Java - output from line read in reverse -

-

the following routine outputs moves chess engine jtextarea

public void getengineoutputoriginal(process engine)  {     try {                    bufferedreader reader =           new bufferedreader (new inputstreamreader (engine.getinputstream ()), 1);         string lineread = null;         // send engine analysis print method         while ((lineread = reader.readline ()) != null)            application.showengineanalysis (lineread);     }     catch (exception e) {                       e.printstacktrace();     } }

sample output be

           12     3.49  39/40?  2. b4      (656knps)                         12     3.49  40/40?  2. nd5     (656knps)                         12->   3.51   0.04   2. bxf4 be6 3. be3 qa5 4. nd5 qxd2            13     3.51   1/40?  2. bxf4    (655knps)

is possible reverse process last line read appears @ top instead of bottom, so:

           13     3.51   1/40?  2. bxf4    (655knps)               12->   3.51   0.04   2. bxf4 be6 3. be3 qa5 4. nd5 qxd2            12     3.49  40/40?  2. nd5     (656knps)                         12     3.49  39/40?  2. b4      (656knps)

i have researched google , couldn't find solution

sure! 1 option buffer lines arraylist, display them in reverse order @ end:

list<string> lines = new arraylist<string>();  /* add lines file buffer. */ while((lineread = reader.readline()) != null) {     lines.add(lineread); }  /* replay them in reverse order. */ (int = lines.size() - 1; >= 0; i--) {      application.showengineanalysis(lines.get(i)); }

conceptually speaking, can think of making stack, pushing lines onto stack, popping them off 1 @ time.

hope helps!

django - How can I change user group without delete record -

on website user have 1 group. , user can change group. it's made user.groups.clear() and user.groups.add(new_group) but it's not efficient, because there 2 sql query: delete, insert. how can change group update query? user , group related each other using manytomanyfield . means intersection table exists relating both entities, , if don't specify model map (using through attribute) django creates 1 you. looking @ sources django.contrib.auth.models see that's case. fortunatly, can access intermediary model using through attribute of manager (in case, user.groups.through ). can use regular model. example: >>> alice = user.objects.create_user('alice', 'alice@example.com', 'alicepw') >>> employee = group.objects.create(name='employee') >>> manager = group.objects.create(name='manager') >>> alice.groups.add(employee) >>> alice.groups.all() [<group: employee...

i need set custom soap header attribute on jax-ws generated webservice client. case webservice calls must go through proxy server requiring specific token (recieved web request header) present in soap request header. e.g.: 1 carserviceservice service = null; 2 service = new carserviceservice(new url(url), new qname(qname); 3 carserviceendpoint port = service.getcarserviceport(); it seems in line 3 wsdl retrieved , call fails due missing security token. 1 point direction on how done? a detailed example has been mentioned here: creating , deploying jax-ws web service on tomcat 6 this article shows how create , use security token .
