Whenever the data is need to be stored, a file is used
to store the data. File is a collection of stored
information that are arranged in string, rows, columns and lines etc.
In this section, we will see how to create a file. This example takes the file name and text data for storing to the file.
For creating a new file File.createNewFile( ) method is used. This method returns a boolean value true if the file is created otherwise return false. If the mentioned file for the specified directory is already exist then the createNewFile() method returns the false otherwise the method creates the mentioned file and return true.
Lets see an example that checks the existence of
a specified file.
First, this program checks, the specified file "myfile.txt" is exist or not. if it does not exist then a new file is created with same name to the current location.
Output of the Program
New file "myfile.txt" has been created to the current directory
If you try to run this program again then after checking the existence of the file, it will not be created and you will see a message as shown in the output.
The specified file is already exist
