Java Tutorial |File Handling|Create,Read,Write and Delete
Create a File:
To create a file in Java, you can use the createNewFile() method. This method returns a boolean value: true if the file was successfully created, and false if the file already exists. Note that the method is enclosed in a try...catch block. This is necessary because it throws an IOException if an error occurs (if the file cannot be created for some reason).
To create a file in a specific directory (requires permission), specify the path of the file and use double backslashes
Write To a File:
We use the FileWriter class together with its write() method to write some text to the file
Read a File:
we use the Scanner class to read the contents of the text file
Delete a File:
To delete a file in Java, use the delete() method
