test whether a file exists

[DaveMere]

Hello all,

I'm developing an application designed to return records along with any associated images. The images will be named after the records primary key; ie "102.jpg". I'm going to display the full record information on one jsp and provide a link to another jsp to display the image, via a button/link whatever.

The problem is that not all records have associated images and I have to engineer the system such that the link appears ONLY when an image is present in the img directory. How can I test at runtime whether file 102.jpg is present?

Thanks!

File file = new File("images/102.jpg");

if (file.exists())
//file exists
