Questionproblem in implementing isPalindrome() by using java collections.reverse Pin
ElenaRez12-Mar-18 10:41
memberElenaRez12-Mar-18 10:41 
Hi I wrote a method for determining whether an integer is a palindrome like below. and for the input number -2147483648 I get true as it's output but in reality the output should be false. It seems the Collections.reverse(list) in my method doesn't work, I mean it doesn't reverse the input. I appreciate if someone can help my problem.

<pre> public boolean isPalindrome(int x) {
	        String raw=String.valueOf(x);
	        if(raw.charAt(0)=='-')
	            raw=raw.substring(1);
	        List<Character> list = new ArrayList<Character>();
	        for(char c:raw.toCharArray())
	            list.add(c);
	          List temp=list;
	         
	        	  Collections.reverse(list);
	       
	        return temp.equals(list);
	    }
