Question

Write a class that will parse the path to a file. A file path describes the location that a file is on a computer. For example, take the following path: C:UsersBobDesktopexample.txt This path is saying that on the C drive, there is a folder named ‘Users’. In that ‘Users’ folder there is a folder called ‘Bob, in there is a folder called ‘Desktop’, and in the ‘Desktop’ folder there is a file called ‘example.txt’. You need to write a class called FilePath that has the following methods.

public class FilePath

{

      // Field

private String path;

// The path variable will be something like this:

// C:UsersBobDesktopexample.txt

public FilePath(String p)

// Returns the name of the drive that the file is on.

// ex. The drive of the path C:UsersBobDesktopexample.txt is C

// ex. The drive of the path MyDrive:UsersBobDesktopexample.txt is MyDrive

public String getDrive()

// Returns the name of the file, including the extension

// ex. The name of the file at C:UsersBobDesktopexample.txt is example.txt

// ex. The name of the file at MyDrive:WindowsSystem32calc.exe is calc.exe

public String getFileName()

// Returns the name of the file extension

// ex. The file extension for C:UsersBobDesktopexample.txt is txt

// ex. The file extension for MyDrive:WindowsSystem32calc.exe is exe

// ex. The file extension for E:documentsrchive.tar.gz is gz

public String getFileExtension()

// Returns the name of the file without the any extensions

// ex. The file base name for C:UsersBobDesktopexample.txt is example

// ex. The file base name for MyDrive:WindowsSystem32calc.exe is calc

// ex. The file base name for E:documentsrchive.tar.gz is archive

public String getBaseName()

// Returns the path to the folder that the file is in

// ex. Absolute path for C:UsersBobDesktopexample.txt is C:UsersBobDesktop

// ex. Absolute path for MyDrive:log.txt is MyDrive:

// ex. Absolute path for E:documentsrchive.tar.gz is E:documents

public String getAbsolutePath()

}

Create a tester class which creates a FilePath object, and print all the information about it out. Use the string C:\Users\Bob\Desktop\example.txt to test your code.

Please write in Java and at a simple level

}

// Returns the name of the drive that the file is on.

// ex. The drive of the path C:UsersBobDesktopexample.txt is C

// ex. The drive of the path MyDrive:UsersBobDesktopexample.txt is MyDrive

public String getDrive()
{
int index = path.indexOf(':');
return path.substring(0, index);
}

// Returns the name of the file, including the extension

// ex. The name of the file at C:UsersBobDesktopexample.txt is example.txt

// ex. The name of the file at MyDrive:WindowsSystem32calc.exe is calc.exe

public String getFileName()
{
int index = path.lastIndexOf("\");
return path.substring(index + 1);
}

// Returns the name of the file extension

// ex. The file extension for C:UsersBobDesktopexample.txt is txt

// ex. The file extension for MyDrive:WindowsSystem32calc.exe is exe

// ex. The file extension for E:documentsrchive.tar.gz is gz

public String getFileExtension()
{
int index = path.lastIndexOf(".");
return path.substring(index + 1);
}

// Returns the name of the file without the any extensions

// ex. The file base name for C:UsersBobDesktopexample.txt is example

// ex. The file base name for MyDrive:WindowsSystem32calc.exe is calc

public String getBaseName()
{
int index1 = path.lastIndexOf("\");
int index2 = path.lastIndexOf(".");

return path.substring(index1 + 1, index2);
}

// Returns the path to the folder that the file is in

// ex. Absolute path for C:UsersBobDesktopexample.txt is C:UsersBobDesktop

// ex. Absolute path for MyDrive:log.txt is MyDrive:

// ex. Absolute path for E:documentsrchive.tar.gz is E:documents

public String getAbsolutePath()
{
int index = path.lastIndexOf("\");
return path.substring(0, index);
}

}

TestFilePath.java
========

public class TestFilePath {
public static void main(String[] args) {

String path = "C:\Users\Bob\Desktop\example.txt";

System.out.println("Testing for path " + path);
FilePath p = new FilePath(path);
System.out.println("Drive=> " + p.getDrive());
System.out.println("Filename=> " + p.getFileName());
System.out.println("File extension=> " +p.getFileExtension());
System.out.println("Base name=> " + p.getBaseName());
System.out.println("Absolute path=> " + p.getAbsolutePath());

}
}

output
----
Testing for path C:UsersBobDesktopexample.txt
Drive=> C
Filename=> example.txt
File extension=> txt
Base name=> example
Absolute path=> C:UsersBobDesktop
