Question
I have lines in an ASCII text file that I need to parse. The columns are separated by a variable number of spaces, for instance:
column1 column2 column3
How would i split this line to return an array of only the values?
thanks
Solution
String testvar = "Some Data separated by whitespace";
String[] vals = testvar.split("\\s+");
\s
means a whitespace character, the +
means 1 or more. .split()
splits a string into parts divided by the specified delimiter (in this case 1 or more whitespace characters).
OTHER TIPS
sed 's/ */\n/g' < input
Two spaces there btw.
Check the StringTokenizer class.
