Note: If you use StringBuilder then you can use it's reverse method to reverse the string. It does not make sense to create StringBuilder object to just append small String. Even interviewer may ask you reverse a string without using any built-in reverse methods or additional classes like StringBuilder or StringBuffer. Use StringBuilder for concatenating or appending long strings. This can be a most efficient way to reverse a string in Java without build-in method

@prof.mangabhai 7 месяцев назад

in a interview this wouldn't be satisfactory, since everytime we are making a new string when concating a new character, so for super large strings it is not advised to use this method, use a stringbuilder or a char[] (which can be later converted to string by toString() method)

Little modification: we can use stringbuilder instead of concatenation. Thanks for your videos!! 😊

Is this a better way to use: `i >= input.length / 2` and each iteration swap first and last chars?

Use StringBuilder with append instead of result = result + i-value

You've chosen the most inefficient approach. Delete the video and think of what you have done.

You show me efficient approach

@@JavaGuides May be we can use Stringbuffer to append the character. But this way is also fine.

@@JavaGuidesSwap characters from both halves of the string from the ends to the middle. It was among the comments.
