JAVA. A palindrome is a word or a phrase that is the same when read both forward and backward.

java please. 

A palindrome is a word or a phrase that is the same when read both forward and backward. Examples are: "bob," "sees," or "never odd or even" (ignoring spaces). Write a program whose input is a word or phrase, and that outputs whether the input is a palindrome.

Ex: If the input is:

bob

the output is:

bob is a palindrome

Ex: If the input is:

bobby

the output is:

bobby is not a palindrome

Hint: Start by removing spaces. Then check if a string is equivalent to it's reverse.


Hint: Start by just handling single-word input, and submit for grading. Once passing single-word test cases, extend the program to handle phrases. If the input is a phrase, remove or ignore spaces.
