PalindromeTest using Java

PalindromeTest

PalindromeTest using Java I created the Palindrome Function using Java. Declare the beginning, middle, and end index of the input parameter. Compares the start and end values, if they are the same, return true, if they are not, return false. Use the toUpperCase method to distinguish between uppercase and lowercase letters.

Source Code

  public class PalindromeTest {
  static boolean isPalindrome(String input) {
	    boolean result;
	    int length  = input.length();
	    int i, begin, end, middle;
	    begin  = 0;
	    end    = length - 1;
	    middle = (begin + end)/2;
    for (i = begin; i <= middle; i++) {
    	
      if (Character.toUpperCase(input.charAt(begin)) == Character.toUpperCase(input.charAt(end))) {
    	  
        begin++;
        end--;
      }
      else {
        break;
      }
    }
    
    if (i == middle + 1) {
    	result = true;
    } else {
    	result = false;
    } 	
	
	
	return result;
}

}

input

public static void main(String[] args) {
	System.out.println(isPalindrome("civic"));
	System.out.println(isPalindrome("abc"));
	System.out.println(isPalindrome("Anna")); 
	System.out.println(isPalindrome("Civic")); 
	System.out.println(isPalindrome("Kayak")); 
	System.out.println(isPalindrome("Level")); 
	System.out.println(isPalindrome("Madam")); 
	System.out.println(isPalindrome("Mom")); 
	System.out.println(isPalindrome("Noon")); 
	System.out.println(isPalindrome("Racecar")); 
	System.out.println(isPalindrome("Radar")); 
	System.out.println(isPalindrome("Redder")); 
	System.out.println(isPalindrome("Refer")); 
	System.out.println(isPalindrome("Repaper")); 
	System.out.println(isPalindrome("Rotator")); 
	System.out.println(isPalindrome("Rotor")); 
	System.out.println(isPalindrome("Sagas")); 
	System.out.println(isPalindrome("Solos")); 
	System.out.println(isPalindrome("Stats")); 
	System.out.println(isPalindrome("Tenet"));
