How do i read fractions off a string input in java?

i want the user to input a string of fractions say

\"13/3 3/2 3/8 12/5 4/5\"

i want to read these fractions and store them into an array int if possible, and get the total count of fractions inputed.

in this case count = 5

array[0] = 13/3

or array[0] =13 array[1]=/ array[2] =3

i'm not sure.. i'm kinda lost..

please show me in code
