How to Read a URL's Content into a String in Java

Reading a URL's content into a string in Java can be a straightforward task, similar to its Groovy counterpart. Let's delve into the Java equivalent:

To achieve this in few lines of code, you can utilize Java's Scanner class:

<code class="java">String content = new Scanner(new URL(url).openStream()).useDelimiter("\A").next();</code>

This reads content from the provided URL and assigns it to the content variable.

If you prefer a more comprehensive implementation, consider the following:

<code class="java">public static String readStringFromURL(String url) throws IOException {
    try (Scanner scanner = new Scanner(new URL(requestURL).openStream())) {
        scanner.useDelimiter("\A");
        return scanner.hasNext() ? scanner.next() : "";
    }
}</code>

This function accepts a URL as an argument and handles exceptions with a try-with-resources block. It ensures proper resource cleanup after use.
