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

thank you for the help!!

Solution

Hi, Please find my implemetation.
Please let me know in case of any issue.

public class Test {

  

   public static void main(String[] args) {

      

       // Hi you can take all inout in a line as String

       // and you can split input by space character (\' \')

       // and after that each individual entery: adain you can divide by \'/\' character

      

       String input = \"13/3 3/2 3/8 12/5 4/5\";

      

      

       String[] fractionsStr = input.split(\"\\\\s+\"); // split by space

      

       // now create numerator and denominator array of length fractionsStr

      

       int num_of_fraction = fractionsStr.length;

      

       int numerators[] = new int[num_of_fraction];

       int denominators[] = new int[num_of_fraction];

      

       // now iterate through fractionsStr and store numertors and denominators

       for(int i=0; i<num_of_fraction; i++){

          

           String fraction = fractionsStr[i];

          

           // split fraction by \'/\'

           String[] fractionT = fraction.split(\"/\");

          

           numerators[i] = Integer.parseInt(fractionT[0]);

           denominators[i] = Integer.parseInt(fractionT[1]);

       }

      

       //printing fraction

       for(int i= 0; i<num_of_fraction; i++){

           System.out.println(numerators[i]+\"/\"+denominators[i]);

       }

   }

  

}

/*

Output:

13/3

3/2

3/8

12/5

4/5
