Java Character Values
Hi ,
Please look into my following java programs:
public class Test{
public static void main(String args[]){
StringBuffer sb = new StringBuffer();
for(int i = 32;i<256;i++){
sb.append((char)i);
doThis(sb.toString());
public static void doThis(String str){
byte arr[] = str.getBytes();
int len = arr.length;
for(int i =0;i<len;i++){
char ch = (char)arr;
int ii = (int)ch;
System.out.println("character "+ch+ " value "+ ii);
when I run this program I get the output
as
character A value 65
once the character value reaches 127, then it prints as follow for next 32 enteries that is untill character actual value is 159..
character ? value 63
after characters actual value becomes more than 159 that it gives me huges vaules like as below:
character ? value 65440
character ? value 65535
any idea why?
I want to print the exact value of the characters?
thanks & Regards,
Akhil
char values are not the same thing as byte values in Java. Characters take 16 bit UNICODE values which represent not just the regular latin alphabet but all kind of exotic characters including Greek, Arabic, Hebrew, Chinese and so on.
When reading and writing text files these UNICODE characters have to be translated from or to byte values. The translation can use many different schemes. There are character encoding schemes designed for various national requirements, for example one where the bytes in the range 128-255 represent Greek characters. There are also international schemes like UTF-8. If you do an operation that changes bytes to characters or characters to bytes (like getBytes()) you generally have the option of specifying a scheme. If not the system uses a default based on your machine's location information.
In your case I guess the default is ASCII in which only characters up to 127 have valid mappings.
Had you put
byte arr[] = str.getBytes("ISO-LATIN-1");I think you'd get something more like what you expected.

Problem with display of a character (value 65533)
Hi all, sorry for my english but i don't speak it very well.
I have a big problem with the visualization of a character.
I have a binary text that i have to analyze with java. With my utility all works fine, but when i get the character (binary 81) and i analayze this character i obtain an int 65533 or a byte -3 , and after a casting to char i see that java doesn't display correctly this char, infact i obtain a char like this a question mark in a square. Even if a try to write this into a text file, i can see correctly all the other char, but instead of this char i see a question mark.
Someone know why i obtain this?i have to set some specific character encoding or something like this?
I don't know if this is usefull, but these are Hebrew char.
Thanks,bye.A character value of 65533 in not in the Unicode range for Hebrew and Java characters are Unicode encoded as UTF16. See http://www.unicode.org/charts/ .
65533 is not a byte value since bytes have a range -128 to +127 .
0x81 is not the same as 65533 decimal.
How are you converting the bytes of the file to characters?

Error while assigning a character value to a numeric variable.
I fire a sql statement and check the number of rows returned by the sql.
I check this result with the application logs.
The application logs keeps the sqls fired by the application and the no of rows returned, in the example below the sql returned 8454 rows.
My script compares the two results.
***********Application Log***********
4/14/2008 11:15:01 AM: 0059 SQL SELECT "CLUSTER_CD",
4/14/2008 11:15:01 AM: 0060 "PRODUCT_DESC",
4/14/2008 11:15:01 AM: 0061 "TEAM_CD"
4/14/2008 11:15:01 AM: 0062 FROM "OPS$TMS"."MAP_CLUSTER_TEAM_PROD"
4/14/2008 11:15:01 AM: 3 fields found: CLUSTER_CD, PRODUCT_DESC, TEAM_CD, 8,454 lines fetched
***********Application Log***********
My script:
#!/bin/ksh
typeset -i resA
typeset -i resB
opstms_conn_string="abc/[email protected]"
set `sqlplus -s $opstms_conn_string << EOF
set pages 0
WHENEVER SQLERROR CONTINUE
SELECT count(*)
FROM MAP_CLUSTER_TEAM_PROD;
exit
EOF`
resA=$1 ##returns 8454
resB=`grep '3 fields found: CLUSTER_CD, PRODUCT_DESC, TEAM_CD,' BCVP_Main_Loader.qvw.log | awk '{print $10}'`
##resB returns 8,454
## here i get syntax error
if [ $resA -eq $resB ]; then
echo "QA passed for sql1"
else
echo "QA failed for sql1"
fi
The problem is as resB is integer variable it does not accept character value: 8,454 so returns a syntax error:
How do I change the value assigned to resB into a numeric variable?
error:
+ grep 3 fields found: CLUSTER_CD, PRODUCT_DESC, TEAM_CD, BCVP_Main_Loader.qvw.log
run.ksh[52]: 8,454: syntax errorChange:
resB=`grep '3 fields found: CLUSTER_CD, PRODUCT_DESC, TEAM_CD,' BCVP_Main_Loader.qvw.log | awk '{print $10}'`
to this:
resB=`grep '3 fields found: CLUSTER_CD, PRODUCT_DESC, TEAM_CD,' BCVP_Main_Loader.qvw.log | awk '{print $10}' | tr -d ,`
to drop the comma. Or you could do it in awk(1):
resB=`grep '3 fields found: CLUSTER_CD, PRODUCT_DESC, TEAM_CD,' BCVP_Main_Loader.qvw.log | awk '{ gsub( /,/, "", $10 ); print $10}'`
Or you could to it all in awk(1):
resB=`awk '
/3 fields found: CLUSTER_CD, PRODUCT_DESC, TEAM_CD/ {
gsub( /,/, "", $10 )
print $10
' BCVP_Main_Loader.qvw.log`
(This example was not tested, it's just for a model.)
Someone more of an SQL guru than I can probably tell you how to change your numeric locale to avoid presenting those commas in the first place and avoid the problem.

How 2 assgin a character value to the auxillary cell
Hi,
I'm assigning a character value to the auxiliary cell in the macro. But it gives me a dump. So do let me know can I assign a character value to the auxiliary cell ( I need to display this value for the alert text).
Thanks,
Siva.Why are you trying to use a character in the planning book - why not a representative value in numbers
but if you HAVE to use characteristic then you can also try to use the notes functionality (right click on a cell and go to notes if you have not seen this )
These notes are usually anchored to a cell. These notes are stored in a table (check in se 16 with wildcard on notes ) and is associated to the value of a cell
So if you can reference a cell value and put in the conditons to the values on it you might be able to manipulate the values in the table for notes and this will cause the notes in the interactive planning boo to change accoring to the value of the cell -
Passing multiple character values from parameter form to PL/SQL
Hi,
I am passing multiple character values from parametr form into
the report query and a PL/SQL procedure. It works fine with the
query, when I use &variable. But, it doesn't compile in PL/SQL,
so I just used the :variable, but not getting any records in the
PL/SQL procedure. Any suggestions?
sincerely,
gjgj / Fedro,
Only using the &referecne, you can pas a string / multiple character values and this would work for query only.
The bind parameter in PL/SQL wouls support only single value

When I try to compile I receive an error that indicates the Java Home value is c:\jdk1.3.1. This was the correct value when I installed JDeveloper 9.0.3. However, since then I have installed a newer version of the JDK. I've changed the JAVA_HOME environment variable and the SetJavaHome parameter of jdev.conf, but still receive the error. Any suggestions?
The SetJavaHome parameter in jdev.conf is used to determine the Java SDK used to run JDeveloper. When JDeveloper is started for the very first time, this is also used to determine the default setting for the J2SE project setting (in the Libraries panel).

Character value can display automatically
Dear Experts,
i have a question for character value.
In BW, we have master data for PH1-PH6.
And if you know the PH6, there is unique value for PH1-PH5.
For example, if PH6 = 111111, PH1 = 1, PH2 = 11, PH3 = 111,etc.
This value is unique.
Now we have a excel layout for user to key in.
User only key in PH6, we want that the value for Ph1-Ph5 can fill-in automatically.
Just like user key in ph6 = 111111, ph1 = 1, ph2 = 11, ect.
I think characteritic relationship can achieve this requirment.
But question is that we must use the exit type for this requriment, am I right.
Can we use attribute or reference data or hierarchy ,etc to achieve this target?
If we use exit, we must create a function to support this requirement.
Thanks and best regards
Alex yangHi Alex,
you can do that easily with standard relationship, you need to have in the master data of PH6 the others PH as attrubutes, this way you can use char relationship based on master data. A similar way is to have a DSO with PH6 as a key and all the others PH and you can use C R with DSO. again hier is the same, if you have the hier you can easily set C R based on hier.
if you don't want to create such relations then you need exit relat.
hope this helps

Thanks,
SharonHi,
You can add directly the variable, in BEx Analyzer 7.0 you can add variables in the Excel Cell that you would.
Steps:
- Select the Excel Cell
- In the BEx Design Toolbox, select Insert text
- When you are in Design Mode - click over the text element
- Go to Constants tab and select the Custom Exit Variable
