Can anybody explain this code ?

try {
InetAddress addr = InetAddress.getByName("java.sun.com");
byte[] ipAddr = addr.getAddress();
String ipAddrStr = "";
for (int i=0; i<ipAddr.length; i++) {
if (i > 0) {
ipAddrStr += ".";
ipAddrStr += ipAddr&0xFF;
} catch (UnknownHostException e) {

Man, that's a hideous piece of code. Judging from
this line (I'm assuming the array index)...
ipAddrStr += ipAddr&0xFF;
...the code was cribbed from some other code that
applied a bitmask by someone who didn't know the API
very well, but was somewhat familiar with C.
Actually, if the method to retrieve the IP as a string didn't exist, that's exactly what I'd do. The array returned by InetAddress.getAddress() is a byte[] and, since Java uses only signed data types, you wouldn't want to inadvertently get a string containing "-64.-88.0.1" instead of "192.168.0.1".
You'll note that "& 0xFF" is a mask to an integer constant. That means that the byte (ex., -127 or 0x81) gets upcasted to an integer first (0xFFFFFF81) and then everything but the lowest order byte is cleared (0x00000081) which, indeed, gives us the "unsigned" version of that byte.
It's not at all pretty, of course. But it is pretty much the best way I know to get a value from 0-255 out of a byte in Java.
EDIT:
Oh, btw... you won't get any disagreement from me on the topic of the person not knowing the API very well. :)

Can anybody explain this S_OUT-MAKTX+0(20)?

can anybody explain this S_OUT-MAKTX+0(20)? what 0(20) implies?

Here .. u r going to use onli the first 20 characters from the beginning of the string S_OUT-MAKTX..
seee...
suppose w_char is a variable of type C of 30 characters length and having the content as 'SAP-ABAP FORUMS'.
i.e w_char = 'SAP-ABAP FORUMS'.
now
w_char+0(4) = 'SAP-'.
W_CHAR+1(4) = 'AP-A'.
W_CHAR+3(5) = '-ABAP'.
i.e Starting from the Third character and upto 5 characters... AND here the counting of the characters starts from 0.
Hope u understood...

Can anyone explain this code snippet

I'm revising for my exams and this is one of the question that came up in the previous exams. Can someone help answe the questions at the end. Also what object is 'time_t' and how why do they use 'input_time -= 24*60*60;'?
Read the following code carefully before answering the questions.
time_t normalise(time_t input_time)
     bool finished;
     // This produces a formatted time string like:
     // Thu_Nov_24_18:22:48_1986
     string str_time = format_time( input_time );
     while( str_time.substr(1,3) != "Sun")
          input_time -= 24*60*60;
          str_time = format_time( input_time );
     while( str_time.substr(11,2) != "00" )
          input_time -= 60*60;
          str_time = format_time( input_time );
     while( str_time.substr(14,2) != "00")
          str_time = format_time( input_time );
          input_time -= 60;
     while( str_time.substr(17,2) != "00")
          input_time -= 1;
          str_time = format_time( input_time );
     return input_time;
1) Briefly explain what you think the overall purpose of this function is (do not describe each line of code).
2) There are two bugs in this code that prevent it from functioning correctly; circle them.
3) What would actually happen when this code is run?
(a) as originally written
(b) with the first bug fixed?
4) Discuss the efficiency of the code assuming the bugs have been fixed.

Looks like it is trying to increment the time parameter back to represent midnight of the previous Sunday.

Can anybody explain dis code for calling constructors in main method?

it is used in netbeans IDE and m nt getting what is happening here

            public void run() {
                new MainMenu().setVisible(true);

Can anyone explain this code!

DECLARE
TYPE t_NumberTableType IS TABLE OF NUMBER
INDEX BY BINARY_INTEGER;
v_NumberTable t_NumberTableType;
v_TempVar NUMBER;
BEGIN
v_TempVar := v_NumberTable(1);
END;
/

That code assigns to the variable named v_TempVar the first value of the v_NumberTable collection.
However, with no input at sight it seems pretty useless and buggy since you will get an error because no value was assigned.

Hi,
JNDI needs some property such as the
java.naming.factory.initial
java.naming.provider.url
which are needed by the
InitialContext(env);
where env is a properties object
Now if you can not find the physical property file on the class path
by AtccJndiTemplate.class.getResourceAsStream(this.jndiProperties);
where the String "jndiProperties" get injected by certain IOC ( inverse of control container ) such as Spring framework
if not found then it will take the property from the system which will come from the evniromental variables which are set during the application start up i.e through the command line
java -Djava.naming.factory.initial=com.sun.jndi.ldap.LdapCtxFactory -Danother=value etc..
I hope this could help

Can anybody explain all the details about idoc like configuration settings etc..

Hi all can anybody explain the idoc configuration settings, communication channels sender and receiver settings

Hi,
Common steps in both Sender and Receiver:
Create logical system and assign to client
Create RFC Destinations in SM59
Create RFC Ports in WE21
Steps in Sender
Create table in SE11 and insert data
Create Segments in Tcode WE31.Define the table fields in segment
Create basic IDOC type in WE30.Specify the above created segment name,save and release the IDOC
Create message type in WE81
Assign message type to IDOC type in WE82 and release
Create partner profile in BD64,add the message type ,specify sender,receiver,message type and generate partner profile and execute.Distribute the model view
Check the partner profile in WE20
Develop a report in SE38 with code that transfers the data from source to destination
Execute the report and specify the fields to be transferred
Check the control records in WE02
Steps in Receiver:
Create an update function module in SE37
Assign the function module to logical message
Define input method in Tcode BD51
Create process code in WE42
Generate partner profile in BD64
After executing the report in sender system check in the destination system table wheather the fields are transferred
In this case a custom table has been created in sender and receiver with same structure.We can even transfer the standard table fields by using idocs

Generic Extraction via Function Module
/people/siegfried.szameitat/blog/2005/09/29/generic-extraction-via-function-module
1. Create s structure with the fields that you need from the 4 tables . Activate.
2. Goto SE 80 Select The Function Group , Copy , Select the Function module
" RSAX_BIW_GET_DATA_SIMPLE " and Give a New name starting With
Y or Z .
3. SE37 ->Your Function module name -> Change , In table tab give your structure
name by deleting the associated type given in " E_T_DATA " .
4. Now select source code and Do the coding . Give Data source name in Coding .
In your case you have to take data from more that 1 table .
5. Activate the Function Group .
6. In RSO2 Create the Data source , Give the Function Module Name , And Save.
7. RSA3 -> Give data source name and Check for the Records .
Creation of custom datasource. (Using function module)
is an example
1.Create a function group .
2. Structure ZTEST123

CAN ANYBODY EXPLAIN ME THE GENERAL FUNCTIONING OF THE SD, MM, PP MODULES.

Hi Santosh,
Seems u r new to SAP.
SD, MM, PP, FI ,CO,CRM ,etc... are the functional areas dealing in the SAP R/3 ERP.
They all have their own transaction code and tables. But all are integrated and related to each other.
For more info check these links.

Can anyone explain this to me, please. It's a static section question.

Can anyone explain this to me, please. It's a static section question.
I came across the following style of programming recently and I would like to know what the Static section is actually doing in the class. Thx.
Here is the code.
public class ClassA {
     private static Hashtable ClassAList = new Hashtable();
     private ClassB cB;
     private Vector goodLink;
     private Hashtable classCList;
     static
          ClassA cA = new ClassA();
          ClassAList.put("whatever", cA);
     public static ClassA getClassA()
          return (ClassA) ClassAList.get("whatever");

hi,
The static section shall be loaded before it's constructor is called. (i.e at the time of loading the class). Therefore making it available for any other objects to call.
hope this clarifies ur question
