Java statement to reverse paragraph?

This is very easy, this is vb.net, you can look for similar functions in java

'// this line copies/convert the text to character array
Dim characters() As Char = txt1.Text.ToCharArray

'// Reverse the array
Array.Reverse(characters)

'// convert it back to string
txt1.Text = CStr(characters)

enjoy

Goal is to write a program that will reverse each sentence a user enters. Upon reversing the paragraph, it will capitalize the first letter after each period separating the sentences and also delete any period that starts the new paragraph.

If I interpreted your problem statement correctly,

My name is Sayo. I am a student.

should give

.tneduts a ma I .oyaS si eman yM

after reversal, capitalize the first letter after each period separating the sentences, giving

.tneduts a ma I .OyaS si eman yM

(the period after the last "t" in students did not separate sentenses so I'm assuming it will not be capitalized), afterwards, delete the period that starts the new paragraph (which is only the first period after reversal), resulting in

tneduts a ma I .OyaS si eman yM

Am I right?

The code is attached to this reply. Download it and change the extension from jpg to html.

I don't like the way nairaland handles the presentation of "[ccode] [/ccode]". You may want to check out how javaranch.com handles it.
@omo_to_dun how were you able to trick nairaland into rendering your code perfectly? I'm surprised HTML formatting is not working here. Or, am I missing something?

Please attach it to your next comment. Thanks

Sorry it took me this long to reply, I have been out of town since Friday. A big thank you to everyone who responded and offered to help out, i really appreciate it.
@SayoMarvel Thanks a great deal, I will look at the code in a minute and give you feed back on it, thanks once again

@SayoMarvel So i realized you wrote that in Javascript?? or some other java coding i'm not familiar with. I'm a newbie and this is more like an introductory class so how can I change it to the regular java that i know? Like the one i posted in my first post?

Its regular java. I just exported it to html (because I thought it will improve the way nairaland renders the code). And those funny things you saw there are javadoc coments (and tags). Ok, here is a plaint version with no effizy.

public class Reverser {

    public static void main(String[] args) {
        java.util.Scanner scanner = new java.util.Scanner(System.in);
        System.out.println("Welcome. Please type your paragraph and hit the "
                + "\"Enter\" key when you are done.";

        //fetch your input.
        StringBuilder sb = new StringBuilder(scanner.nextLine().trim());

        //reverse the string/
        sb.reverse();

        //please note that the local variable [i]index [/i]is initially
        //being set to 1 instead of 0. In cases where the paragraph ends with a
        //period, such a period does not separate sentenses so the the character
        //before it should not be capitalized.
        int index = 1;

        //search for all periods.
        while(true) {
            index = sb.indexOf(".", index);
            if (index < 0)
                break;

            //convert the character following the period to its upper case.
            sb.replace(index + 1, index + 2, String.valueOf(sb.charAt(index + 1)).toUpperCase());

            //increment your index so that you won't keep catching the same
            //period over and over.
            index++;
        }

        //delete the period that starts the new paragraph,
        //obviously this is the first period.
        if (sb.charAt(0) == '.')
            sb.deleteCharAt(0);

        System.out.println(sb);
    }
}

OH i thought as much, it was confusing. And you just saved me some painstaking hours trying to figure this out, i have been refreshing NL ever since my last post lol. there ain't no method or class I haven't tried yet, I just don't know how to execute them to fit this program. Thank you so much for that, i really appreciate your help. I should probably have stayed with my Computer Science instead of IS where you basically don't get to learn the classes in detail.

At @OP are you talking reversing words or just the entire paragraph?

If its the entire paragraph all you need is just to call the String.reverse method

@Mobinga u're hard to reach i have gone far in the xchange game stuff. just wanted some advice from you. my mail is okeowoaderemi@gmail.com. hows life ?
