Check string for palindrome

Question

A palindrome is a word, phrase, number or other sequence of units that can be read the same way in either direction.

To check whether a word is a palindrome I get th

Answer 1

And here a complete Java 8 streaming solution. An IntStream provides all indexes til strings half length and then a comparision from the start and from the end is done.

public static void main(String[] args) {
    for (String testStr : Arrays.asList("testset", "none", "andna", "haah", "habh", "haaah")) {
        System.out.println("testing " + testStr + " is palindrome=" + isPalindrome(testStr));
    }
}

public static boolean isPalindrome(String str) {
    return IntStream.range(0, str.length() / 2)
            .noneMatch(i -> str.charAt(i) != str.charAt(str.length() - i - 1));
}

Output is:

testing testset is palindrome=true
testing none is palindrome=false
testing andna is palindrome=true
testing haah is palindrome=true
testing habh is palindrome=false
testing haaah is palindrome=true
