How To Reverse A String In Java

Reverse a string in java is the most asked task in a java interview for beginners.
In this video, I am using a charAt() method of the 'String' class to reverse a string.
The charAt() method returns a character at a specified index.
So, the charAt() method accepts an argument of type integer, which is an 'index'. The index of the character we want as a return.
I have used a very simple logic in the program to get the reverse string. We are getting a character from the string in reverse order and adding it in another empty string.
Which means we will get the last character first and add it at the starting of an empty string.
Then we will get the second last character and add it to the second place in the new string and so on.
Finally, we will add the first character and of the string which we have to reverse, at the last place of the string which will be our reversed string i.e. our result.
We are using a simple for loop ion descending order to iterate over a string.
