Java library provides StringBuffer and StringBuilder class with reverse method which can be used to reverse String in Java. The method below shows you how to reverse the String, which you can further reuse to check if given String is Palindrome or not.
Since reverse is a recursive job, you can use recursion as well as a loop to reverse String in Java. How to Reverse String in Java Using Iteration and Recursion - Example How to reverse string in java is popular core java interview question and asked on all levels from junior to senior java programming job.
This example will help you to prepare better for using recursion in java which is often a weak area of Java programmer and exposed during a programming interview. Now if you succeed in writing String reverse function, an iterative version without using StringBuffer reverse than they finally ask you to write a recursive one.
You can also check How to reverse String with recursion in Java if you want to see the recursive code. By looping through character array and appending it into empty String we can get reversed String in Java, as shown in the following example.
As I said recursive solution is always tricky to come up you need to found a suitable base case and than repetitive call recursive method with each call reducing length of argument. After initial input validation, we are just iterating through String, starting from end to start and generating a reverse String.
In this tutorial we will see how to reverse string in both iterative and recursive fashion. At the same time, Writing Java program to reverse String in Java without StringBuffer is one of the popular Java String interview questionwhich requires you to reverse String by applying logic and by not using API methods.
Reverse String in Java using Iteration and Recursion if you are from C background and new to Java then you get surprise that java Strings are not character array instead they are object and Strings in Java are not null terminated but still you can use your C skill to write iterative reverse function for string by getting character array by calling String.
In the main methodwe have first used StringBuffer and StringBuilder to reverse contents of String and then we wrote our own logic to reverse String.How do I get Java code for reverse a string using recursion? How can I write a program in Java to reverse an array using recursion using 2 parameters 1 being the array and the other an integer?
How do I write a program to find the first non-recurring character of a string using recursion? Write a program to reverse a string using recursive algorithm.

C++ program to Reverse a Sentence Using Recursion This program takes a sentence from user and reverses that sentence using recursion. This program does not use string to.
Java Algorithms. Java - Numerical Problems Java - Combinatorial Problems C Program to Reverse the String using Recursion “program” will be reversed to “margorp” Here is the source code of the C program to reverse a string. The C Program is successfully compiled and run on a Linux system. The program output is also shown below.
Write a java program to reverse a string? This is one of the most frequently asked java program in the technical round of java fresher’s interview. Interviewer may ask you to write different ways to reverse a string or he may ask you to reverse a string without using in-built methods or he may ask you to reverse a string using recursion.Download
