programes on strings

Have a look at the following link:

System.arrayCopy() method

import java.util.*;
public class CheckPalindrome{
    public static void main(String[]args){
    Scanner input=new Scanner(System.in);
    System.out.print("Enter String: ");
    String st=input.next();
    String str[]=st.split("");
    String reversedSt="";
    for(int i=str.length-1;i>=0;i--){
        reversedSt+=str[i];
    }
    if(st.equalsIgnoreCase(reversedSt)){
    System.out.println("String is palindrome");
    }
    else{
        System.out.println("String is not palindrome");
    }
    }
}
