Palindrome- Find string is palindrome or not in java


In this core java programming tutorial we will write a program to find Palindrome- Find string is palindrome or not in java.



Q.What is palindrome?
A. If reverse of string is same as original one, than our string is palindrome or palindrome is a string which reads the same backward or forward.

Example in java>
input String : aabaa
output: it’s palindrome.




time complexity - will be O(n/2)

public class PalindromeExample {
   public static void main(String...args){
      String inputString="aabaa"; //String to be reversed   
      System.out.println(isPalindrome(inputString) ? inputString+ " is a palindrome." :  inputString+ "is not a palindrome.");   
   }
  
   /*
   * returns true if inputString is palindrome.
   */
   public static boolean isPalindrome(String inputString){
      char ar[]=inputString.toCharArray();
      for(int i=0,j=ar.length-1; i<(ar.length/2); i++,j--){
             if(ar[i]!=ar[j])
                   return false;
      }
      return true;
   }
}
/*OUTPUT
aabaa is a palindrome.
*/


So in this core java programming tutorial we wrote a program to - find Palindrome- Find string is palindrome or not in java.
