sorting and filtering in jcombobox binded with database in netbeans

[Neha Kaushik]

hello...
i hava a problem in sorting and filtering in jcombobox binded with database in netbeans . i have done binding of this jcombobox with database table using netbeans.
that jcombobox contains department names in it. now i want to show this jcombobox data sorted in ascending order.
i also want autosuggestion in it.
for eg
Press "T" -> It will drop-down display everything beginning with "T"

Press "i" -> It will drop-down display everything that begins with "Ti"

Press "m" -> It will drop down display everything that has "Tim" at the beginning.

here is my code which i tried...

private void sort(){
ComboBoxModel Lmodel = comboDeprtmnt.getModel();
List list = new ArrayList<>();

for(int i= 0 ; i <comboDeprtmnt.getItemCount() ; i++)
{
String obj = (Lmodel.getElementAt(i).toString());
char[] arr = obj.toCharArray();
list.add(obj);
Arrays.sort(arr);
System.out.println(list);

Arrays.binarySearch(arr, c);
}

}

i get the character as...
char c;
private void comboDeprtmntKeyReleased(java.awt.event.KeyEvent evt) {
c= evt.getKeyChar();

}



please help i am new in java ...
