A Java program to reverse a string. We are using 'getByets()' method of the String class to get byte array of the specified string and assign it to the another byte array of the same length in the descending order. New String object of the reversed byte array will give reversed string. The program is embedded at https://coderolls.com/reverse-a-s…
