Hi all.

I am getting java.lang.UnsupportedOperationException while storing the data into arraylist from database.

My code is....




public List displayNotice() throws SQLException, ClassNotFoundException
{

Class.forName("com.mysql.jdbc.Driver");
Connection con1=DriverManager.getConnection("jdbc:mysql://localhost:3306/mydatabase","root","root");

Statement st=con1.createStatement();
ResultSet rs=st.executeQuery("select noticedate, notice from mytable");
while(rs.next())
{
Notice note = new Notice();
note.setToday(rs.getString(1));
note.setEditor(rs.getString(2));



try
{
arrList.add(note);


}catch(Exception e)
{
e.printStackTrace();
}
return arrList;

}



It showing the above exception for add() fuction, due to which I am not able to get the data from database.

Help Please...

So what is your List object it doesn't support the "add" method?
Where are you getting the value of arrList from?
