Hi friend,


Example to check the number is a palindrome

import java.io.*;

public class PalindromeExample {
public static void main(String [] args){
try{
BufferedReader br = new BufferedReader(
new InputStreamReader(System.in));
System.out.println("Enter nober");
int no= Integer.parseInt(br.readLine());
int n = no;
int rev=0;
System.out.println("Number: ");
System.out.println(" "+ no);
for (int i=0; i<=no; i++){
int r=no%10;
no=no/10;
rev=rev*10+r;
i=0;
}
System.out.println("After reversing the number: "+ " ");
System.out.println(" "+ rev);
if(n == rev){
System.out.print("Number is palindrome!");
}
else{
System.out.println("Number is not palindrome!");
}
}
catch(Exception e){
System.out.println("Out of range!");
}
}
}


Thanks

For String :

public class Palindrome {
public static void main(String[] args) {
String str1 = "eye", str2 = "bye";
System.out.println("Palindrome detection");
System.out.println(str1 + " "
+ isPalindrome(str1));
System.out.println(str2 + " "
+ isPalindrome(str2));
}
static boolean isPalindrome(String s) {
int left = 0;
int right = s.length() - 1;
while (left < right) {
if (s.charAt(left) != s.charAt(right))
return false;
left++;
right--;
}
return true;
}
}
