How to notify() the main method in the given code snippet

consider the given code snippet
code
public class WaitTest {
public static void main(String [] args) {
System.out.print("1 ") ;
synchronized(args) {
System.out.print("2 " ) ;
try {
args.wait();
catch(InterruptedException e){}
System.out.print("3 ");
code
Here since there are no threads to notify the main()method the statement System.out.print("3 "); never gets executed.And i cannot use the non static notify() from a static context.In this case how will I notify the main() method.

A thread can only do one thing at a time.
It cannot be waiting and notifying at the same time.
notify only works if another thread is waiting.
wait() only stops if another thread notify/notifyAll() it at the same time.

Plz help me on the hangman code

Consider the venerable "hangman" game, in which a player attempts to guess a word one letter at a time. If you are unfamiliar with hangman, simply google it; you'll be playing in no time.
Consider the following abstract view of hangman. The input is an unknown word and a sequence of character guesses. There is also an implicit parameter, which is the number of incorrect guesses that may be made before losing the game. Even though you wouldn't implement an interactive hangman game this way, let's model this as:
static public int hangman (String puzzle, String guesses, int limit)
Requires: puzzle != null, guesses != null, limit >=0
Effects: returns the number of the guess that solves the
puzzle within the given limit on incorrect guesses.
If the puzzle is not solved within the limit, returns -1.
e.g.
hangman ("cat", "abct", 1) is 4 (solved)
hangman ("cat", "abct", 0) is -1 (hit the limit)
hangman ("cat", "abcd", 5) is -1 (gave up)
I wrote the following code but it gives me an error of array index out of bounds exception though it compiles correctly. If someone can help me in correcting the code or point out my mistake.
public class hangman
public static int hang(String puz,String gue,int lim)
     int i,j,flag=0,ret=0;
     char p[],g[];
     p=puz.toCharArray();
     g=gue.toCharArray();

                    if(g==p[j])
                         //take the element off the p array and resize p
                         if(p.length==1)

                         else

I wrote the following code but it gives me an error
of array index out of bounds exception though it
compiles correctly.I just want to point out a fundamental misunderstanding that this statement suggests you have.
Compiling just converts your source code into equivalent bytecode. The only errors you'll get during compilation are if the syntax is bad (like you forgot a semicolon, misspelled a method name, have an extra closing brace, etc.) or if you're trying to ues a vairialbe that the copmiler can't be sure will have been initialized, etc.
Compilation does NOT execute your code, and it has no way to determine the logical problem with, for instance, int[] arr = new int[0];
int x = arr[999]; The fact that x has zero elements and you're trying to access element 999 only comes to light at execution time.
So "I get an error at runtime even though it compiles fine" is kind of meaningless.
Note that I'm not trying to pick on you here. I just want to shift your thinking away from this fundamental misconception you seem to have.

Problem in sending mail with the given code

package booodrive;
Some SMTP servers require a username and password authentication before you
can use their Server for Sending mail. This is most common with couple

it can be used in any your code for free.
Author : Sudhir Ancha
import javax.mail.*;
import javax.mail.internet.*;
import java.util.*;

To use this program, change values for the following three constants,
    SMTP_HOST_NAME -- Has your SMTP Host Name
    SMTP_AUTH_USER -- Has your SMTP Authentication UserName
    SMTP_AUTH_PWD -- Has your SMTP Authentication Password
Next change values for fields
emailMsgTxt -- Message Text for the Email
emailSubjectTxt -- Subject for email
emailFromAddress -- Email Address whose name will appears as "from" address
Next change value for "emailList".
This String array has List of all Email Addresses to Email Email needs to be sent to.

Your first step is to diagnose the problem.
1. Does the code compile? If not, what error messages appear?
2. Does the code run? If not, what error messages appear? What's in the stack trace?
3. Does the code do what you expect it to do? If not, what are the differences?

Help needed in understanding the Java code.

Hi All,
I have recently started learning the Java language. I came across this example and had a problem in understanding the output of the program. I could follow that if the continue statement is present in the below program the output is "Found 9 p's in the string" . But if the continue statement is removed I could not understand why the output would be "Found 35 p's in the string" .Is it because of the spaces and characters other than p... (eter ier icked a eck of ickled eers)
Example-----------------------
The continue statement skips the current iteration of a for, while , or do-while loop. The unlabeled form skips to the end of the innermost loop's body and evaluates the boolean expression that controls the loop. The following program, ContinueDemo , steps through a String, counting the occurences of the letter "p". If the current character is not a p, the continue statement skips the rest of the loop and proceeds to the next character. If it is a "p", the program increments the letter count.
class ContinueDemo {
public static void main(String[] args) {
String searchMe
= "peter piper picked a " +
"peck of pickled peppers";
int max = searchMe.length();
int numPs = 0;
for (int i = 0; i < max; i++) {
// interested only in p's
if (searchMe.charAt(i) != 'p')
continue;
// process p's
numPs++;
System.out.println("Found " +
numPs + " p's in the string.");
Here is the output of this program:
Found 9 p's in the string.
To see this effect more clearly, try removing the continue statement and recompiling. When you run the program again, the count will be wrong, saying that it found 35 p's instead of 9.

The answer is already in your example - "The unlabeled form skips to the end of the innermost loop's body and evaluates the boolean expression that controls the loop."
It unloads the current loop iteration when condition is matching. Loop is again starting from boolean expression inside loop declaration.

Please help me in understanding the following code.

public static void main(String args[]){
int x=0,c=0;
for(int i=0;i<3;i++)
x = x + x++;
System.out.println(x);
why this program always prints zero(0) as output. I am not able to understand the execution sequence of it.

Hi All,
I am just trying to understand the Java code in one Self Serice page. However, I am having tough in understanding the CO code. In the prosessRequest class, I have the below code.
oapagecontext.putTransactionValue("AddAssignmentInsertRowFlag", "N");
oaapplicationmodule.getTransaction().commit();
As soon as, oaapplicationmodule.getTransaction().commit();
gets executed, its calling some other class. Not sure what is being called, but i can see the log messages that its executing some other class which actually does the calls to DB APIs and inserting data into main tables.
Can you please explain me what is being called to make DB API calls. I would greatly appreciate your help.
Thanks in Advance!

Hi Rani,
As soon as the transaction is commited the methods in the VORowImpl Class are called.
You can check in the VORowImpl class and search for the log messages.
Thanks,

Regarding required ABAP knowledge to understand the APO-BW developments

Hi All,
Could you pls let me know what kind of ABAP skills that an APO consultant must have to understand the development code in the routines and user exits.
Best regards,
Ramya

Hi Ramya,
For ABAP consultant to work in APO, mainly you need to learn and
focus on working with structures.
Other areas for focus will be Badi's, user exits, function modules,
routines, enhancements which are more or less similar to other modules
Regards

How to understand this strange code?

Hi,everyone
When I analysing the petstore source code ,I find it very difficult to understand the following code,who can help me?please send email to [email protected]
thank you!
public XMLFilter setup(XMLReader reader) throws PopulateException {
return new XMLDBHandler(reader, rootTag, XML_INVENTORY) {
public void update() throws PopulateException {}
public void create() throws PopulateException {
createInventory(getValue(XML_ID), getValue(XML_QUANTITY, 0));
return;
}

This function is returning an anonymous class.
This new class is constructed and defined on the fly in this code.

Need to understand the relation between ManualResetEvent and thread

please help me to understand the below code
what is resetEvent.Set() and WaitOne() ? what it does ?
var resetEvent = new ManualResetEvent(false);
ThreadPool.QueueUserWorkItem(
arg =>
DoWork();
resetEvent.Set();
resetEvent.WaitOne();
again help me to understand the below code
var events = new List<ManualResetEvent>();
foreach(var job in jobs)
var resetEvent = new ManualResetEvent(false);
ThreadPool.QueueUserWorkItem(
arg =>
DoWork(job);
resetEvent.Set();
events.Add(resetEvent);
WaitHandle.WaitAll(events.ToArray());
why this line WaitHandle.WaitAll(events.ToArray()); is required ?
why adding ManualResetEvent instance to list ?
looking for discussion. thanks

WaitOne() will cause the current (main) thread to wait until the thread pool thread has called the Set() method. If you don't call the WaitOne() method, the code line below ThreadPool.QueueUserWorkItem(...) will get executed before the delegate that you
pass do the ThreadPool.QueueUserWorkItem method has actually finished its execution because the threads are being executed simultaneously:
var resetEvent = new ManualResetEvent(false);
ThreadPool.QueueUserWorkItem(
arg =>
//this will be executed simultaneously on thread B
Thread.Sleep(10000);
//tell thread A to continue
resetEvent.Set();
//thread A waits here until thread B calls the Set() method...
resetEvent.WaitOne();
string s = "abc"; //this line won't get executed until thread B has called the Set() method provided that the WaitOne() method is called by thread A above.
>>why this line WaitHandle.WaitAll(events.ToArray()); is required ?
It causes the main thread to wait until the Set method of all ManualResetEvent objects in the events list has been called. Othwerwise the execution of the main thread would continue immediately after the foreach loop has been executed. By this time the DoWork
method of all jobs has not yet been completed because they are being executed on another thread.
WaitHandle.WaitAll(events.ToArray());
string s = "abc"; //this line won't get executed until all the Set() method of all ManualResetEvent objects in events has been called
>>why adding ManualResetEvent instance to list ?
Because you (appearantly) want to wait for all objects in the list, i.e. you want to wait for the DoWork method to complete for all jobs before you continue the execution of the main thread (and go on to assign the string s to the value "abc"
in the above example).
Hope that helps.

Problem in understanding the code

this particular code is given as stadard example in sap unicode conversion
this particular code is replcement for 'translate code page syntax'
this code describes how to use particular cl_abap_conv_in_ce classs
i cannot understand the   'buffer' field in this code
can any one tell me what is the meaning of buffer = '41424320' from where did he get this value?
DATA:
    text(100) TYPE c,
    int TYPE i,
    buffer(4) TYPE x,
    conv TYPE REF TO cl_abap_conv_in_ce.
conv = cl_abap_conv_in_ce=>create(
          encoding = 'UTF-8'
          endian = 'L' ).
buffer = '41424320'.
conv->convert(
    EXPORTING input = buffer
    IMPORTING data = text ).
buffer = '02010000'.
conv->convert(
    EXPORTING input = buffer
    IMPORTING data = int ).

thank you mahmet i also want to check weather i am doing the code correct or not
i have old syntax in my program like    'TRANSLATE header-id FROM CODE PAGE file_tab-codepage'.
i am replacing the above syntax with the follwing code and can u correct me if i am wrong
data:
buffer1 type xstring,
conv type ref to cl_abap_conv_in_ce,
int type i.
conv = cl_abap_conv_in_ce=>create(
          encoding = 'file_tab-codepage'
          endian = 'L' ).
buffer1 = '41424320'.
conv->convert(
    exporting input = buffer1
    importing data = header-id ).

Plz meke me understand the given code!!!!!!
