java - read file, convert string to double, store in 2d array -

i need read list of numbers in file , store 2d array. have far. how go achieving goal?

//this part of code public class rainfall {      double[][] precip;      public rainfall()     {         precip = new double [5][12];     }      public void readfile(bufferedreader infile) throws ioexception     {         fileinputstream infile = new fileinputstream("numbers.dat");         bufferedreader br = new bufferedreader(new inputstreamreader(infile));          string[][] myarray = new string[5][12];         while (infile.readline() != null)          {                (int j = 0; j < 5; j++)             {                 (int = 0; < 12; i++)                 {                     myarray[j][i] = infile.readline();                 }              }           }         infile.close();     }

//is each number on new line? you're close, added few lines below.       public class rainfall  {      double[][] precip;      public rainfall()     {         precip = new double [5][12];     }      public void readfile(bufferedreader infile) throws ioexception     {         //fileinputstream infile = new fileinputstream("numbers.dat");         bufferedreader br = new bufferedreader(new filereader("numbers.dat"));         string line = "";         string[][] myarray = new string[5][12];          while ((line = br.readline()) != null)          {                double num = double.parsedouble(line.trim());             (int j = 0; j < 5; j++)             {                 (int = 0; < 12; i++)                 {                     precip[j][i] = num;                 }              }           }         br.close();     }
