How to Reverse a String in Java?
To reverse a string in Java, you can use several methods. One common approach is to convert the string into a character array, then iterate over the array and swap the characters from the beginning to the end. Another way is to use the StringBuilder class, which provides a reverse() method that can be applied to the string. Additionally, you can use the StringBuffer class, which is similar to StringBuilder but is thread-safe.
Whichever method you choose, make sure to handle null or empty strings appropriately and test your code thoroughly to ensure that it works as expected. Reversing a string may seem like a simple task, but it requires attention to detail and careful implementation to avoid errors.
The following example code shows a few approaches to reverse a String :
