BHCluster is on a distinguished road
Problem with searching while using GUI
I have a program which takes in certain information from a user an does that perfect. My only problem is when I don't know how to do search for the certain flight id and then display all of the records in that search. Bellow I have enclosed the program and if anybody knows how to do this search please show me.


The code bellow compiles and runs ythe reason why I have included it is so you see what I am doing.
Code:


public class FlightReservationMain extends javax.swing.JPanel {
	private static javax.swing.JTable jTable;
	private javax.swing.JScrollPane jScrollPane;
	private javax.swing.JPanel jPanel1;
	private javax.swing.JPanel jPanel2;
	private javax.swing.JButton jButton1;
	private javax.swing.JButton jButton2;
	private javax.swing.JButton jButton3;
	private javax.swing.JButton jButton4;
	private javax.swing.JButton jButton5;
	private static int rowCnt = 0;
	private static int selectedRow;

	public FlightReservationMain() {
		jTable = new javax.swing.JTable(new AbstractTable());

		//Table Column size
		javax.swing.table.TableColumn column = null;
		for(int i = 0; i < 5; i++) {
			column = jTable.getColumnModel().getColumn(i);
			if (i == 0) {
				column.setPreferredWidth(10);
			} else if(i == 1) {
				column.setPreferredWidth(150);
			} else if(i == 3) {
				column.setPreferredWidth(100);
			} else {
				column.setPreferredWidth(100);
			}
		}

		jScrollPane = new javax.swing.JScrollPane(jTable);

		jPanel1 = new javax.swing.JPanel(new java.awt.BorderLayout());

		jPanel1.add(jScrollPane, java.awt.BorderLayout.CENTER);

		jButton1 = new javax.swing.JButton("Add Entry");
		jButton2 = new javax.swing.JButton("Update");
		jButton3 = new javax.swing.JButton("Delete");
		jButton4 = new javax.swing.JButton("Close");
		jButton5 = new javax.swing.JButton("Search");

		jPanel2 = new javax.swing.JPanel(new java.awt.FlowLayout());

		jPanel2.add(jButton1);
		jPanel2.add(jButton2);
		jPanel2.add(jButton3);
		jPanel2.add(jButton4);
		jPanel2.add(jButton5);

		jButton1.addActionListener(new java.awt.event.ActionListener() {
			public void actionPerformed(java.awt.event.ActionEvent e) {
				new AddEntry().setVisible(true);
			}
		});

		jButton2.addActionListener(new java.awt.event.ActionListener() {
			public void actionPerformed(java.awt.event.ActionEvent e) {
				new UpdateEntry(jTable.getValueAt(getSelectedRow(), 0).toString(),
								jTable.getValueAt(getSelectedRow(), 1).toString(),
								jTable.getValueAt(getSelectedRow(), 2).toString(),
								jTable.getValueAt(getSelectedRow(), 3).toString(),
								jTable.getValueAt(getSelectedRow(), 4).toString()).setVisible(true);
			}
		});

		jButton3.addActionListener(new java.awt.event.ActionListener() {
			public void actionPerformed(java.awt.event.ActionEvent e) {
				removeEntry();
			}
		});

		jButton4.addActionListener(new java.awt.event.ActionListener() {

				System.exit(0);
			}
		});

					public void actionPerformed(java.awt.event.ActionEvent e) {

					}
		});

		jPanel1.add(jPanel2, java.awt.BorderLayout.SOUTH);
		jPanel1.setPreferredSize(new java.awt.Dimension(750, 300));

		add(jPanel1);
	}

	public static void addEntry(FlightReservation flightReservation) {
		jTable.setValueAt(flightReservation.getFlightId(), rowCnt, 0);

	}

		new SearchFlight().setVisible(true);
	}
}
What I am trying to do is use the SearchFilight.java to access FlightReservationMain.java so it displays results back in SearchFlight. If anybody know how to do this please help.
Thank you

Code:
public class FlightReservationMain extends JPanel {
    FlightReservationMain enclosingClassRef = this;
    private static JTable jTable;
    private JButton jButton5;

public FlightReservationMain() {
    jButton5 = new JButton("Search");
    jButton5.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
            SearchFlight search = new SearchFlight();
            // call methods/access fields in search...
            // If the SearchFlight class needs a reference to this
            // enclosing class, viz, FlightReservationMain, you can
            // send a reference to it via a (new) constructor:
            SearchFlight search = new SearchFlight(enclosingClassRef);
            // Or if SearchFlight needs only a reference to the table
            // you can send a reference to it along in a constructor:
            SearchFlight search = new SearchFlight(jTable);
            // or perhaps in a method:
            search.setTable(jTable);
        }
    });
