Java read CSV File 📰
IMPORTANT NOTE: If values in your CSV contain commas naturally, they will be split. (Ex. $1,000). If this is the case, replace:
String[] row = line.split(",");
with
String[] row = line.split(",(?=([^\"]*\"[^\"]*\")*[^\"]*$)");
^ This is regex and is very complicated. It looks for string patterns. Explaining this requires another video entirely.
