Java reads and writes files according to the specified Encoding

 

Arraylist <string> namearr = new arraylist ();
Stringbuilder builder = new stringbuilder ();
Try {
String txtpath = "C: \ name 2.txt ";
String txtnewpath = "C: \ name 3.txt ";
Bufferedreader reader = new bufferedreader (New inputstreamreader (

String [] names = line. Split ("");
For (string name: names ){
If (name. Length ()> 2)
{

Java RCP development to obtain files under the application Workspace

/**
* Obtain the database path
* @ Return
*/
Public static string getdb (){
Location instancelocation = platform. getinstancelocation ();
URL path = instancelocation. geturl ();
String strpath = path. getpath () + "Gs. DB ";
Return strpath;
}

 

Obtain the startup path of the RCP Application

 

File bundlefile = NULL;
Try {
 Bundlefile = filelocator. getbundlefile (activator. getdefault (). getbundle ());
} Catch (ioexception e ){
// Todo auto-generated Catch Block
E. printstacktrace ();
}
If (bundlefile = NULL)
Return NULL;
File geosearchfolder = bundlefile. getabsolutefile ();
String geosearchdisk = geosearchfolder. getparent ();

 

Obtain the corresponding view object based on The View ID.

String viewid = "com. geocompass. geosearch. Views. filejudger ";
Iviewpart part = platformui. getworkbench (). getactiveworkbenchwindow (). getactivepage (). findview (viewid );
Filejudgerview judgeview = (filejudgerview) part;
Judgeview. reloaddata ();

 

 

Java Open folder:

 

Java. AWT. desktop. getdesktop (). Open (NewFile ("D: \ Java"));

 

Delete folders and folder content

Public void deletefile (File targetfile)
{< br> If (targetfile. isdirectory ()
{< br> file [] list = targetfile. listfiles ();
for (INT I = 0; I deletefile (list [I]);
}< br> //
targetfile. deleteonexit ();
}< br> else
targetfile. deleteonexit ();
}
