public static void main(String args[]) { <<ERROR HERE
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
new addcriminal().setVisible(true);

Looks to me like you forgot the closing curly bracket in your catch statement.
catch(SQLException ex) {
JOptionPane.showMessageDialog(null, ex.toString());
}
