Witam
posiada taki kod
kod ma za zadanie odczytać dane spilt oraz zwinąć linijkę stringu w menu
z kodem
.....
as[k] = (String)vector.elementAt(k);
....
program kompiluje bez problemu ale nie zwija wierszy, natomiast
.............
as[k] = ((spilt_m)vector.elementAt(k)).string;
....................
program się kompiluje ale wyskakuje błąd

jaką komendę dodać do menu append, żeby funkcja
as[k] = ((spilt_m)vector.elementAt(k)).string;
zadziałała
podaje kod
public class spilt_m
{
public String string;
private Vector vector_a;
public spilt_m(String string1, spilt_m aw[])
{
string = string1;
if(aw != null && aw.length > 0)
{
vector_a = new Vector(aw.length);
for(int l = 0; l < aw.length; l++)
{
spilt_m w1 = aw[l];
vector_a.addElement(w1);
}
}
}
public static String[] split(String s, String s1)
{
Vector vector = new Vector();
String s2 = new String(s);
for(int i = s2.indexOf(s1); i >= 0; i = s2.indexOf(s1))
{
vector.addElement(s2.substring(0, i));
s2 = s2.substring(i + s1.length());
}
vector.addElement(s2);
String as[] = new String[vector.size()];
if(as.length > 0)
{
for(int k = 0; k < vector.size(); k++)
as[k] = (String)vector.elementAt(k); <====w tym miejcu jak napiszę as[k] = ((spilt_m)vector.elementAt(k)).string;
}
return as;
}
}
dziękuje
to są moje początki
