when i run this code on netbeans. but netbeans gives me this errors

Code:

---

Enter the URL address:
http://nscraps.com/images/logo.png

Exception in thread "main" java.lang.ClassCastException: sun.awt.image.URLImageSource cannot be cast to java.io.InputStream
        at javaassignment4.Main.getText(Main.java:67)
        at javaassignment4.Main.main(Main.java:17)
Java Result: 1

The error message is self explanatory. The Object returned by conn.getContent() is a sun.awt.image.URLImageSource, which can't be cast to java.io.InputStream.

db

i change somewhere and i got this result

run:
Enter the URL address:
nscraps.com/images/logo.png
Error - :no protocol: nscraps.com/images/logo.png

The error message says your URL does NOT have a protocol.
What do you think the protocol is on the URL you are using?

Do you know what a protocol is?
Have you read the API doc for the URL class?
