Example:

Let’s try to understand the code:

1. Creating the temp file:

As mentioned at the top, first we need to create a temporary file using below code.

2. Usage of ‘exists’ method:

Once the file has been created, we are going to use ‘exists‘ method of Java-IO library. It will test whether the file is present or not and based on the output, it will throw ‘pass‘ or ‘fail‘ in return.

3. Additional check after deleting the file:

Now, by using below line of code, we are deleting the created file and performing the file existence check again.

Lets run the above specified ‘CheckIfFileExists’ class.

That’s it, it’s that simple to check if File exists in Java 🙂
