How to use array in methods

package p1;

return (a[i]/2);
wats wrong in this?im new to java plz assist

public int evaluate(int a)
This is wrong (I think). Either pass an int or an
int[] (depending on what you want the method to do).
that's the exact problem. as I explained ages ago

How to use the POST method In Oracle APEX 3.1

Hi,
In APEX if we are submitting the page the parameters( Variables ) will pass through URL.
How to hide the these parameters from URL??
I Hope POST method will solve this problem.
How to use the POST method in APEX???
Help me out to solve this problem.
thanks in advance.
Cheers,
Shan

In APEX if we are submitting the page the parameters( Variables ) will pass through URL.No they won't. Submission POSTs the <tt>wwv_flow</tt> form.
Sometimes a branch may be performed after submission, generating a URL in which parameter values are visible. To avoid this, use the save state before branching option.
Other actions—like using navigation lists, or clicking a link in a report—will perform a GET using parameters in the URL. In these cases using Session State Protection is advised.

How to use ApplicationModule custom methods in JSP?

I have an ApplicationModule for which I have defined several custom methods (in the ApplicationModuleImpl class). I wish to invoke these methods from a JSP. I'm having trouble getting a scriptable reference to the application module object in the JSP. I can get data from the view objects using the jbo:xxx data tags, but I can't get any sort of reference to the application module object that would allow me to invoke the methods. I have tried editing the application module to expose the methods as client methods, but still can't get a reference to them.
My main questions:
1. Is there a way to invoke the custom methods somewhere between the jbo:ApplicationModule tag and the jbo:ReleasePageResources tag?
2. Is there a way to declare and use the application module without using the jbo:ApplicationModule tag? Would I ever benefit from doing this?

Alan, here's how to call a custom method String getSomeInfo() that I've created on my application module, MyModule in this example. Also, in this example the id parameter in the ApplicationModule tag is "am" (<jbo:ApplicationModule id="am"...):
First, edit your application module. In the app module editor, go to the Client Methods tab and move getSomeInfo into the selected list.
Next, edit your JSP to call your custom method.
<% MyModule myAm = (MyModule)am.useApplicationModule(); String someInfo = myAm.getSomeInfo(); %>
You also have to add the correct import statements to the page tag in your JSP:
<%@ page contentType="text/html;charset=windows-1252" import="oracle.jbo.*, MyModule.common.*"%>
Hope this helps

How to use array or type in "IN" criteria

Hi all,
anybody knows how to use group of same datatype data ( array or type ) in SQL statement
For example
ls_dept[1] = 'abc';
ls_dept[2] = 'xyz';
ls_dept[10] = 'ppr';
i want to use this group of data in "IN" criteria like
Select * from department where dept in ('abc','xyz'.....''ppr');
if anybody know how to use please reply me as soon as possible.
Thanks,

I hope you are not suggesting concatenating literals from a web front-end application ;) Is it not what he was saying.. he is getting user input info from an application.. if the user sends multiple values.. he has to build a string with concatenating literals..
correct me if I am wrong.

How i use bapi as method?

hi friends.....
i have BAPI........i want use that BAPI as METHOD for creating task or
how i use this that BAPI in my workflow template.
Thanks in advance,
bhaskar

You have to create a method on a business object, althoug in most cases this already exists in SAP,
so first check in SWO1 for the business object if this is already done.
If not, use, for instance method change of business object BUS2012 as a reference (go to swo1, type in bus2012, click display, position the cursor on the method change and click button program)
Kind regards, Rob Dielemans

How to use array?I am a newer ------:(

In C language I can use array this way:
char array[10][20];
fread(array[1],20,1,fp);
but in java,what to do?
char array[][]=new [10][20];
and the code below will cause an error:
binstream.read(array[1]);//error line
pls help me and tell me what to do,thank you very much

Hi evilstar007!
1st) There aren't unsigned primitives in Java, all primitives are signed.
2nd) The loop in previous message will read an entire line filling the buffer without length contraints. If there are n^z then it will read n^z "chars". This is is for text but I know there is a special one as you need, for bytes (primitive byte). You can also retrieve the bytes from stream:
data = new byte[dim];
inp.read(data);
I'm not sure about, there are a lot of methods and classes.
You pretend to read from stream and fill the contents of RomBanks array with length 32768L ok ?
Read the entire line and retrieve bytes.
Since you are a C programmer will be easy to understand Java.
Best Regards!

That doesn't do what you think it does, unless you want your array to contain 10 references to the same Point object.The OP has received a good answer, I believe. So it's worth risking diverting this thread into the weeds by pointing out that if Java had closures then BalusC's code could be modified to work.
