Write a Java program to check if given String is palindrome or not

Below program illustrates if given String is palindrome or not in Java:

public class PalindromeString {
 
	public static void main(String[] args) {
		String str = "MADAM";
		boolean isPalindrome = checkIfStringIsPalindrome(str);
		if(isPalindrome) {
			System.out.println(str + " is Palindrome!!");
		} else {
			System.out.println(str + " is not Palindrome!!");
		}
		
	}
	
	private static boolean checkIfStringIsPalindrome(String str) {
		char[] chars = str.toCharArray();
		int len = str.length();
		for(int i=0, j=len-1; i<len/2; i++,j--) {
			if(chars[i] != chars[j]) {
				return false;
			}
		}
		return true;
	}
}
