FileUtils.copyURLToFile Getting Stuck

I'm using a Jave program to get NSE share price data from NSE's website like this for example:

url = new URL("https://archives.nseindia.com/archives/equities/bhavcopy/pr/PR071122.zip");
f = new File("NSEData.zip");
try {
     FileUtils.copyURLToFile(url, f);
} catch (Exception e) {
}

The above code works for dates where market data exists, like 07/11/22 . However, where data does not exist, like on 08/11/22, the url is broken and the copyURLToFile line gets stuck indefinitely during runtime (replacing 071122 with 081122 in the url/code above will cause it to get stuck). Is there an easy way to get the program to recognize that the url for a certain date is broken (eg. https://archives.nseindia.com/archives/equities/bhavcopy/pr/PR081122.zip) and therefore ignore and continue past the try block without getting stuck?

My current workaround is to check whether a certain date is a market holiday using a DayOfWeek check as well as a HashSet containing a list of public holidays, but this is not perfect.

So, basically your URL is returning 500 error upon requesting for invalid date. You can simply use the another method available in FileUtils

https://commons.apache.org/proper/commons-io/javadocs/api-2.5/org/apache/commons/io/FileUtils.html#copyURLToFile(java.net.URL,%20java.io.File,%20int,%20int)

Example code : (Adjust timeouts as per your requirement)

var url = new URL("https://archives.nseindia.com/archives/equities/bhavcopy/pr/PR081122.zip");
    var f = new File("NSEData.zip");
    try {
        FileUtils.copyURLToFile(url, f, 5000, 5000);
    } catch (Exception e) {
    }
