Multiple ways to get the current file path in Java

Public String Getclasspath () {

    String path="";

try {
Path=new File (GetClass (). getClassLoader (). GetResource (""). Touri ()). GetPath ();

 }catch (URISyntaxException ex) {}    return path;

}

Directory path when the program is run. The path where the program double-clicks or the bat file is located
System.getproperties ("User.dir");

The first type:
File F = new file (This.getclass (). GetResource ("/"). GetPath ());
System.out.println (f);

Results:
C:documents%20and%20settingsadministratorworkspaceprojectnamebin

Gets the project path where the current class is located;
If you do not add "/"
File F = new file (This.getclass (). GetResource (""). GetPath ());
System.out.println (f);

Results:
C:documents%20and%20settingsadministratorworkspaceprojectnamebincomtest

Gets the absolute path of the current class;

The second type:
File directory = new file ("");//parameter is empty
String coursefile = Directory.getcanonicalpath ();

System.out.println (Coursefile);
Results:
C:documents and Settingsadministratorworkspaceprojectname

Gets the project path where the current class is located;

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

Results:
file:/c:/documents%20and%
20settings/administrator/workspace/projectname/bin/selected.txt

Gets the path to the Selected.txt file in the current project SRC directory

The fourth type:
System.out.println (System.getproperty ("User.dir"));

Results:
C:documents and Settingsadministratorworkspaceprojectname

Get current project path

The fifth type:
System.out.println (System.getproperty ("Java.class.path"));

Results:
C:documents and Settingsadministratorworkspaceprojectnamebin

Get current project path

Absolute path and relative path:
The absolute path is the real path on the hard disk of the file or directory on your home page, (URL and physical path) for example: C:XYZ

Est.txt represents the absolute path to the Test.txt file. Http://www.111cn.net also represents a URL absolute

Path. Relative path: The path relative to a base directory. Contains the relative path to the web (relative to the directory in HTML)

, for example: In a servlet, "/" represents a directory of Web apps. and the relative representation of the physical path. For example: "./" Generation

Table current directory, ".. /"represents the parent directory. This similar representation also belongs to the relative path. In addition about the URI,

Url,urn and other content, please refer to the RFC related documentation standards. RFC 2396:uniform Resource Identifiers

(URI): Generic Syntax
