How do you return more than one value from a method?

say I have this:
public static int myFunc(String inString)
// I want to return two values from this method
}yeah so how would i do that?

If the two values are somehow related--like a person's name and his age--define a class that has those two values as member variables--for example, Person. But only if that class and the assocation of those two quantities makes sense as an entity in your program. Don't do it just to jam to quantities into one return.
Or, if the two values are two of the same thing--person A's age and person B's age--then you can return an array or Collection.
If it doesn't fit either of those two scenarios, then your method is trying to do too much unrelated stuff and you should break it into multiple methods. For example, calculating a Person's age based on his birthdate and today's date and calculating his Body Mass Index based on his height and weight. Those two quantities should NOT be returned together.

How to return more than one value from a function

hello everybody,
Can anyone tell me how to return more than a single value from a function, the problem is i have 4 points,
2 points form one line ,another 2 points form 2nd line ,each point is 3 dimensional(x,y,z coorinates) so i will pass these values to func(x1,y1,z1,x2,y2,z2,x3,y3,z3,x4,y4,z4), i will find the point of intersecton of two lines and i will get it as x,y,z , now how to return these 3 coordinates,usually the function returns only one value, please help me to solve it out.
Thanks.

I think the easiest way or trick here is (easiest isn't always the best as we know, but atleast this one will work) to create simple data array. and pass that. Create an array with:
<code>
class justArray {
int x=0
int y=0;
int z= 0;
...somewhere
justArray[] points= new justArray[4];
points[0].x= ..
points[0].y= ..
points[0].z= ..
points[1].x= ..
return points[]
</code>

How to return more than one varibles from a method?

can you use the codes:
return var1, var2,var3;
If not, what is the correct way to do so? thanks.

You can only return 1 object from a method in Java.
However, this 1 object can contain multiple other objects. For example, a Vector object:
public Vector someMethod() {
    Vector v = new Vector();
    v.add("abc");
    v.add("xyz");
    v.add("123");
    return v;
}If these multiple objects are the same type, you can also use array to achieve want you want.
public String[] someMethod() {
    String ss = new String[3];
    ss[0] = "abc";
    ss[1] = "xyz";
    ss[2] = "123";
    return ss;
}--lichu

How do you delete more than one item from download folder at a time?

I have been trying to clean out my downloads folder which has gotten too full. Mostly audiobooks which are now in iTunes and photographs that I have received from family and friends. I can drag them one at a time into the trash, but was hoping there is a faster way. If not, I will do this slowly. My understanding is that if the file is saved somewhere else, deleting it from the downloads folder doesn't delete it from my mac, right?
Thanks,
Laverne's Mom

One more question, am I correct in assuming that if I delete something from the downloads folder, even an application I have downloaded (I have a program that converts photos to cross stitch patterns and I don't want to delete it) that the application will not be deleted from my computer?
Laverne's Mom
That is probably a correct assumption. However it's always a good idea to double check before trashing something. Let's use the App (that's what programs are called on Macs) for cross stitch patterns. Check the Applications folder and if you see the app there it's fine to trash it from your downloads folder. Even if you goof once it's in the trash you can get it out of the trash assuming you haven't emptied the trash. Open the trash folder, right click the item and select Put Back. If you are not using Snow Leopard (10.6.x) then you can drag the item back to where it was originally.

How do you burn more than one song from my Logic on to a CD?

I have like five songs done that I want to burn on one CD at one time. When I bounce a song I seem to only burn one song. Thanks for the help

Hi,
bounce the songs to iTunes, create a playlist and burn the CD with iTunes. Nice, smooth workaround for Logic Express users.
You could also use third party burn software (free or expensive)
But if you want to spend some money, i suggest upgrading to Logic Studio, which contains Waveburner.

}Is it possible to have test() return more than one value? And if it can, can you post an example showing how?

Could you post an example of how to do this?If you do not know how to define a class, you need to start from the very beginning.

Can Function Return more than One Values ??

Hi Experts,
I would like to ask you Can Function Return more than one values. I Used Function with Out and In out parameter and its working Fine..
1. what is harm using Out and In out parameter in function
2. if we can use Out and In out parameter in Function so what is deffernce between procedure and Function.
3. Is there any Other Way Though which we can return more the One values in Function.
Please advice me...
Thanks
Umesh Goel

Yes/No.
You can return multiple value from function. But, in PL/SQL and not in a SQL.

Can a method return more than one value?

I was studying for my biology exam and I got bored and I started thinking and then I wandered if a method can return more than one value...?
For example, if I want a method to return a row a column, I make a method that returns an int. But what if I want to return two ints? Or what If I want to return an integer and a string? Is it possible or do I have make two methods, each returning one thing?
What I always did until now is is I want for example to return a few integers, I would store them in a String and then when I return the string, I parse the numbers out using stringtokenizer... but it doesn't look like the best way... and it's pretty annoying...

I'm weak on terminology, hence I don't even know what
AFAIK means...As Far As I Know
This doesn't really make sense for me. It's more
efficient to make a whole class just for two
integers, than having two methods? Efficiency is not the point. The flow is.
If you have two methods, the caller must be aware of both of them. The other way it's up to the callee.
Just because the
two integers are related to each other? Doesn't
making a class require more memory usage than just
making two one-line methods?The memory usage is not wholly irrelevant, but there are ways to handle that (caching, inlining, etc.).
It's a bit hard to counter your point for me, but if you had done a lot of GUI painting stuff, you'd see all those Points, Dimensions, Rectangles, you name it, are quite invaluable.

Can oracle function return more than one value

Hi All
please answer can oracle function return more than one value
need one schenario
regards

Can any function, irrespective of the language, return multiple values?
OF COURSE NOT!!
So why do you think Oracle will now suddenly do it differently than all other languages? Never mind that it is impossible for a function (a unit/module of code) returning a memory address, to return multiple memory addresses. The machine code that does that, has not been yet been designed/implemented.
I am continually amazed that this question is asked. It is about something so fundamental in almost every single 3rd and 4th generation language... something that is taught right at the start... the definition of what a procedure and what a function is.
Sorry, but I simply cannot pull punches on this subject and smooth it over. There is something fundamentally wrong with your training as a programmer if you have to ask such a question about a function.
And whatever programming skills you build on such a foundation, will be seriously lacking.
I kindly suggest that you get back to the very basics of programming - and review and revisit until you fully understand it. There are no shortcuts in becomming a good programmer.

How do you add more than one song to library.....

How do you add more than one song to the library using the "Add File to Library" option? I just upgraded to itunes 7.1.1.5 from an early version and used to be able to do this but now it want let me, it only lets me add one song at a time. I don't want to use the "Add Folder" option because it adds m3u playists and all kinds of things I don't want to be in my library. Is this a glitch? because it doesn't make sense.

When using the "add file to library" feature, hold down the CNTL (control) button as you pick your songs...
DON'T RELEASE THE BUTTON UNTIL YOU HAVE SLECTED ALL THE SONGS...
then just hit hit the button to add them a voila
