public boolean isPalindrome(String s){
for(int i = 0;i< s.length();i++ ) {
if(s.charAt(i)==s.reverse)
}
}
How to complete this to accomplish this goal?

@jgr208 That's not valid junit for anything I've ever seen... – JNYRanger Feb 09 '15 at 20:59

thought so, since i didnt see any assert true or anything like that – jgr208 Feb 09 '15 at 20:59

@jgr208 Not only that, but junit only allows for void return functions with no arguments. – JNYRanger Feb 09 '15 at 21:00

I think what you're trying to do is this?
public boolean isPalindrome(String s) {
for (int i = 0; i < s.length() / 2; i++) {
if (s.charAt(i) != s.charAt(s.length() - i - 1)) {
return false;
}
}
return true;
}
You can reverse strings using StringBuilder, so this could be more easy written as
public boolean isPalindrome(String s) {
return new StringBuilder(s).reverse().toString().equals(s);
}

1You use `StringBuilder` because it has a built in `reverse` method that will reverse the order of the String. And when reading the code, it is much easier to follow and understand what is happening. – Ascalonian Feb 10 '15 at 18:41
