Palindrome Number Example in Java 

for the java palindrome example shown in the yellow box at the top, how do you make it so, once it reverses the number once, you add the reversed number with its original number, and if that sum is still not a palindrome, how do you reverse that sum again?

that my code....pleese i need help in my while and do....

import apcslib.*;
import chn.util.*;

public class Palindrome
{
String sentence;
String reverse;

public Palindrome ()
{
sentence ="";
reverse ="";
}
public void start()
{
getInput ();
reverseInput ();
compareSens ();
}
public void getInput()
{
System.out.println("Welcome To PALINDROME");
ConsoleIO console = new ConsoleIO();
System.out.print("Please enter your sentence ");
sentence = console.readLine();
sentence = sentence.toLowerCase();
System.out.println("Your sentence is " + sentence);
}

public void reverseInput ()
{
String temp = sentence.trim();
System.out.println("Your trim sentence is "+ temp);
int senLength=temp.length();
System.out.println("Length of the sentence is "+ senLength);
int n = temp.indexOf(" ");
System.out.println("The first white space is at "+n);
while (senLength>0)
{
temp=temp=temp.substring(0,n);
temp=temp.substring(n+1,temp.length());
System.out.println("The second white space is at " + temp);
reverse=reverse+sentence.charAt(senLength-1);
senLength--;
}
System.out.println("The reverse is " + reverse);
}
public void compareSens ()
{
if (sentence.equals(reverse))
System.out.println("The sentence is a palindrome");
else
System.out.println("The sentence is not a palindrome");
}
}

i need help of my prg in palindrome
class Palindrome
{
public static void main(String[] args) throws IOException
{
String str[]=new String[1];
String dest[]=new String[1];
int j=0;
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
System.out.println("Enter the String to Palindrome");
int i=str.length;
for(i=(i-1);i>=0;i--)
{
str[i]=br.readLine();
dest[j]=str[i];
j++;
}
//if(dest.compareTo(str)==0)
if(str.equals(dest))
{
System.out.println("String are Palindroome");
}
else
{
System.out.println("not palindrome");
}
}
}

plz correct the program
thanks in adv

your for-loop is astonishing...
do you realize what are you doing there?

Why we are using Integer.parseInt()method

Would it not be easier to store the line input into a string, then parsing the string into an integer, then parsing the reversed string into a separate integer variable and comparing them?

Java Program for palindrome

Posted by Dhanush on Sunday, 08.5.07 @ 14:51pm | #22705

I tried to run this code but it won't work on zeros.. it converts the zeros to one....
