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.
