Palindrome program in Java - Here, we will discuss the various methods to check whether a given number is a palindrome or not. A compiler is added so that you can execute the program yourself, alongside various examples and sample outputs are given. The methods aforementioned are: Java Program To Convert Octal To Hexadecimal | Vice Vers Java program to check if a string is a palindrome or not, it's a palindrome if it remains the same on reversal. For example, dad is a palindrome, as its reverse is dad, whereas program isn't, as its reverse is margorp that is different from program. Some palindrome strings examples are: j, mom, madam, ab1ba, 12321

Palindrome Program In Java - 5 Ways Program

Introduction to Palindrome in Java The word palindrome has a Greek origin, a word, number, or set of characters that reads the same forward and backwards. Some examples of a palindrome are MALAYALAM, 343, 2001002, etc. Palindrome in Java can be implemented using many ways. Here we will discuss some important ways Below is Palindrome logic in Java: Fetch the input number that needs to be checked for being a Palindrome Copy number into a temporary variable and reverse it. Compare the reversed and original number Introduction to Palindrome in Java A String or a number is said to be a palindrome if it remains the same even after it is reversed. For example, 'MADAM' is a palindrome string since it is spelled 'MADAM' even if it is reversed. But in the case of 'LUCKY', this string is not palindrome as it is 'YKCUL' when it is reversed This Java program asks the user to provide a string input and checks it for the Palindrome String. Scanner class and its function nextLine () is used to obtain the input, and println () function is used to print on the screen. Scanner class is a part of java.util package, so we required to import this package in our Java program Java program to check palindrome (using library methods) 05, May 17.
