"`java
String url = "https://www.example.com";
String proxyIp = "123.45.67.89";
int proxyPort = 8080;

Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(proxyIp, proxyPort));
URLConnection connection = new URL(url).openConnection(proxy);

// Set the proxy ip
connection.setRequestProperty("User-Agent", "Mozilla/5.0");

// Initiate the request
InputStream in = connection.getInputStream();
// Read the data
// …
