File directory = new file ("");//parameter is empty
String coursefile = Directory.getcanonicalpath ();
System.out.println (Coursefile);

Result: C:\Documents and Settings\administrator\workspace\projectname

Third: Get the path of the Selected.txt file under the current Engineering src directory

URL Xmlpath = This.getclass (). getClassLoader (). GetResource ("Selected.txt");
System.out.println (Xmlpath);

Result: File:/c:/documents%20and%20settings/administrator/workspace/projectname/bin/selected.txt
