How can I check if a URI displayed by java.awt.Desktop is blank or not

Question

I want to write a program that opens different URI's while changing a parameter. How can I check if the loaded page is blank or has data?

Answer 1

Not possible, since Desktop.browse(...) opens the systems default browser, which will be an external program. But you can use the URL class to open a connection to your URLs, and check if the underlying inputstream contains data (InputStream.available()).
