Write a java program to reverse a string using recursion

Reverse words in a string using recursion

But, StringBuilder is preferred as it is not synchronized and is faster than StringBuffer. Finally, I called the reverse method as r. Though StringBuilder class has a reverse method which can do the reversal of the string but generally in the interviews it will be asked to write the iterative or recursive logic or both so in this post both ways are given. Here, I have used the CharAt method in order to extract the characters from the input String. String Reverse using Recursion Recursion is nothing but a function that calls itself. Then, I have appended them in reverse order to reverse the given String. If you have any doubt or any suggestions to make please drop a comment. Reversing a string in Java - Non-recursive Non-recursive solution follows the logic of starting from the end of the String and keep moving back character by character and keep appending those characters to form a new string which is reverse of the given String. This brings us to the end of the article on Reverse a String in Java. It is one of the simple approaches to reverse a String in Java. After that, I have just iterated the given array in the reverse order. Reverse a String using CharAt Method In the below given Java program will help you to understand how to reverse a String entered by the user.

Here, I have used the CharAt method in order to extract the characters from the input String. But, StringBuilder is preferred as it is not synchronized and is faster than StringBuffer.

In this approach, I will write a method which reverses the String by calling itself recursively.

The main task of the CharAt method is to return the character at the specified index in the given String. Reverse a String using CharAt Method In the below given Java program will help you to understand how to reverse a String entered by the user. I hope you found it informative.

Then, I have read the entered String using sc.

We are here to help you with every step on your journey, for becoming a besides this java interview questions, we come up with a curriculum which is designed for students and professionals who want to be a Java Developer. But, StringBuilder is preferred as it is not synchronized and is faster than StringBuffer. Friday, 5 January How to Reverse a String in Java Writing a Java program to reverse a string using a recursive method or using iteration is one Java interview coding question asked quite frequently along with some other popular questions like How to find the longest palindrome in a given String , How to find all the permutations of a given String. I hope you found it informative. Then, I have read the entered String using sc. Recursive is a little hard to visualize so let's see how recursive calls will actually stack up. This brings us to the end of the article on Reverse a String in Java. Got a question for us? Reversing a string in Java - Recursive In recursive solution, in each recursive call to the method you take the first character index 0 and call the method with the rest of the string excluding the first char and add the first char of the passed String at the end. Finally, I called the reverse method as r. The main task of the CharAt method is to return the character at the specified index in the given String.

After that, I have just iterated the given array in the reverse order.
