Any simplest code to check whether a number is palindrome or not?
View Replies View RelatedI have the following code to check for five characters palindrome but it always give me incorrect answer that if i have a word like radar the answer it isn't a palindrome. and if i changed any thing in the code i got either stack overflow or index out of bounds exception
The code is as the following
import java.util.Scanner;
public class Palindrome {
int first =0;
static int n;
int last = 4;
int y = 0;
public static void main(String [] args)

I recently have tryed to make a java code that reads words and say if its palindrome or not. I want to fix two things but unfortunately i can't do it on my own.
1st thing that i want fix is that when i run the code i have to press 2x times enter..and i dont know why?(i want one time to press it when i write the text)
2nd thing that i want to fix is that when you run it you can put as many words as you can..only when you write "END" the code must ends.
So unfortunately my code runs only for 1 time.(one word)
My code:
class test {
public static void main(String args[]) {
System.out.print( "#Enter text : " );
String text = BIO.getString();
String reverse = BIO.getString();
int length = text.length();
[Code] .....
I'm supposed to use stacks (implemented with an array) to check to see if a string is a palindrome. I've finished all my classes and methods, but I'm getting an ArrayIndexOutOfBoundsException when I try to run my demo program.Here are my classes:
public interface Stack {
// Creates an empty stack
public void initializeStack()
// Returns true if the stack is empty, returns false otherwise
public boolean isEmpty();
// The stack can never be full, so always return false
public boolean isFullStack();

I have a simple code to test palindrome. I have the word "civic" and I got this code:
public String isPalindrome(String word) {
StringBuilder builder = new StringBuilder(word);
String reversed = builder.reverse().toString();
String s = new String();
if(reversed.equalsIgnoreCase(word)){
s = "Word " + parameters + " evitative is a palindrome!";
}
return s;
}
to my surprise, the if() condition is false even though the word is a palindrome.
I have to write a program that inputs a string and tests whether or not it is a palindrome. This worked fine, and now I want to make it so I continually enter strings until I tell the program to stop.
The code below compiles just fine, but it doesn't do what I want. Why it doesn't work how I think it should work? (Typing in STOP does not make the program stop.)
Here is the code
import javax.swing.JOptionPane;
public class PalTest {
public static void main(String[] args){
String S="pony";
while(S!="STOP"){
S=JOptionPane.showInputDialog("Enter a string (STOP to terminate):");

I cant figure out something in my code. I have to check whether given doubly linked list is palindrome or not. If it is palindrome it should print 1 , if not -1. My code has no errors but it always prints -1. I tried debugging but first comparisongives always false and function cant reach to else statement.
Are there any logical errors or i cant do right way of comparison?
import java.util.Scanner;
class DLLNode<E> {
protected E element;
protected DLLNode<E> pred, succ;
public DLLNode(E elem, DLLNode<E> pred, DLLNode<E> succ) {
this.element = elem;
this.pred = pred;
this.succ = succ;

I'm in the process of writing a program that determines if a number is a Palindrome or not. I'm not allowed to use strings and am required to use the getSize method shown below. I believe my issue that I'm having is that the "num" is not being called in the getSize method, and therefore not running the while loop, or at least that is what I believe is the issue.
import javax.swing.*;
public class getSize{
public static void main( String[] args )
{
int num;
num = Integer.parseInt (JOptionPane.showInputDialog ( "Please input a number" ));

I am trying to figure out stacks and queues and was trying to get this Palindrome program working so I could then play with it and use the Java visualizer site but for some reason the program isn't working correctly. It always states that the input is a palindrome no matter what the user input is.
The book that I got the code from is a little old so I changed a couple small things that I thought needed updating like adding scanner. I wanna use one with a custom array based stack and queue class rather than the java.util.Stack and Queue interface, just for understanding stacks and queues better hopefully.
import java.util.Scanner;
import javax.imageio.IIOException;
public class PalTest {
public static void main(String[]args) throws IIOException
{
Scanner scan = new Scanner(System.in);
PalindromeTesting x = new PalindromeTesting();

The program is to accept a string and display all the palindrome words(the words that are same even if they are reversed-------->mom,madam,malayalam etc.)in the string.
I need to solve this program urgently.
There are no syntax errors but after typing in the sentence,no output is displayed. This is my program....
import java.util.*;
class palindrome_test
{
public static void main(String args[])
{
Scanner in=new Scanner(System.in);
System.out.println("Enter a sentence");
String usersInput=in.nextLine();
[Code] .....
I am trying to create a program that reads a sentence, such as: "abba is running to the radar" scans this sentence, and then prints out all the palindromes. I am running into issues with my arrays and for statements. Here is my code:
static String palindrome, backwardsLower,
palindromeLower, palindromeClean, backwards2, backwards = "";
static String[] words;
static int counter;
public static void main(String[] args) {
palindrome = JOptionPane.showInputDialog("Please enter a phrase. " +
[Code] ...
I am aware that there is a few "useless" variables in there at the moment, I will clean them up (as well as some useless statements, I see those too). The issue comes at about line 17. The variable backwards REMOVES all the spaces from the array, so when it comes time to compare the strings, it is comparing individual words to the ENTIRE string, thus no words will ever be a palindrome.
I have to write a program that inputs a 5 digit integer from the keyboard and prints if the input number is a palindrome or not. I got it to work, but when my result prints it says "0 is a palindrome" or "0 is not a palindrome". How can I get rid of the 0 and replace it with the number input by the user?
import java.util.Scanner;
public class Palindrome {
public static void main(String[] args) {
int number;
int digit;
int temp;

this program used to implement palindrome String of using stack and queue.i wont to enter string by scanner how can i chang it ??????
class Palindrom_homwork1{
int top=-1;
int rear=-1;
int front=-1;
int max=3;
int max1=3;
char array[]=new char[max];
char array1[]=new char[max1];

I want to find the prime palindrome numbers less that a given number by my program. Here is my code, I am trying to find the method to solve the errors when I compile it. It said variable a might not have been initialized in line 41,62,86.

public class Lab5{
public static void main (String[] args){

We are making a tic tac toe game for my CS120 class and I am having trouble figuring out how to make our X's and O's. Is there a way to make shapes besides making two lines for an X and an oval with a white smaller oval inside to make an O? We have only learned the basics so far in class (i.e. events, inheritance, client-supplier, etc.)
These are our instructions:
Write a controller that controls the game. There is one human player (the X player) and the computer player (the O player). The name of the class must be TicTacToeController. In a sense, the controller is the game since the controller will 1) create a TicTacToeModel 2) create a TicTacToeView and 3) create a TicTacToeButton (you must write this class following the design pattern covered in class lectures), a label, and text field such that when the button is pushed, the player moves into the cell selected by the text field. After every player move, the computer moves into a randomly selected empty cell. When the game is over, a text message must be displayed somewhere on the screen the gives the status of the game. While you are free to change the appearance of the controller, the basic elements must be provided (a view of the game, a button, and a text field to enter the cell). A sample screenshot is displayed below.And this is the code i have thus far:
[import java.awt.*;
import javax.swing.JFrame;
public class TicTacToeView extends Rectangle
public TicTacToeView(int x, int y, int w, int h) {
super(50,60,w,h);
this.setBackground(Color.red);
JFrame win = new JFrame("Tic Tac Toe");
win.setBounds(10,10,w+100, h+100);
win.setLayout(null);
win.setVisible(true);
win.setBackground(Color.gray);

I am stuck. I was trying to make my own Color to use with awt.
I used the statement :
public static final Color purple = new Color(255,0,255);
When I try to use Color.purple it says it cannot reference purple.
I first learned how to program with BYOB. In BYOB there were variables and lists. Variables worked the same as Java and lists were groups of variables. To create a list, I would give it a name. I could then add variables to this list as items throughout the program. Here's an example of what a list would look like:
[[List]]
item 1: Hello
item 2: world
I could then call upon item 1 or item 2 and delete them if needed. In Java, I want to have 3 lists of variables into which I put user input as variables. The code would look something like the following: (stuff with "//" at the end is detailing what I want to do, not actual working code)
import java.util.*;
public class Archives {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);

I am currently in the progress of making a GUI for a project. I am trying to make a maze and I need it displayed in a GUI. So, I thought I would be able to do that with a text file that I created. The code I have for it so far runs and compiles but it is not displaying my text file as a GUI, even though it reads the file. All I get are a bunch of green rectangles. I am using Netbeans to code this
package rectangles;
import java.awt.Color;
import java.awt.Graphics;//this will draw the maze
import java.awt.Graphics2D;//
import java.io.BufferedReader;
import java.io.FileNotFoundException;//handles file

public static final String NAME="JAVATAR";
"final" makes sure the constant has the same value and prevents it from being changed. So why add "static" to make it a constant. I figured the reason a few weeks back but don't remember it now.
I've been learning Java in school for lika a year now. Our teacher wanted us to make a game called "Game of Life" .Now it's not very optimized because the only type of GUI we know how to make it with JButtons so if I want a 100x100 grid that means the program has to load 10000 buttons and change text and color on them which I can imagen cause lags and so on but if we ignore that lagg our teacher wanted us to make it loop-able and well I kinda succeeded but the only problem is that I can't get it to wait between every loop so if I tell the program to loop 100 times, the program processes that and that takes forever and then updates the board and sometimes it takes forever and sometimes you cant even see the "cells" moving. Is it possible to get my program to loop and if so how? Here is the code:

I want to know how can I make a JPanel slide to to another JPanel (Slowly move to the next). I've made multiple JPanels so when I click on next it will take me to the next panel. Now I just need to add a nice transition to make my program look nicer. Is there an easy way to do it? or any way is fine I just want to add a transition ....
