How to get user input to keep in array in the form of int[]?
I really want to know how to get user input to keep in an array. Or if it's impossible, can i use the value in "int" and transfer it to an array?
What I understand is that you want to set an input from the user in an array of int.
Here is how it work:
1. Create a stream and a buffer to get and store the informations entered by the user:
BufferedReader stdin = new BufferedReader(new InputStreamReader(System.in));
2. Set this input in a String:
String input = stdin.readLine();
3. Set this string in an int:
int userInput = Integer.parseInt(input);
4. Then you can put this int in the array.
Warning this code throws IOExceptions and NumberFormatException ( when you try to set letters as int ). But you can catch them easily. -

How to get form input in the same portlet using pageflow
Hi this is premkumar
i created 2 portlet in a portal how to get form input in the sampe portlet using
pageflow
help as early as possibleDo to the complexity of the program we need to run it with sequences. This is because we need to aquire data with DAQ until it reaches a certain point and then stop collecting so that it can do its process (only once for all times criteria is met), and then loop around till again collecting after DAQ drops back below certain point looking to once again reach that point. Another flat sequence is going outside of this where I want to put the prompt and have a user input to affect how many times that that the inner loop is run (No a For Loop instead of the while loop will not work either for other reasons).
I just want to know if after the program starts you can have a user input that will change the effect of the rest of the programs action based on the number inputed. -
How to get user logged in to ironport web
How to get user logged in to ironport web by their username, time connected and the IP address?
The onbox reporting can only show what web traffic is currently being surfed. We can provide a near-real time view of this web traffic with a "Web Tracking Report".
However, there is not a report available that depicts what you're describing. (This information is best contained on the domain server). The closes we could get with the WSA is displaying which credentials we are currently caching. (Which users we've seen since within the surrogate timeout). This is possible with the authcache command on the cli.

Problems with getting user input
Hi All,
I want to get user input from a command line and i am NOT using a GUI.
The user can still see their password when they are typing it in.
Is there anyway to show '******' when they type in their password??
This is what I have so far..
public static void getPassword() {
System.out.print("Enter password-->");
DataInputStream input = new DataInputStream(System.in);
try{
password = input.readLine();
catch (IOException e){
System.out.println("ERROR " + e);
Any help would be greatly appreciated.
Thanks
Kal.Kal,
I'm pretty sure you're going to need some kind of GUI (either a Java window or an HTML page) to get the desired effect. There might be a way to set the echo character in the command line, but I'm not sure.

How to capture user input for customer exit processing?
I need to calculate the number of working days elapsed in the current fiscal quarter BASED on the USER INPUT on the reporting front. i.e., say the fiscal quarter started on 1 July 2005 and if the user enters 10 July 2005, I should get the value 8 (Assume that Monday through Friday are all workdays). If the user enters 12 July 2005, I should get 10. I have written customer exits and know how to use factory calendar, but <b>THE CHALLENGE</b> is how do I <b>CAPTURE</b> the user input and use it in my exit? During the varible definition, if I select the check box "Ready for input" then the customer exit is not being processed and unless I check that box I can't get a user entry! If I look at the import values in the customer exit, I see i_t_var_range with type rrs0_t_var_range. My strong feeling is that this parameter gets the user input, but I am unable to use it as the customer exit is not being called if I make the user to input the data. Based on the empirical evidence, I felt that user input and customer exit can not co-exist!! Please somebody prove me wrong and let me know how can I use the user input to process my "customer-exit" variable. I would really appreciate any input from the BW community here.
Hi Sameer,
Most likely, I'm missing something, but I think that the answer is very simple.
CASE I_VNAM.
WHEN 'YOUR_CUSTOMER_EXIT_VAR'.
IF I_STEP = 2. After selecting of input variable
LOOP AT I_T_VAR_RANGE INTO LOC_VAR_RANGE
WHERE VNAM = 'USER_INPUT_VAR'.
CLEAR L_S_RANGE.
L_S_RANGE-LOW = LOC_VAR_RANGE-LOW(4).
APPEND L_S_RANGE TO E_T_RANGE.
ENDLOOP.
ENDIF.
ENDCASE.
In this typical user exit coding you have a user entered value in LOC_VAR_RANGE (originally in I_T_VAR_RANGE) and you construct your user exit variable value in E_T_RANGE.
Best regards,
Eugene

How to accept user inputs from sql script
I want to create Tablespace useing sql script , but the location of the data file I need accept from user . (to get the location of the data file ) .
How can I accept user input from pl/sql .
Example :
CREATE TABLESPACE TSPACE_INDIA LOGGING
DATAFILE 'H:\ORACLE_DATA\FRSDB\TSPACE_INDI_D1_01.dbf'
SIZE 500M AUTOEXTEND ON NEXT 1280K MAXSIZE UNLIMITED
EXTENT MANAGEMENT LOCAL;here I need to accept location of the datafile from user ie : 'H:\ORACLE_DATA\FRSDB\TSPACE_INDI_D1_01.dbf'Hi,
Whenenever you write dynamic SQL, put the SQL text into a variable. During development, display the variable instead of executing it. If it looks okay, then you can try executing it in addition to displaying it. When you're finished testing, then you can comment out or delete the display.
For example:
SET SERVEROUTPUT ON
DECLARE
flocation VARCHAR2 (300);
sql_txt VARCHAR2 (1000);
BEGIN
SELECT '&Enter_The_Path'
INTO flocation
FROM dual;
sql_txt := 'CREATE TABLESPACE SRC_TSPACE_INDIA LOGGING
DATAFILE' || flocation || ' "\SRC_TSPACE_INDI_D1_01.dbf" ' || '
SIZE 500M AUTOEXTEND ON NEXT 1280K MAXSIZE UNLIMITED
EXTENT MANAGEMENT LOCAL ';
dbms_output.put_line (sql_txt || ' = sql_txt');
-- EXECUTE IMMEDIATE sql_txt;
END;
/When you run it, you'll see something like this:
Enter value for enter_the_path: c:\d\fubar
old 5: SELECT '&Enter_The_Path'
new 5: SELECT 'c:\d\fubar'
CREATE TABLESPACE SRC_TSPACE_INDIA LOGGING
DATAFILEc:\d\fubar
"\SRC_TSPACE_INDI_D1_01.dbf"
SIZE 500M AUTOEXTEND ON NEXT 1280K MAXSIZE
UNLIMITED
EXTENT MANAGEMENT LOCAL = sql_txt
PL/SQL procedure successfully completed.This makes it easy to see that you're missing a space after the keyword DATAFILE. There are other errrors, too. For example, the path name has to be inside the quotes with the file name, without a line-feed between them, and the quotes should be single-quotes, not double-quotes.
Is there some reason why you're using PL/SQL? In SQL, you can just say:
CREATE TABLESPACE SRC_TSPACE_INDIA LOGGING
DATAFILE '&Enter_The_Path\SRC_TSPACE_INDI_D1_01.dbf'
SIZE 500M AUTOEXTEND ON NEXT 1280K MAXSIZE UNLIMITED
EXTENT MANAGEMENT LOCAL;though I would use an ACCEPT command to given a better prompt.
Given that you want to use PL/SQL, you could assign the value above to sql_txt. If you need a separate PL/SQL variable for flocation, then you can assign it without using dual, for example:
DECLARE
flocation VARCHAR2 (300) := '&Enter_The_Path';The dual table isn't needed very much in PL/SQL.

How to save User input into DB using webdynpro abap
Hi,
Im trying to create an application using webdynpro abap.
I want to know how to save the data input by user, into a database table.
In my UI, I have a table control which is editable and user inputs data into this. I need to know how i can transfer this data to a DB table.hello,
u can do it by reading ur context node.
we bind our UI elements to context attributes of appropriate type .
we read their values using the code wizard or by pressing control+F7, click on radio button read node/attribute
here for ur specific case , u must have binded ur table control with the context attribute , now u need to simply read this attribute
eg suppose u have created a context node " cn_table"
reading context node cn_table
DATA : lo_nd_cn_table TYPE REF TO if_wd_context_node ,
lo_el_cn_table TYPE REF TO if_wd_context_element ,
ls_cn_table TYPE wd_this->element_cn_table.
* navigate from <CONTEXT> to <CN_TABLE> via lead selection
lo_nd_cn_table = wd_context->get_child_node(
name = wd_this->wdctx_cn_table ).
** get element via lead selection
lo_el_cn_table = lo_nd_cn_table->get_lead_selection( ).
lo_el_cn_table->get_static_attributes( IMPORTING
static_attributes = wa_table ).
here wa_table is the work area of structure type . u need to create a structure first with the same variables as there are the context attributes in ur node cn_table
in ur
now ur wa_tablecontains value
u can nw use appropriate FM to update , delete and modify the DB table using the value
u cn directly use SQL statements as well in the method of ur view , but direct SQL statements are nt recommende

Hi everyone ! I know how to get a user input if it's a string, but how do I take integer input ?
Get the string, use
Integer.parseInt()
to convert it to an int. If parseInt() throws a NumberFormatException, the user put in non-numeric data. -

Getting user input in Textfield
I have a textfield called "time" in a JPanel, on a JFrame.
When i try getting the user input,
int t = Integer.parseInt(time.getText());
I have a nullpointer exception error.
my code is something like this.
JTextField Time = new JTextField(2);
Time.addActionListener(this);
int t = Integer.parseInt(Time.getText());Is there anything that I miss out?
The above textfield is located in a JPanel, which is located in another JPanel for layout purposes, is that the reason that it cant work?Is the explanation for the above the same as your last post?
No. The last post (reply 10) was about a way to avoid having to declare a variable, JButton in particular, in class scope.
I did try to explain the answer to you question in reply 11 in reply 9. The comments in the code point out what is happening with the scope to explain why one way works and the other does not.
I'll try again. Let's start with a couple of definitions. A declaration is this
JTextField Text;where JTextField is the type and Text is the name of the variable. We have declared a variable named Text of type JTextField. Now java knows that any time it encounters the variable Time that it is a JTextField.
Next is instantiation
Text = new JTextField(2);Here we have instantiated the variable Time and it now points to a real JTextField. You can do both declaration and instantiation at the same time like this
JTextField Text = new JTextField(2);So on to the issue of scope. Consider your first code block from above
public class MyClient1 extends JFrame implements ActionListener
JLabel Length;
JTextField Time;
JButton Clear, Play;
public MyClient1()
JButton Play = new JButton(" Play ");
Play.addActionListener(this);
Play.setBounds(410,0,90,20);
JButton Clear = new JButton(" Clear ");
Clear.addActionListener(this);
Clear.setBounds(310,0,90,20);
JTextField Time = new JTextField(2); //the JTextField is present and it can't work
Time.addActionListener(this);
Time.setBounds(80,0,40,20);
Time.setText("0");
}You have declared and instantiated the variable Text inside the constructor. This variable is therefore private to this constructor, ie the method whose body is inside the curley braces {...}. No one outside these curley braces can ever know that there exists something called Time. So the code in your actionPerformed method does not have access to Time and when you try to use the variable it will throw a NullPointerException, ie, java is saying it doesn't exist — it is null. You can test this by adding a line like this System.out.println("Test = " + Test); in the actionPerformed method.
The declaration in class scope, ie, this line
JTextField Time;placed above the constructor is still null because it has not been instantiated.
In the second code block you did instantiate this member variable declaration inside the constructor. They are the same thing, the declaration and the instantiation are referring to the same object. Success! But in the first code block the member variable declaration and the declaration–and–instantiation statement inside the constructor are not even related, they are not the same.
The java tutorial explains this in Scope. They use the word visibility in a more specialized way than I have above.
