I have such a line:
176.32.37.27:777754.38.156.202:777751.68.208.5:7777
How can the cycle inferred from this string of IP ports by using the split function or similar? To make it so:
176.32.37.27:7777 54.38.156.202:7777 51.68.208.5:7777
the ports are the same only because they have 4 digits
Since you know your port's length will always be 4, you can split based on a lookbehind that takes the colon and 4 digits:
String test = "176.32.37.27:777754.38.156.202:777751.68.208.5:7777";
System.out.println(
Arrays.toString(
test.split("(?<=:\\d{4})")
)
);
Output
[176.32.37.27:7777, 54.38.156.202:7777, 51.68.208.5:7777]

You can use the below code for split the IP Address.
String str = "176.32.37.27:777754.38.156.202:777751.68.208.5:7777";
String ipAdds[] = str.split("(?<=:\\d{4})");
for (String ipAdd: ipAdds)
System.out.println(ipAdd);
