Reverse a String in Java

This Java program uses the StringBuilder class to reverse a given string.

  • The original string is initialized as "Tutor Joes Computer Education"., and it is printed using System.out.println(a).
  • Next, a new StringBuilder object b. is created, and a for loop is used to iterate through the characters of the original string from the end to the beginning (i=a.length()-1;i>=0;i--.).
  • The charAt(). method is used to get each character at the current index, and it is appended to the new StringBuilder object b. using the append(). method.
  • Finally, the reversed string is printed using System.out.println(b) .
