Turn string values into 2d array of type double

Question

I have a string:

String stringProfile = \"0,4.28 10,4.93 20,3.75\";

I am trying to turn it into an array like as follows:

d         


        

Answer 1

What about something like this:

Arrays.stream("0,4.28 10,4.93 20,3.75".split(" ")) //Stream
     .map(s -> 
           Arrays.stream(s.split(",")) // take an individual string like 0,4.28  
                 .map(Double::parseDouble) // and transform it to a double array
                 .toArray(Double[]::new)
      )
     .toArray(Double[][]::new);

the result is

$8 ==> Double[3][] { 
        Double[2] { 0.0, 4.28 }, 
        Double[2] { 10.0, 4.93 }, 
        Double[2] { 20.0, 3.75 } 
}
