regex to match substring after nth occurence of pipe character

Question

i am trying to build one regex expression for the below sample text in which i need to replace the bold text. So far i could achieve this much ((\\|))

Answer 1

Here's how you can do the replacement:

String input = "1.1|ProvCM|111111111111|10.15.194.25|10.100.10.3|10.100.10.1|docsis3.0";
int n = 3;
String newValue = "new value";
String output = input.replaceFirst("^((?:[^|]+\\|){"+n+"})[^|]+", "$1"+newValue);

This builds:

"1.1|ProvCM|111111111111|new value|10.100.10.3|10.100.10.1|docsis3.0"
