Final answer:
To read data from a URL in Java, use the open Stream() method on the URL object to get an Input Stream. Then, use an Input Stream Reader and Buffered Reader to read text from the Input Stream. Handle IO Exceptions appropriately and close the stream when done.
Step-by-step explanation:
To open a stream and read data from a URL using the URL object in Java, you can use the open Stream() method of the URL class. This method returns an Input Stream that can be read from. Below is an example of how you would use this method: Input Stream input Stream = url.open Stream(); You would then use an Input Stream Reader and possibly a Buffered Reader depending on your needs, to read from the Input Stream.
Buffered Reader reader = new Buffered Reader(new Input Stream Reader(input Stream)); String line; while ((line = reader. read Line()) != null) { = // Process the line}. Don't forget to handle IO Exceptions that could occur while working with I/O operations and to close the stream when done with reading the data to avoid resource leaks.
