Finding the average of all the values stored in a two dimentional array
public int avg(int[][] numbers2){
int sum = 0;
float avg = 0;
for(int r = 0; r < numbers2.length; r++)
for(int c = 0; c < numbers2[r].length; c++){
sum += numbers2[r][c];
}So I have this code that of course finds the sum of all the values stored in the array int[][] numbers. What I am having an issue with is finding the average of the numbers. When I attempt to use:
avg = sum / numbers2.length; I get the sum / 3 because my array looks like:
int[][] numbers2 = {{1, 2, 3},
{4, 5, 6},
{7, 8, 9}
};Any ideas on what I should do or where I could find information on this process?
2 dimensional arrays have 2 lengths:
myArray.length and myArray[0].length
The first one I believe is fixed, the second one may vary from row to row. But if you know that it won't vary, then you can just use the [0] row length.

How/where to get the values stored in these two structure fields?
hi
need your help to find out where the following two fields get stored in tables...or is there any fm or bapi to get the data stored in these two fields?
1) Create Scheduling agreement:
Tcode: ME31L
Field label - Agreement type
Field name - EVART
Structure - RM06E
2) Purchase order display:
Tcode: ME23
Provide any Purchase order craeted already (where release strategy is implemented)
Select the line item & click release strategy icon at the top.
You will find a new pop-up menu. In that place the cursor on the startegy code like
Final release or XX or etc.
Field name - ANZEF

How to find out the type of the value stored in a string variable?

I have a string variable str, in which the following type of values wil be stored
1) Intger
2) Long
3) boolean
4) Char
Is there any method to find out the type of the value, anything like str.getType()?. Please kindly help me. Thanks in advance.Hi All, i'm sorry for the double posting, by mistake it occured.
Thanks for your replies, i have a string variable str, in which the value is stored and i have another string variable type, in which the type of the value is stored.
For example,
String str = "15";
String type = "Integer";
Is there any way to verify whether the value stroed in str is of type stored in the variable 'type'. I want to write a method of type boolean, it will throw true of the value stored in str is of type 'type'. Thanks -
How can i find the value category code in CJVC
Hi Gurus
how can i find the value category code in CJVC and which tables its stored.can any one tell me.please pleaseRead TPIK3 in an internal table, then search COEP-KSTAR in this table, with KSTAR between TPIK3-KSTRF and TPIK3-KSTRT, and other keys like Controlling Area and application/component (eg "PS" in project-system as in CJVC or "PM" in Maintenance as in IW33, multiple application use this table).

Where can I find the value of "_kks_use_mutex_pin"??
Hi, all.
Where can I find the value of "_kks_use_mutex_pin"??
What dictionary for "_**" parameter??
Thanks and Regards.Hi,
To find the value for a hidden parameter you must look in a hidden place:
SQL> select
2 x.ksppinm name,
3 y.ksppstvl value
4 from
5 sys.x$ksppi x,
6 sys.x$ksppcv y
7 where
8 x.inst_id=sys_context('userenv', 'instance') and
9 y.inst_id=sys_context('userenv', 'instance') and
10 x.indx=y.indx AND
11 x.ksppinm = '_kks_use_mutex_pin';
NAME VALUE
kksuse_mutex_pin FALSE
SQL> show user
USER is "SYS"
SQL>Only SYS can see these special views. However, this does beg the question why do you want to see the value of this parameter? Attempting to change this value without official Oracle support is Not A Good Idea and can leave your database unsupported.

I need to add the values stored in the session object into the html textbox
Dear Sir,
i have been trying to create an edit employee details page
What i have done till now is as follow:
1. Got employee id from HTML page.
2. Compared it with the id stored in the database.
3. If the id is correct then pulled the record of the corresponding employee and stored it in the session object.
4. Dispatched the session values to another servlet EditEmpDetails2.java
what i need to do now
5. Now i need to set the session values in the text field of the html form
6. I also need to be able to edit those vales and store the edited values in the database.
Please help me as i have tried doing it for 1 week without any clues
i have tried to create a html page which is something like this:
<html>
<head>
<title>Edit Employee Details Page</title>
<body BGCOLOR="red" text="black">
<h1 ><font color="black">Edit Employee Details Page</font></h1>
<form action = "EditEmpDetails" method="Get">
<table width="50% align="center"
<tr><td>Employee ID: </td>
<td><INPUT TYPE="TEXT" name="employeeid"<br></td></tr>
<tr><td><center><input type="submit" value="submit"></center></td></tr>
<tr><td><center><input type="reset" value="reset" ></center></td></tr>
</table>
</form>
</body>
</html>
design of my servlet EditEmpDetails.java
public void EditEmpDetails1 extends HttpServlet
public void doGet(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException
PrintWriter out = response.getWriter();
response.setContentType("text/html");
HttpSession session = request.getSession();
String employeeid;
String X = request.getParameter("employeeid");
System.out.println("Employee iD:" + X);
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con = DriverManager.getConnection("jdbc:odbc:murphy");
String query = "Select * from users where employeeid=?";
PreparedStatement stat = con.prepareStatement(query);
System.out.println(stat);
stat.setString(1,X);
ResultSet rs = stat.executeQuery();
while(rs.next())
String Z = rs.getString(password);
if(Z.equals(X))
String A = rs.getString(1);
session.setAttribute("employeeid", A);
String B = rs.getString(2);
session.setAttribute("firstname", B);
String C = rs.getString(3);
session.setAttribute("lastname", C);
String D = rs.getString(4);
session.setAttribute("gender", D);
String E = rs.getString(5);
session.setAttribute("dateofbirth", E);
String F = rs.getString(6);
session.setAttribute("address", F);
String G = rs.getString(7);
session.setAttribute("postalcode", G);
String H = rs.getString(8);
session.setAttribute("phone", H);
String I = rs.getString(9);
session.setAttribute("mobile", I);
String J = rs.getString(10);
String url = "/EditEmpDetao;s.java";
RequestDispatcher dispatcher = getServletContext().getRequestDispatcher(url)
dispatcher.forward(request,response);
catch (Exception e)
system.out.println(e)
I do not know how to put the values stored in the session object into the html text box3. If the id is correct then pulled the record of the corresponding employee and stored it in the session object.do you really need to store this in session object?
5. Now i need to set the session values in the text field of the html form which form? in a new html/jsp page? i suggest go for a JSP
In your JSP page use JSP expression tags to put the session attributes.
it's something like : <input type='text' name='employeeid' value='<%= session.getAttribute("employeeid") %>' >and you need to generateanother servlet for saving the details/modifications to the database.
I think i m clear enough.
if you need more clarifications. just try it and then post your problem.

Hi,
sorry, i got no idea how to get the datatype of a variant, but there are properties "ActualSize" and "Type" of the ADO Field-Object. In case of an empty field the ActualSize is zero. Maybe you can use that. See VI below.

How do I find the value of GWYUID from within a form?
Hi, can someone help me with the below?
I'm trying to determine the value of the environment variable GWYUID from within a form so I can pass this value to the fnd_webfile.get_url function at runtime to display the output of a concurrent program in a web browser.
I've tried the below but this just brings back null. Any ideas on how to find the value at runtime in 11i?
v_gwyuid varchar2(100) := name_in('$environments$.gwyuid');
fnd_message.set_string('GWYUID:'||v_gwyuid);
fnd_message.show;

How do you find the value of an iMac
Just curious how and where to find the value of my iMac 20 inch
Welcome!
Find your exact model from this list:
http://www.everymac.com/systems/apple/imac/index-imac.html
Then click its link. The full specifications have an estimated used price value near the bottom:
There are a lot of 20-inch iMac variants, so you need to at minimum do "About this Mac" to see what it shows for processor speed and type to find your model on the index.
The last update of estimated prices was done last August. Prices on that site tend to be at the top of the range. -
