Splitting String in Java with empty elements

Question

I\'m reading from a .csv File line by line. One line could look for example as following: String str = \"10,1,,,,\".

Now I would like to split according to

Answer 1

split only drops trailing delimeters by default. You can turn this off with

String str = "9,,,1,,";
String[] parts = str.split(",", -1);
System.out.println(Arrays.toString(parts));

prints

[9, , , 1, , ]
