String array logic question with java I/O -

i need read line file: 5 chair 12.49 edit: want able have more lines of data.

i need separate each word/number different data types. first 1 int, second string, third double. need have them formatted this: item: chair price: $12.49 quantity: 5

now know how format, problem having parsing string elements respected data types (int, string, double).

i've tried:

string [] lines = lineinput.split(" "); for(string displaylines : lines) {     bufferedwriter.write(displaylines);     bufferedwriter.newline();     system.out.println(displaylines); } 

but separates each string new line , couldn't life of me figure out how have each line check if it's int, string or double.

then messing substring, couldn't work. thought of using mod % function , if:

if(lines.length % 2 == 0) {it's string};  

but work first line.

please believe me when i've tried on own , not making half-trying effort. giving up. stackoverflow, you're hope :(

if have lines format [int] [string] [double], can do:

string [] line = lineinput.split(" "); int x = integer.parseint(line[0]); string s = line[1]; double d = double.parsedouble(line[2]); 

you can modify necessary handle lines different formats.
