java - Advantages/Disadvantages of code location when accessing Resource file -


here 3 options have seen when accessing resource file. option 1 least recommended due potential of exceptions question pertains option 2 or 3 preferred or recommended implementation.

option 1 - done in attributes area. generic. doesn't capture potential exceptions. 

class myclass  {     static resourcebundle bundle = resource.getbundle("myfile");     float value1 = float.parsefloat(bundle.getstring("myvalue1"));     float value2 = float.parsefloat(bundle.getstring("myvalue2")); }

option 2 - access resources within constructor. since values won't dynamic seems waste access them every time class instantiated class heavily used item. 

class myclass  {     static resourcebundle bundle = resource.getbundle("myfile");     float value1;      float value2;      public myclass()     {         try         {             value1; = float.parsefloat(bundle.getstring("myvalue1"));             value2 = float.parsefloat(bundle.getstring("myvalue2"));         }catch(exception e)         {             //do         }     } }

option 3 - code within attributes section of class. accessed once if class in memory, since attributes tend @ top of class, make code appear cluttered try/catch , code. 

class myclass  {     static resourcebundle bundle = resource.getbundle("myfile");     float value1;      float value2;     {         try         {             value1; = float.parsefloat(bundle.getstring("myvalue1"));             value2 = float.parsefloat(bundle.getstring("myvalue2"));         }catch(exception e)         {             //do         }     } }

seems more matter of preference else don't expect overhead difference measurable if there 20-30 resources being accessed.

your option 2 , 3 produce same bytecode. difference aesthetical.

i using winscp .net assembly uploading files. want upload multiple files asynchronous way. have created method works single upload. public class uploadingdata { private sessionoptions _sessionoptions; private session _session; //connection etc private void onconnected() { foreach (var fileinfo in localfileslist) { var task = task.factory.startnew(() => uploadfilesasync(fileinfo)); } } private async task uploadfilesasync(string file) { string remotefilepath = _session.translatelocalpathtoremote(file, @"/", "/test_data_upload"); var uploading = _session.putfiles(file, remotefilepath, false); //when done await task.run(() => thread.sleep(1000)); } } please suggest me correct way. thanks you can use backgroundworker class this: string[] images = new string[50]; foreach (var path in images) { backgroundworker
