java例程练习（将string转成double)

public class Test { public static void main(String[] args) { String s = "1,2;3,4,5;6,7,8"; double [][] d; String [] sFirst = s.split(";"); d = new double[sFirst.length][]; for(int i = 0; i < sFirst.length; i++) { String [] sSecond = sFirst[i].split(","); d[i] = new double[sSecond.length]; for(int j = 0; j < sSecond.length; j++) { d[i][j] = Double.parseDouble(sSecond[j]); } } for(int i = 0; i < d.length;i++) { for(int j = 0; j < d[i].length; j++) { System.out.print(d[i][j] + " "); } System.out.println(); } } }
