DataStructure for client-server communication 10 Years Ago by getmeusername …. Please help me how should I approach in creating such datastructure. Thanks Looking for suitable datastructure 13 Years Ago by Slimmy …) or 2. Throw out the hashmap and apply a new datastructure that actually does what I want. Anyone got any suggestions… this? Im not to excited about writing my own specific datastructure for this since it's overall a fairly small task… Can u suggest any better link for datastructure explains with diagrams? 14 Years Ago by ramjeev Can u suggest any better link for datastructure that explains with diagrams?It would be good,if any basic level explanation with algorithms. Re: DataStructure for client-server communication 10 Years Ago by Paul.Esson Personally I would send the type followed by 2 bytes for the size ( unless the type dictated size ) For instance If : INT = 1; STRING = 2; Then sending the int 5 followed by the string HELLO would result in the following message 01 00 00 00 05 02 00 05 48 45 4C 4C 4F If you use the terminiating char for the string then you don… Re: DataStructure for client-server communication 10 Years Ago by Paul.Esson You may want to encode and decode from some form of linked list, if you need anymore type information ( for instance, some messages may go to controller x and some to controller y, then just add a byte to dictate that as well ). Re: DataStructure for client-server communication 10 Years Ago by getmeusername Thanks Paul. Is it possible to send all data in one shot ? Here number of data will be generated dynamically by some controller. So at one time client will have 5sets of varibale or at one some n sets of variable. I am looking for unique client-server code that will independent of number of data send in one shot. Your inputs will help me to design… Re: DataStructure for client-server communication 10 Years Ago by Paul.Esson If you're using UDP 65,507 bytes is the largest size, for TCP it's 1GB. If you're using TCP there is very little reason not to send the data in smaller chunks, then combining the buffers again at the other end. TCP should deal with the order of the packets, but if you're going to take this approch you may also want to have 4 bytes at the start … Re: DataStructure for client-server communication 10 Years Ago by getmeusername Thanks Paul...this would help me. Re: DataStructure for client-server communication 10 Years Ago by Ancient Dragon UDP is not recommended for long distances because there is no guarentee that the packets will ever arrive. TCP is best for that. DataStructure help!! 13 Years Ago by newbieha I have a class that contains two arraylists- student names and Ids I want to put them into LinkedHashSet( so, I can sort, delete, add and edit e student profile); I created a class called Student that contains setName getName setId getId and toString methods. now, I try to do something like [CODE]LinkedHashSet<Student> list=new … Re: DataStructure help!! 13 Years Ago by JamesCherrill You have 2 nested loops, which will get you every possible combination of name & id. But what you want is just the matching name & id for the same student - something like [CODE]for i = 0 to (number of students) list.add (new Student(studentName.get(i), studentID.get(i)) ... for (Student s : list) { System.out.println(s.getName() + s.… Re: DataStructure help!! 13 Years Ago by newbieha Thanks JamesCherrill. This is my delete method. can you see any errors? It outputs "not in the list"(I double checked my input and compare to the item in the list. Im sure they are exactly same. [CODE] String st; String st2; st=JOptionPane.showInputDialog("Enter a name (Ex: James Acosta)"); st2=JOptionPane.showInputDialog("… Re: DataStructure help!! 13 Years Ago by JamesCherrill if(pn.equals(onestudent)==true 1. the == true is totally redundant. if(pn.equals(onestudent) the equals method inherited from Object compares pn and onestudent to see if they are exactly the same Object. But onepperson is a new Student object that you just created, so it's never the same Object. What you need to do is to override the equals method … datastructure 11 Years Ago by rithish i would like to start data structures in c langauage.but i dont know even what is data structure and 0% about data structure.can u suggest me some books for data structure in c?????

Would somebody our there help me?

I can delete it but the PROFILE number still there. I want it to be deleted also when I delete the data.[/QUOTE] You need to do one of two things to truly erase the data: [list] [*]Overwrite the record in your file with default data (such as whitespace) [*]Rewrite your file and … Re: Datastructure (Sorting data) 12 Years Ago by danieldane Ok thanks. I will try it later. Re: Datastructure (Sorting data) 12 Years Ago by danieldane Hello one thing, could you give me sample code how to sort out: when I add PERSONAL PROFILE then save it and I can DELETE PROFILE including PROFILE NUMBER. I'm confuse now because of many thing in my head. Thank you. Re: Datastructure (Sorting data) 12 Years Ago by Narue [QUOTE]I'm confuse now because of many thing in my head.[/QUOTE] Then simplify. If you're overwhelmed, throw stuff out until it becomes manageable. Once you have a bunch of manageable pieces working, putting them all together is easier. Re: Datastructure (Sorting data) 12 Years Ago by rubberman Narue is right on the money here. The KISS principle is the foundation of good programming. Re: Looking for suitable datastructure 13 Years Ago by Ancient Dragon You mean you want to sort the array without actually swapping array values? I have done that before but used a second array of intgers that represent the array indices. [code] float data[5] = {3,1,4,9,2}; int indices[5] = {0,1,2,3,4}; // sort the data for(int i = 0; i < 4; i++) { for(int j = i+1; j < 5; j++) { if( data[… Re: Looking for suitable datastructure 13 Years Ago by Slimmy Looks promising!
