String[] hostList = { "http://crunchify.com", "http://yahoo.com",

for (int i = 0; i < hostList.length; i++) {
String url = hostList[i];
String status = getStatus(url);
System.out.println(url + "\t\tStatus:" + status);
}
}
public static String getStatus(String url) throws IOException {
String result = "";
try {
URL siteURL = new URL(url);
HttpURLConnection connection = (HttpURLConnection) siteURL
.openConnection();
connection.setRequestMethod("GET");
connection.connect();
int code = connection.getResponseCode();
if (code == 200) {
result = "Green";
}
} catch (Exception e) {
result = "->Red<-";
}
return result;
}
}Output:
