JTableModel (Vector) upis u mySQL ?da li moze vrednost vector-a u koji smestim sve podatke iz modela direktno da se upise u mySQL,
ili mora da se radi konverzija u array (sto sam ja i radio na sledece nacine, ali bez uspeha):
Vector v = model.getDataVector(); // iz DefaultTableModel-a povlaci podatke
Code:
1.
v.trimToSize();
String[] s_array = new String[v.size()];
for (int i=0; i < s_array.length; i++)
{
s_array[i] = (String)v.elementAt(i);
System.out.println(s_array[i]);
}
Javlja gresku: Exception occurred during event dispatching:1.
v.trimToSize();
String[] s_array = new String[v.size()];
for (int i=0; i < s_array.length; i++)
{
s_array[i] = (String)v.elementAt(i);
System.out.println(s_array[i]);
}
java.lang.ClassCastException: java.util.Vector cannot be cast to java.lang.String
Code:
2.
String [] forms = new String[v.size()];
v.toArray(forms);
for (int i=0; i < forms.length; i++)
{
System.out.println(forms[i]);
}
Exception occurred during event dispatching:2.
String [] forms = new String[v.size()];
v.toArray(forms);
for (int i=0; i < forms.length; i++)
{
System.out.println(forms[i]);
}

Code:
3.
Object[] niz = v.toArray();
String[] forms = new String [ niz.length ];
System.arraycopy (niz, 0,
forms, 0,
forms.length );
Javlja gresku: Exception occurred during event dispatching:3.

String[] forms = new String [ niz.length ];

Every program is either trivial or it contains at least one bug.
