Hii ishant,in your function ispalindrome,you have to do s=s+str.charAt(i) as it will store the str string in s otherwise it is only storing the last character in s,and in the loop put condition i>=0 also to take the first character of the string,also print the answer you have returned.

this is your edited code for help
