Groovy provides a number of helper methods when working with I/O. Groovy provides easier classes to provide the following functionalities for files.
- Reading files
- Writing to files
- Traversing file trees
- Reading and writing data objects to files
In addition to this, you can always use the normal Java classes listed below for File I/O operations.
- java.io.File
- java.io.InputStream
- java.io.OutputStream
- java.io.Reader
- java.io.Writer
Reading files
The following example will output all the lines of a text file in Groovy. The method eachLine is in-built in the File class in Groovy for the purpose of ensuring that each line of the text file is read.
The File class is used to instantiate a new object which takes the file name as the parameter. It then takes the function of eachLine, puts it to a variable called line and prints it accordingly.
If the file contains the following lines, they will be printed.
Reading the Contents of a File as an Entire String
If you want to get the entire contents of the file as a string, you can use the text property of the file class. The following example shows how this can be done.
If the file contains the following lines, they will be printed.
Writing to Files
If you want to write to files, you need to use the writer class to output text to a file. The following example shows how this can be done.
If you open the file Example.txt, you will see the words “Hello World” printed to the file.
Getting the Size of a File
If you want to get the size of the file one can use the length property of the file class to get the size of the file. The following example shows how this can be done.
The above code would show the size of the file in bytes.
Testing if a File is a Directory
If you want to see if a path is a file or a directory, one can use the isFile and isDirectory option of the File class. The following example shows how this can be done.
The above code would show the following output −
Creating a Directory
If you want to create a new directory you can use the mkdir function of the File class. The following example shows how this can be done.
The directory E:Directory will be created if it does not exist.
Deleting a File
If you want to delete a file you can use the delete function of the File class. The following example shows how this can be done.
The file will be deleted if it exists.
Copying files
Groovy also provides the functionality to copy the contents from one file to another. The following example shows how this can be done.
The file Example1.txt will be created and all of the contents of the file Example.txt will be copied to this file.
Getting Directory Contents
Groovy also provides the functionality to list the drives and files in a drive.
The following example shows how the drives on a machine can be displayed by using the listRoots function of the File class.
Depending on the drives available on your machine, the output could vary. On a standard machine the output would be similar to the following one −
