How to split a string on | (pipe) in Java [duplicate]

Answer 1

You'll have to escape your pipe character (split takes a regular expression as argument and therefore "|" is a control character):

str.split("\\|");

Please note: the resulting array contains an empty string at the beginning since you have "|" at start of your string.

Answer 2

You are using a special character and will have to escape it: str.split("\\|");

Answer 3

Use StringTokenizer..

String str="|serialNo|checkDelta?|checkFuture?|checkThis?|"
StringTokenizer st=new StringTokenizer(str,"|",false);
String s1 = st.nextToken();
String s2 = st.nextToken();
String s3 = st.nextToken();
String s4 = st.nextToken();

s1=serialNo

s2=checkDelta?

s3=checkFuture?

s4=checkThis?
