Please help and don't close this thread

[Tawi]

Please open this: [ - shrink your URLs and get paid!] and tell me the reason Java process calculation in this program very long. Please do not close this because all of the advice was implemented by me but I get no good result.

Mod edit: suspicious link removed

[Norm]

all of the advice was implemented by me

Please copy the results of the debug techniques that were suggested and paste them here.
There were two different suggestions:
1) profiling
2) computing times that sections of code took to execute and print those times out


The other post on this same topic: http://www.java-forums.org/new-java/...very-long.html

[jim829]

No one is going to visit that site. You already dumped your code here --> http://www.java-forums.org/new-java/...y-program.html. Six posts of it. No one is going to spend the time to analyze all of that. You need to learn the fundamentals of programming and design. I suggest you start with The Java™ Tutorials and a good book. Please stop asking for help on this.

Regards,
Jim

I posted the result in the previous thread for profiling. About the computing time, Java does not do any things after I click the button that is being named "Proses" by me. So? What next? If you don't believe me, download the file or let me dump the code in this thread ok?

I posted the result in the previous thread for profiling.

Please try it again and make sure there are no errors. When posting make sure to copy all of the contents of the command prompt window including the command line that started the execution.

Java do not do any things after I click the button

Then you need to add lots more calls to the println() method to show where the code is being executed. Be sure to put a println() before and after every method call. For example:

  long startTime1 = System.currentTimeMillis();  // save start time
  System.out.println("Calling method1 at "+startTime1);
  method1();  //  call method1
  System.out.println("end method1 duration="+(System.currentTimeMillis()-startTime1)); //  report how long it took

You should add the above around ALL method calls.

The output for each method call should look like this:

Calling method1 at 1393035987338
end method1 duration=3328

Done, so? What does this mean? What next?

I already did it but Java did not do any things after I clicked the button, so? What next?

Where is the commandline that started the test? There should be a line that starts like:
java -Xprof ....

That report says the program finished execution in less than one second? Where is the problem then?

Here is an example of what needs to be posted:

[Tawi]

Try to download and run the program. After that please write your computer specifications if you can run it. If I need more sophisticated computer to run the program please tell me the minimum requirements to be able to run the program because Java does not do any things in here.

[Norm]

If you are not going to follow any of the advice given to you, what is the use of keeping this thread open?
It's a waste of time to repeat what has already been said on the two other threads.

Try to do one or both of the debugging techniques you have been shown.

I did it. The problem is I do not know your computer specifications. If you can run the program well, please tell me your computer specifications. In other words, what kind of minimum computer specifications shall I use to run the program? The Java reports no error, so?

[Norm]

You need to copy ALL of the contents of the command prompt window and paste it here.
You are wasting time by not following instructions.

What about adding the println()s?

[Tawi]

No content in the command prompt. I revised the code heavily. Where shall I put the println()?

[milovan]

what you use to run this program? some IDE or command prompt (terminal)

[Norm]

Where shall I put the println()?

See post#5

[AlexGraal]

I'm so confused by this thread. What do you even want help with?

Typically, if I've got a complicated program:

class complicatedProgram {
  public static void main ( String[] args ) {
    String s = "hey";
    int a1 = 67;
    int a2 = 89;
    int total = add(a1, a2);
    int a3 = convertToInt(s);
    int finalTotal = add(total, a3);
    String answer = convertToString(total);
  }
  //methods for add, convertToInt, and convertToString here
}

and it runs very slowly - or simply doesn't finish, I add println()s to tell me where the actual time is taking.

So I would do this:

class complicatedProgram {
  public static void main ( String[] args ) {
    String s = "hey";
    int a1 = 67;
    int a2 = 89;
    System.out.println("Call 1");
    int total = add(a1, a2);
    System.out.println("Call 2");
    int a3 = convertToInt(s);
    System.out.println("Call 3");
    int finalTotal = add(total, a3);
    System.out.println("Call 4");
    String answer = convertToString(total);
    System.out.println("Call 5");
  }
  //methods for add, convertToInt, and convertToString here
}

Then, I can see what the last call is. After that call is the line that is taking forever/very long. Helps you catch infinite loops and such.

That's all been covered before with this person. Two of the OP's threads have been closed. And similar posts are at JavaRanch where the advice and frustration from the repliers has been the same.

Jim

[AlexGraal]

Well until the thread is closed, there is nothing to do but post answers.

Some people don't understand English very well. Others simply may need to see an answer a certain way to understand or may not be as quick as you.

It won't hurt to restate what somebody already said.

[jim829]

It has nothing to do with understanding English. It is clear the poster understood what was being asked. The poster continued to refuse to follow the advice. Of course, you may do as you see fit.

Sirs, I am sorry if you think that I am rude but after I put the println statement, the other button become long at the time they are processing, what shall I do?

I did all of your advise. So? What next?

[Tawi]

Please try it again and make sure there are no errors. When posting make sure to copy all of the contents of the command prompt window including the command line that started the execution.


Then you need to add lots more calls to the println() method to show where the code is being executed. Be sure to put a println() before and after every method call. For example:

  long startTime1 = System.currentTimeMillis();  // save start time
  System.out.println("Calling method1 at "+startTime1);
  method1();  //  call method1
  System.out.println("end method1 duration="+(System.currentTimeMillis()-startTime1)); //  report how long it took

You should add the above around ALL method calls.

The output for each method call should look like this:

I did this sirs but the Java did not giving any outputs. It just did not show any things.
