How to Efficiently Read URL Content in Java?

Simplified Java Implementation for Reading URL Content

Unlike Groovy, Java offers a more verbose approach for extracting text content from a URL. To address this, we present two efficient solutions using Java's built-in Scanner class.

Firstly, a single-line option:

<code class="java">String out = new Scanner(new URL("http://www.google.com").openStream(), "UTF-8").useDelimiter("\A").next();</code>

For a slightly expanded version:

<code class="java">public static String readStringFromURL(String requestURL) throws IOException {
    try (Scanner scanner = new Scanner(new URL(requestURL).openStream(), StandardCharsets.UTF_8.toString())) {
        scanner.useDelimiter("\A");
        return scanner.hasNext() ? scanner.next() : "";
    }
}</code>

Both options provide a concise and efficient method for retrieving URL content as a string, without the burden of complex stream handling.
