to send the browsers, through how many components it pass through (or the process flow).

View Replies View RelatedI am using netbeans swing to do my little project . I have one table which is populated by data from a database. I also have another table which should be populated when a user selects a certain row in the first table.Both table have only one column. The logic is when a user selects on row 1,the data in that row should be obtained and should be used to search for certain entities in the database which are returned and used to populate table 2.So after a user selects row1 and decides to select row2 the second table should be updated accordingly.

My Issue is that after creating the objects within the switch statement, is there a way to return the objects back to the main method once created within the switch ?
I am not able to understand how we are able to create an object of static inner class defined inside an interface .
interface outer {
class inner {
void disp() {
System.out.println("inside disp");

output:
inside disp
How am i able to create a new object for static class?
