Searching a collection
Hi all,
I am having trouble figuring out how to search a collection. The collection holds three strings (name, address, telephonenum) i would like to be able to search using a name as the search criteria.
public class estateGUI extends javax.swing.JFrame {
public estateGUI() {
initComponents(); }
public String name, address, telephonenum, find;
private void initComponents() {
addclient = new javax.swing.JButton();
findclient = new javax.swing.JButton();
logo = new javax.swing.JLabel();
cleartext = new javax.swing.JButton();
nametextfield = new javax.swing.JTextField();
addresstextfield = new javax.swing.JTextField();
numtextfield = new javax.swing.JTextField();
jLabel1 = new javax.swing.JLabel();
jLabel2 = new javax.swing.JLabel();
jLabel3 = new javax.swing.JLabel();
findnametextfield = new javax.swing.JTextField();
jLabel4 = new javax.swing.JLabel();
displaydetails = new javax.swing.JTextPane();
getContentPane().setLayout(new org.netbeans.lib.awtextra.AbsoluteLayout());
setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
setTitle("UWE Estates");
setCursor(new java.awt.Cursor(java.awt.Cursor.DEFAULT_CURSOR));
setMaximizedBounds(new java.awt.Rectangle(500, 500, 400, 420));
setName("MainFrame");
setResizable(false);
addWindowListener(new java.awt.event.WindowAdapter() {
public void windowClosing(java.awt.event.WindowEvent evt) {
exitForm(evt);
}
});
addclient.setText("Add Client");
addclient.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
addclientActionPerformed(evt);
}
});
getContentPane().add(addclient, new org.netbeans.lib.awtextra.AbsoluteConstraints(10, 210, 130, -1)); findclient.setText("FIND");
findclient.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
findclientActionPerformed(evt);
}
});
getContentPane().add(findclient, new org.netbeans.lib.awtextra.AbsoluteConstraints(170, 300, 90, -1));
logo.setBackground(new java.awt.Color(255, 255, 255));
logo.setFont(new java.awt.Font("Arial", 1, 24));
logo.setForeground(new java.awt.Color(51, 51, 255));

cleartextActionPerformed(evt);
}
});
getContentPane().add(cleartext, new org.netbeans.lib.awtextra.AbsoluteConstraints(270, 210, 130, -1));
nametextfield.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
nametextfieldActionPerformed(evt);
}
});
getContentPane().add(nametextfield, new org.netbeans.lib.awtextra.AbsoluteConstraints(140, 80, 130, -1));
addresstextfield.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {

}
});
getContentPane().add(addresstextfield, new org.netbeans.lib.awtextra.AbsoluteConstraints(140, 130, 130, -1));
numtextfield.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
numtextfieldActionPerformed(evt);
}
});
getContentPane().add(numtextfield, new org.netbeans.lib.awtextra.AbsoluteConstraints(140, 180, 130, -1));

getContentPane().add(jLabel2, new org.netbeans.lib.awtextra.AbsoluteConstraints(140, 110, 130, -1));
jLabel3.setHorizontalAlignment(javax.swing.SwingConstants.CENTER);
jLabel3.setText("Add Telephone Number");
getContentPane().add(jLabel3, new org.netbeans.lib.awtextra.AbsoluteConstraints(130, 160, 160, -1));
findnametextfield.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
findnametextfieldActionPerformed(evt);
}
});
getContentPane().add(findnametextfield, new org.netbeans.lib.awtextra.AbsoluteConstraints(90, 270, 260, -1));
jLabel4.setHorizontalAlignment(javax.swing.SwingConstants.CENTER);
jLabel4.setText("Input Name and Click Find");
getContentPane().add(jLabel4, new org.netbeans.lib.awtextra.AbsoluteConstraints(140, 250, 160, -1));
getContentPane().add(displaydetails, new org.netbeans.lib.awtextra.AbsoluteConstraints(90, 330, 260, 90));
pack();

private void findclientActionPerformed(java.awt.event.ActionEvent evt) {

}
private void addclientActionPerformed(java.awt.event.ActionEvent evt) {

branch newbranch = new branch();
newbranch.add(name, address, telephonenum);
} private void nametextfieldActionPerformed(java.awt.event.ActionEvent evt) {
}
private void exitForm(java.awt.event.WindowEvent evt) {
System.exit(0);
}
private void clearFields()
{
nametextfield.setText("");
addresstextfield.setText("");
numtextfield.setText("");
} public static void main(String args[])
{
new estateGUI().show();
}
private javax.swing.JButton addclient;
private javax.swing.JTextField addresstextfield;
private javax.swing.JButton cleartext;
private javax.swing.JTextPane displaydetails;
private javax.swing.JButton findclient;
private javax.swing.JTextField findnametextfield;
private javax.swing.JLabel jLabel1;
private javax.swing.JLabel jLabel2;
private javax.swing.JLabel jLabel3;
private javax.swing.JLabel jLabel4;
private javax.swing.JLabel logo;
private javax.swing.JTextField nametextfield;
private javax.swing.JTextField numtextfield;
}
Branch class that recieves input from estateGUI.
import javax.swing.*;
import java.awt.*;
import javax.swing.JOptionPane;
import java.awt.event.*;
public class branch {
public branch()
{}
public int customerID = 1;
public int maxclients = 5;
public int count;
private int index = 0;
public CustomerCollection clients = new CustomerCollection();
public void add(String name, String address, String telephonenum)
{
if (count < 2)
{
count++;
clients.addClient(name,address,telephonenum);
JOptionPane.showMessageDialog(null, "Client Stored \n" +name+ "\n"
+ address + "\n" + telephonenum);
}
else
{
JOptionPane.showMessageDialog(null, "Error. Maximum number of" +
"clients exceeded");
}
}
public void amend()
{}
public void delete()
{}
public void find(String details)
{
clients.findclient(details);
}
public void print()
{}
}
CustomerCollection class which builds the collection and has the method for add/find client etc:
import javax.swing.*;
import java.awt.*;
import javax.swing.JOptionPane;
import java.awt.event.*;
public class CustomerCollection
{
public Client[] collection;
private int arraySize = 5;
private int index = 0;
public CustomerCollection ()
{
collection = new Client[arraySize];
}
public void addClient (String name, String address,
String telephonenum)
{
if(index == collection.length)
{
collection[index] = new Client (name,address,telephonenum);
} index++;
}
public void findclient(String details)
{
}
Does anyone have any ideas on how i can find a specific client in a collection.
Thanks |
