Java String split is not working

Question

Java Experts ,

Please look into the below split command code and let me know why last two nulls are not captured.

String test = \"1,O1,,,,0.0000,0.0000,         


        

Answer 1

split silently discards trailing separators, as specified in the Javadoc.

In general, the behavior of split is kind of weird. Consider using Guava's Splitter instead, which has somewhat more predictable and customizable behavior. (Disclosure: I contribute to Guava.)

Splitter.on(',').split("1,O1,,,,0.0000,0.0000,,");
// returns [1, O1, , , , 0.0000, 0.0000, , ]
Splitter.on(',').omitEmptyStrings()
  .split("1,O1,,,,0.0000,0.0000,,");
// returns [1, O1, 0.0000, 0.0000]
