Anyone Competent in Java?

[Granno]

Basically I have written this code:

/**

* Describe class Xmas here.

*

*

* Created: Thu Oct 13 18:04:31 2005

*

* @author <a href="mailto:">N. D. Measor</a>

* @version 1.0

*/

public final class Xmas {

/**

* Specifies the number of days of Xmas

*/

public static final int NUMDAYS = 12;

public static void main (String [] args) {

//loop through and get the days of Xmas verses,

// and print them to the console

for (int i=1;i<=NUMDAYS;i++){

getVerse(i);

}

}

/**

* Create and return a String of a whole i'th verse

* of the song

* (NOTE: A verse ends with a blank line.)

*

*/

public static String getVerse (int i){

for (int j=i; j>=1; j--) {

getLine(j);

}//for

if (i==1) {

System.out.println("A partridge in a pear tree.");

}//if

} //getVerse

/**

* Create and return a String of the i'th line of Xmas of the verse

*

* (NOTE: the repeating version of the first day of Xmas line is returned -

* "And a partridge in a pear tree.")

*

* e.g. sixth day of Xmas, "Six geese a-laying,"

*/

public static String getLine (int i) {

switch (i){

case 1: return ("And a partridge in a pear tree.");

case 2: return ("Two turtle doves,");

case 3: return ("Three French hens,");

case 4: return ("Four calling birds,");

case 5: return ("Five golden rings,");

case 6: return ("Six geese a-laying,");

case 7: return ("Seven swans a-swimming,");

case 8: return ("Eight maids a-milking,");

case 9: return ("Nine ladies dancing,");

case 10: return ("Ten lords a-leaping,");

case 11: return ("Eleven pipers piping");

case 12: return ("Twelve drummers drumming");

}

} // end of method getLine

/**

* Converts an int value into its related ordinal (as a String)

*

* e.g. convert 1 to "first"

*/

public static String toOrdinal (int i) {

switch (i) {

case 1: return ("first ");

case 2: return ("second ");

case 3: return ("third ");

case 4: return ("fourth ");

case 5: return ("fifth ");

case 6: return ("sixth ");

case 7: return ("seventh ");

case 8: return ("eighth ");

case 9: return ("ninth ");

case 10: return ("tenth ");

case 11: return ("eleventh ");

case 12: return ("twelfth ");

}

} // end of method toOrdinal

}

And the output i require is:

If anyone can help it would be fantastic. Apologies for the long post.

I can't help.

Do you have to break from them, or is that C++? Been a while since I really had a stab at anything much, need to get going on it again.

You can break from them, but return does the same job.

It's sorted now anyway, so if a mod wants to close it

Next time just PM SMuts directly - I taught him everything he doesn't know.

Anyone got any good advice on how to J-unit testing in JAVA i have absolutely no clue where to start with it.

any help would be much appreciated.

I've got a good guide somewhere...i'll try and dig it out. I'm working late most of this week so might be a few days before I can get it to you though (i need to find it!)...just PM me to remind me!

Also, whilst on the Java theme, I'm currently working on a small application which helps you manage your personal finances - its very much WIP but its useful if you have a few accounts and want to keep track of your outgoings - the aim also is to help with budgeting and track other expenses, like company expenses. I have it in Excel atm, but its difficult to maintain. If anyone's interested in testing it then give me PM and once its at a decent stage then ill send it across!

PS: Granno - what did you do to sort the issue out?

[Daggers]

Excel?

James LOVES Excel.

Cheers very much Hitesh. Will PM you over the weekend. Much appreciated buddy.

Granno, you're not at Sheff Uni are you? I remember do that exact task in one of my Java modules. Been out of the loop for a while now so probably wouldn't be as much use to you as others on here.
