How do I check if a file exists in Java?

itemprop="text">

How can I check whether a file exists,
before opening it for reading in Java? (equivalent of Perl's -e
$filename).

The only href="https://stackoverflow.com/questions/1237235/check-file-exists-java">similar
question on SO deals with writing the file and was thus answered using
FileWriter which is obviously not applicable
here.

If possible I'd prefer a real API call
returning true/false as opposed to some "Call API to open a file and catch when it
throws an exception which you check for 'no file' in text", but I can live with the
latter.

Using href="https://docs.oracle.com/javase/9/docs/api/java/io/File.html"
rel="noreferrer">java.io.File:

File
            f = new File(filePathString);
if(f.exists() && !f.isDirectory()) {
            
 // do something
}
