StringBuilder substring and reverse

IamtheWalrus

Can anyone write me a Java method that takes a substring of a string, reverses it and prints the outcome?

I'm guessing a StringBuilder is better than String but my issue is StringBuilder.substring() returns a String. To continue using StringBuilder I'd need to create a new StringBuilder object to do the StringBuilder.reverse() part.

Anyone a better solution to this?

public static void main(String[] args) {
    	StringBuilder sb = new StringBuilder("abcdefgh");
    	
    	sb = new StringBuilder(sb.subSequence(2, 5));
    	
    	sb.reverse(); 
    	System.out.println(sb.toString());
    }

Thanks. I used StringBuilder: subSequence and reverse.

Huh, isn't that what you had in your OP?

It was for a test and the test turned out to be different. I sas asked to turn hannah into nahhan. So I just needed subsequence and append.
