I tried to do a search system using java swing :
public void search(ActionEvent e){
String textEntered=getJTextField_searchField().getText();
if(textEntered.equals("")){
JOptionPane.showMessageDialog(null,"Please enter a word");
}
else{
kioskViewevents viewEvents=new kioskViewevents(textEntered);
if(viewEvents.searchContent() == true){
getJScrollPane().setVisible(false);
getJScrollPane_search();
}
else{
JOptionPane.showMessageDialog(null,"No result found");
}
}
}
This method will be perform after search button is on click. It will hide the previous table then replace with another table. Then I populate the search results inside the table.
public void SetUpJTable_search(){
DefaultTableModel tableModel = (DefaultTableModel) jTableSearch.getModel();
String[] data = new String[5];
db.setUp("IT Innovation Project");
String sql = "Select event_ID,event_Price,event_Title,event_Time,event_Date FROM crossEvent WHERE event_Title='"+ textEntered +"'";
ResultSet resultSet = null;
resultSet = db.readRequest(sql);
try {
while (resultSet.next()) {
data[0] = resultSet.getString("event_ID");
data[1] = resultSet.getString("event_Price");
data[2] = resultSet.getString("event_Title");
data[3] = resultSet.getString("event_Time");
data[4] = resultSet.getString("event_Date");
tableModel.addRow(data);
}
resultSet.close();
} catch (Exception e) {
System.out.println(e);
}
}
I set up my Search table :
private JTable getJTable_search() {
String header[] = { "Event ID", "Price", "Title","Time","Date"};
DefaultTableModel tableModel = (DefaultTableModel) jTable.getModel();
tableModel.setColumnIdentifiers(header);
jTableSearch.setAutoCreateColumnsFromModel(false);
jTableSearch.getColumnModel().getColumn(0).setMinWidth(100);
jTableSearch.getColumnModel().getColumn(0).setMaxWidth(100);
jTableSearch.getColumnModel().getColumn(1).setMinWidth(200);
jTableSearch.getColumnModel().getColumn(1).setMaxWidth(300);
jTableSearch.getColumnModel().getColumn(2).setMinWidth(300);
jTableSearch.getColumnModel().getColumn(2).setMaxWidth(400);
jTableSearch.getColumnModel().getColumn(3).setMinWidth(100);
jTableSearch.getColumnModel().getColumn(3).setMaxWidth(100);
jTableSearch.getColumnModel().getColumn(4).setMinWidth(100);
jTableSearch.getColumnModel().getColumn(4).setMaxWidth(100);
jTableSearch.getTableHeader().setFont(new Font("Dialog", Font.PLAIN, 20));
jTableSearch.getTableHeader().setForeground(Color.white);
jTableSearch.getTableHeader().setBackground(new Color(102, 102, 102));
jTableSearch.setRowHeight(50);
jTableSearch.setBounds(new Rectangle(97, 157, 800, 450));
jTableSearch.setFont(new Font("Dialog", Font.PLAIN, 18));
return jTableSearch;
}
My Scroll Pane for search table :
private JScrollPane getJScrollPane_search(){
if (jScrollPane_search == null) {
jScrollPane_search = new JScrollPane();
jScrollPane_search.setBounds(new Rectangle(75, 180, 800, 450));
jScrollPane_search.setViewportView(getJTable_search());
}
SetUpJTable_search();
return jScrollPane_search;
}
This whole junk of codes is to populate the table with data existing in database before performing search :
private JTable getJTable() {
String header[] = { "Event ID", "Price", "Title","Time","Date"};
DefaultTableModel tableModel = (DefaultTableModel) jTable.getModel();
tableModel.setColumnIdentifiers(header);
// Hide Topic ID
jTable.setAutoCreateColumnsFromModel(false);
jTable.getColumnModel().getColumn(0).setMinWidth(100);
jTable.getColumnModel().getColumn(0).setMaxWidth(100);
jTable.getColumnModel().getColumn(1).setMinWidth(200);
jTable.getColumnModel().getColumn(1).setMaxWidth(300);
jTable.getColumnModel().getColumn(2).setMinWidth(300);
jTable.getColumnModel().getColumn(2).setMaxWidth(400);
jTable.getColumnModel().getColumn(3).setMinWidth(100);
jTable.getColumnModel().getColumn(3).setMaxWidth(100);
jTable.getColumnModel().getColumn(4).setMinWidth(100);
jTable.getColumnModel().getColumn(4).setMaxWidth(100);
jTable.getTableHeader().setFont(new Font("Dialog", Font.PLAIN, 20));
jTable.getTableHeader().setForeground(Color.white);
jTable.getTableHeader().setBackground(new Color(102, 102, 102));
jTable.setRowHeight(50);
jTable.setBounds(new Rectangle(97, 157, 800, 450));
jTable.setFont(new Font("Dialog", Font.PLAIN, 18));
return jTable;
}
public void SetUpJTable() {
DefaultTableModel tableModel = (DefaultTableModel) jTable.getModel();
String[] data = new String[5];
db.setUp("IT Innovation Project");
String sql = "Select event_ID,event_Price,event_Title,event_Time,event_Date FROM crossEvent";
ResultSet resultSet = null;
resultSet = db.readRequest(sql);
tableModel.getDataVector().removeAllElements();
tableModel.fireTableDataChanged();
try {
while (resultSet.next()) {
data[0] = resultSet.getString("event_ID");
data[1] = resultSet.getString("event_Price");
data[2] = resultSet.getString("event_Title");
data[3] = resultSet.getString("event_Time");
data[4] = resultSet.getString("event_Date");
tableModel.addRow(data);
}
resultSet.close();
} catch (Exception e) {
System.out.println(e);
}
}
However, I got an error message which is :

Any guides? Thanks in advance.
Not sure which one is the line 158 in
ViewEvents.java(as you haven’t mentioned it), but the stacktrace and remaining code tells me that theArrayIndexOutOfBoundsexception is because you’re trying to access a column like below:And you don’t have those many columns in the
vectori.e.jTable.getColumnModel(). You’re trying to access an element beyond the size of the vector.The exact problem on why/where this issue occurs could be different, but this is where you should start looking at.
