Ciao a tutti!! ho una stringa, recuperata da un DB fatta così:
codice:
1;2;;|;3;;|;;4;|;;;5|;;;6|;;5;
devo trasformarla in una matrice double[][] fatta così
codice:
1 2 0 0
0 3 0 0
0 0 4 0
0 0 0 5
0 0 0 6
0 0 5 0
ho creato una funzione così fatta
codice:
public static double[][] conversione2D(String a,String carattere,String car){
String array[] = a.split(car);
int misura = array.length;
System.out.println("La Z:" + misura);
System.out.println("Il carattere:" + carattere);
int misura2 =array[0].split(carattere).length;
System.out.println("La X:" + misura2);
double out[][] = new double[misura][misura2];
for(int i=0;i<misura;i++){
String x[] = array[i].split(carattere);
System.out.println("La lunghezza:" + x.length);
for(int j=0;j<x.length;j++){
if(!x[j].isEmpty()){
out[i][j] = Double.parseDouble(x[j]);
} else out[i][j]=0;
}
}
Ma non funziona, mi ritorna una ArrayIndexOutOfBoundsException,
codice:
Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: 2
