Java Palindrome Program – A blog to program a palindromic number generator in java.


In this program, we are going to share a Java Palindrome Program. You can also say that we will learn How to write a Java Palindrome Program.

Here, we are going to implement a java program that will check whether the number is palindrome or not.

A palindromic number is a number (in some base b) that is the same when written forwards or backwards. Most familiar palindromes are in base 10 and written using letters to stand for digits greater than 9, so 121 and 1001 are palindromic. The term “palindrome” was coined from the Greek roots palin (πάλιν; “again”) and dromos (δρóμος; “way, direction”), by English writer Ben Jonson in the 1600s.

Examples of numeric palindromes are:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9

11, 22, 33, 44, 55, 66, 77, 88, 99

101, 111, 121, 131…90909…98989…999

Here we have written a program to check whether a given number is palindromic or not. We have explained the program with comments.

Java Program To Check Palindrome Number. In This Java Tutorial We Will See How To Find A Number Is Palindrome Or Not In Java Programming Language Using Eclipse IDE. A Palindrome Number Is A Number That Is Equal To Its Reverse, Like 16461.

Java program to check if a number is palindrome or not – here we will discuss the various methods to check whether a given number is palindrome or not. In this problem we have to reverse the digits of an integer and add it to the original integer. If the sum of reverse and forward digit matches, then the number is a palindrome otherwise not a palindrome in java language!

This is one of the basic java programs which will help you in getting started with programming in java. It is an easy program, so you can use it for learning purpose as well.

There are many palindrome numbers which do not include any even digit at all, e.g., 121, 454, 677. It is quite easy to see that except for the number itself and its reverse, no other 3-digit palindromic number has this property. It can also be proved that there are no 2-digit or 4-digit palindromic numbers without any even digit. In fact there are only 10 such 5-digit palindromic numbers and only 8 more of them for 6-digit palindromes. No higher order numbers exist which have this property.

Let us now try to make a program to generate these numbers which do not contain any even digits at all. We will use the same method to find palindromes as we used in the previous program:

1) The first two digits will be 1 and 2 and the third digit will be between 0 and 9 inclusive, so that their sum is divisible by 11 (since 11 is a prime number).

2) The fourth digit will be a multiple of 5 (since 5 is a prime number) between 1 and 9 inclusive.

3) The fifth digit will again be chosen so that it is divisible by 11 (since 11

A palindrome is a word, phrase, number or sequence of words that reads the same backward as forward. Punctuation and spaces between the words or lettering is allowed.

An integer is said to be a palindromic number if its reverse is exactly same as the original one. For example, 545, 151, 34543, 343, 171, 48984 are the palindromic numbers. It can also be a string like LOL, MADAM etc.

In this example we will see how to check whether an integer (number) is palindrome or not and also check whether a string is palindrome or not using recursion.

We will see two programs to find the factorial of a number. The first program finds the factorial using a for loop and the second program calculates the factorial with recursion.

A palindrome is a word, phrase, verse, or sentence that reads the same backward or forward. Allowances may be made for adjustments to capital letters, punctuation, and word dividers. Famous examples include “Amore, Roma”, “A man, a plan, a canal: Panama” and “No ‘x’ in ‘Nixon’”.

Consider a given number, how to check if it’s a palindrome? For example 121 is a palindrome as reverse of 121 is also 121. While 123 is not a palindrome as its reverse 321 is not same as original number 123.

This program is based on the concept that we will extract each digits one by one till the number becomes 0. We will then compare the extracted digit with its corresponding digits in the number.
