I’m assuming the input is Java. To simply extract the values, you can do
String str = "rtt min/avg/max/mdev = 10.876/13.344/17.155/2.736 ms";
String[] strings = str.split(" "); // split string on spaces, 5 new strings
str = strings[3]; // select the 4th of these strings
strings = str.split("https://stackoverflow.com/"); // split again, this time on "https://stackoverflow.com/"
double min = Double.parseDouble(strings[0]);
double avg = Double.parseDouble(strings[1]);
double max = Double.parseDouble(strings[2]);
double deviation = Double.parseDouble(strings[3]);
Then remains to parse them as jsp and put them in a file. I hope this gets you started on the problem. (PS: I haven’t put the code in a method, as I don’t know exactly how you will be using it.)
