    第一种:

    System.out.println(f); 
    结果: 
    C:Documents%20and%20SettingsAdministratorworkspaceprojectNamein 
    获取当前类的所在工程路径; 


    如果不加“/” 
    File f = new File(this.getClass().getResource("").getPath()); 
    System.out.println(f); 
    结果: 
    C:Documents%20and%20SettingsAdministratorworkspaceprojectNameincom est 
    获取当前类的绝对路径; 

    第二种:
    File directory = new File("");//参数为空 
    String courseFile = directory.getCanonicalPath() ; 
    System.out.println(courseFile); 
    结果: 
    C:Documents and SettingsAdministratorworkspaceprojectName 
    获取当前类的所在工程路径; 

    第三种: 
    URL xmlpath = this.getClass().getClassLoader().getResource("selected.txt"); 
    System.out.println(xmlpath); 
    结果: 
    file:/C:/Documents%20and%20Settings/Administrator/workspace/projectName/bin/selected.txt 
    获取当前工程src目录下selected.txt文件的路径 

    第四种: 
    System.out.println(System.getProperty("user.dir")); 
    结果: 
    C:Documents and SettingsAdministratorworkspaceprojectName 
    获取当前工程路径 

    第五种: 
    System.out.println( System.getProperty("java.class.path"));
