Reverse a string in Java

0 votes
I have a "Hello World" kept in a String variable named hi. In order to print it in a reverse format, how could I do so? My understanding is that there is a function which is already inbuilt into Java that does the same. Could I please get help regarding this doubt?

To answer your question, you can use the following line of code:-

new StringBuilder(hi).reverse().toString()

The StringBuilder was added in Java 5. For the prior versions to Java 5, the StringBuffer class can be used instead which uses the same API.
