Write a Java program to check if number is palindrome comes from same category. Any one digit number including zero is always palindrome. Hope this gives you better understanding about the logic and program concept! Checking whether a number is palindrome or not is a classical Java homework exercise.

A palindrome is a word that reads the same backward or forward. It takes an InputStreamReader object as an argument.

Palindrome Program in Java

Using reverse is overkill because you don't need to generate an extra string, you just need to query the existing one. The following example checks the first and last characters are the same, and then walks further inside the string checking the results each time. It returns as soon as s is not a palindrome. The problem with the reverse approach is that it does all the work up front. It performs an expensive action on a string, then checks character by character until the strings are not equal and only then returns false if it is not a palindrome. If you are just comparing small strings all the time then this is fine, but if you want to defend yourself against bigger input then you should consider this algorithm. I am searching for the same palindrome solution but with character input. Also can I ask if the For loop is indeed checking each character from either half of the string and comparing them. Strip them from the string, and determine whether the string that remains is a palindrome. Take the answer for this smaller string java code for palindrome use it as the answer for the original string then repeat from 1. Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 on this site the. Would you like to answer one of these java code for palindrome. Not the answer you're looking for. Browse other questions tagged or.

For example, Palindrome Words : Level, Radar, Madam, Civic, Refer Palindrome Numbers : 12321, 171, 45854, 8427248, 1441 Palindrome Phrases : Never odd or even Was it a car or a cat I saw? It can also tokenize the underlying stream with the delimiter of your choice. We can check if given string is palindrome or not by reverse it and then compare it with original string. For example, we can compare the two words like this, orginalWord. Here is the snippet that does just that. Any one digit number including zero is always palindrome. If you miss this statement then, after completing the first line it will terminate. If you are looking answer of this question for interview purpose then better prepare a recursive version of palindrome program in Java as well because its common practice that programmer are expected to write java program using both recursion and iteration in Java. Hope this gives you better understanding about the logic and program concept!
