java split string with regex and store it in variables

Question

I have a file and i have to read it line by line. The file contains similar lines, like these:

asd@lol kek|1.1.1.1 title@content m e s s a g e|2.3.4.5

I read these lines to String variables. How can i split these strings to other variables? For example: var1=title, var2=content, var3=m e s s a g e, var4=2.3.4.5

I tried something like this, but i cant find the solution:

stringArray=line.split("|");

You need to clearly identify your delimiters. Your desired result even is inconsistent, sometimes the space causes a split and sometimes it doesn't. — Kevin Bowersox

String has split method. Read its documentation and check its overloaded versions (especially split(regex,limit)). You can also take a look at Pattern and Matcher classes. — Pshemo

You can use this regex for matching and grab the captured groups:

^([^@]+)@(\S+)\s([^|]+)\|(.*)$

I suggest you read up a bit on difference between split and match operations.
