Java

Write the methods with the following headers Return the reversal of an integer, i.e., reverse(456) returns 654 public static mt reverse(int number) Return true if number is a palindrome public static boolean isPalindrome(int number) Use the reverse method to implement isPalindrome. A number is a palindrome if its reversal is the same as itself. Write a test program that prompts the user to enter an integer and reports whether the integer is a palindrome. Hint: you can find the reverse of a number by one of the following two techniques: . Convert your number into a string, then reverse the string?s characters in a for loop using string concatenation and charAt() method. . Use the and % operators with a divisor equal to 10 in order to extract the individual digits and then combine these digits in a reverse order mathematically or by string concatenation.

Explanation / Answer

public static int reverse(int number){
   int result = 0,digit;
   while(number > 0){
       digit = number % 10;
       result = result*10 + digit;
       number = number /10;
   }
   return result;
}

public static boolean isPalindrome(int number){
   return number == reverse(number);
}
