Java split() method strips empty strings at the end?

we have a requirement like reading a file content and uploading the data to the database. the file content will be separated by delimiter ‘|’ like this

4000|name|state|city|zip||country|||address||

I can also have null values for certain column for which there is no data in between “|”. for example ‘||’ between zip and country. my problem is string.split(“//”,’|’) is taking the in between null values and returning array considering null values as an element. But the trailing ‘||’ after address is not being considered. As used in the example above, when i use string.split(“//”,’|’) i shd get an string array element of array size 11 but i get only 10.the last null is not getting retreived. Can anyone help with the solution?

Just use the regular split(String, int) method inside the String class:

String line = "4000|name|state|city|zip||country|||address||";
String data[] = line.split("\\|", -1); // escaped, because of regular expressions

The minus one is a convention that indicates that the string will be split as you want it.
