Question

I have a text file which contains data seperated by ‘|’. I need to get each field(seperated by ‘|’) and process it. The text file can be shown as below :

ABC|DEF||FGHT

I am using string tokenizer(JDK 1.4) for getting each field value. Now the problem is, I should get an empty string after DEF.However, I am not getting the empty space between DEF & FGHT.

My result should be – ABC,DEF,””,FGHT but I am getting ABC,DEF,FGHT

Answer 1

From StringTokenizer documentation :

StringTokenizer is a legacy class that
is retained for compatibility reasons
although its use is discouraged in new
code. It is recommended that anyone
seeking this functionality use the
split method of String or the
java.util.regex package instead.

The following code should work :

String s = "ABC|DEF||FGHT";
String[] r = s.split("\\|");
