How to filter arraylist results in servlet-jsp/jsp-servlet?

[Alok Sharma ji]

hello friends in my project i have an arraylist showing results in a jsp page table of given contents of database, i want to add a filter to it to show only the matched contents from list,

the table which is coming out is as:
student_id class_id student_name
1x0001 10 Ashish
1x2001 11 Anurag
1x2002 11 Arpit
1x0001 10 Alok

.............going on...

but i want the result to display page only for class_id::11 and remove other results how to do that?

greatest things can be achieved with small but innocent ideas :)

easy.. i think you're setting the table via a TableModel:

new AbstractTableModel() {
public String getColumnName(int col) {
return columnNames[col].toString();
}

public int getRowCount() { return rowData.length; }

public int getColumnCount() { return columnNames.length; }

public Object getValueAt(int row, int col) {
    return rowData\[row\]\[col\];
}

public boolean isCellEditable(int row, int col)
    { return true; }

public void setValueAt(Object value, int row, int col) {
    rowData\[row\]\[col\] = value;
    fireTableCellUpdated(row, col);
}

}

- While filling the table you can select the rows to be added to the table by a simple mechanism. This would not modify the ArrayList. - Also you can set up a filtered, temporary ArrayList and give that one to the table. - check this filtering @ oracle.com JAVA tutorials Choose your way and keep things easy (comments help...) regards, Torsten

I never finish anyth...

well just to be clear, this question is not related to swing its related to servlet J2EE, A very similar example of my case is here link[^] which is returning only names and id of people but in my case its name ,id, class id thus i have to filter the data as per my needs, anyways i am going to see the arraylist sorting method in your given link.
