How to test internet speed (JavaSE)?

Question

Is there a way to test internet speed using Java code?

For instance, like how we actually test with cmd command, ping command.

Answer 1

Look here on howto ping in java:

As the other dude said it is not a perfect solution I looked into our codebase because I knew we do something with ICMP packets here's what we use:

It does mean you'll have to compile a bit of JNI C to have access to a rawsocket (win32 and linux) are supported.

But you should look into a few more things to get a propper idea of internet speed:

• check the amount of connections possible in 10 secs
• check how long it takes to download a 5MB file
• check how long it takes to upload a 5MB file

that in combination with a few pings should give you quite a good impression of bandwidth and latency

Answer 2

use JSpeedTest Library

SpeedTestSocket speedTestSocket = new SpeedTestSocket();

// add a listener to wait for speedtest completion and progress
speedTestSocket.addSpeedTestListener(new ISpeedTestListener() {

    @Override
    public void onCompletion(SpeedTestReport report) {
        // called when download/upload is complete
        System.out.println("[COMPLETED] rate in octet/s : " + report.getTransferRateOctet());
        System.out.println("[COMPLETED] rate in bit/s   : " + report.getTransferRateBit());
    }

    @Override
    public void onError(SpeedTestError speedTestError, String errorMessage) {
         // called when a download/upload error occur
    }

    @Override
    public void onProgress(float percent, SpeedTestReport report) {
        // called to notify download/upload progress
        System.out.println("[PROGRESS] progress : " + percent + "%");
        System.out.println("[PROGRESS] rate in octet/s : " + report.getTransferRateOctet());
        System.out.println("[PROGRESS] rate in bit/s   : " + report.getTransferRateBit());
    }
});
