Frequently Asked Java Program 05 Palindrome String How To Check Given String Is Palindrome Or Not

Palindrome String Check Program In Java Basic Java Program In this article, we will learn how to check if a string is a palindrome in java. so let us consider a string “str”, now the task is just to find out with its reverse string is the same as it is. example of palindrome: input: str = “abba”. output: yes. input: str = “geeks”. output: no. Return false; } } } } if the string is made of no letters or just one letter, it is a palindrome. otherwise, compare the first and last letters of the string. if the first and last letters differ, then the string is not a palindrome. otherwise, the first and last letters are the same.

Frequently Asked Java Program 05 Palindrome String How Palindrome string check program in java. 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. First approach. to check palindrome, we can pick the characters (one by one) from start and end of string and start comparing to each other. pick first character and last character of string and compare. if both matches – continue. else string is not palindrome. pick second character from start and last, compare both. Recursion is a very popular method to solve these kinds of problems. in the example demonstrated we recursively iterate the given string and test to find out whether it’s a palindrome or not: public boolean ispalindromerecursive(string text) {. string clean = text.replaceall( "\\s ", "" ).tolowercase();. Method 2: check palindrome string using for loop (naive approach) java also allows us to use loops to check if a string is palindrome or not. for instance, in the following code, we create a user defined “checkpalindrome()” method that uses a for loop to check if the given string is palindrome or not:.

Output 1: enter a string to check if it is a palindrome: aabbaa. input string is a palindrome. output 2: enter a string to check if it is a palindrome: aaabbb. input string is not a palindrome. if you wanna use while loop in above program then replace the for loop with this code:. In this program, we need to check whether a given string is palindrome or not. a string is said to be palindrome if it is the same from both the ends. for e.g. above string is a palindrome because if we try to read it from backward, it is same as forward. one of the approach to check this is iterate through the string till middle of string and.
