Storing input in a multi-dimensional array?

Posted by confused on September 26, 2001 at 8:26 AM

I'm a newbie to Java and I have a question regarding a program I am writing as a part of an asignment. I need to create a GUI to accept some input in two text fields, click on an "accept button" which calls a method store() to save that input into an array. I am having troubles with this store method and storing the input into the array. Can someone help with the code for the store method as it is driving me *crazy*. Thanks in advance. A data structure the array is created in Shop.java and Sales.java is the main program. The store method is at the bottom.

//Shop.java
public class Shop{
String Code;
double Qty;
//public Shop(){
//}
public Shop(String code, double qty){
Code = code;
Qty = qty;
}
String getCode(){
return Code;
}
String getAll(){
return Code + " " + Qty;
}
}

//Sales.java

public class Sales extends JPanel implements ActionListener{
JButton acceptB, displayB, totalB, exitB;
JTextField Code, Qty;
Shop purchase[][];
String TempDate;
List display;
int counter1 = 0;
int counter2 = 0;
String tempCode = "";
double tempQty = 0;
String Exit = "00";

public Sales(){

purchase = new Shop[100][100];

add(new JLabel("Product Code : "));
Code = new JTextField(" ", 15);
add(Code);
add(new JLabel("Quantity : "));
Qty = new JTextField(" ", 15);
add(Qty);
acceptB = new JButton("Accept");
acceptB.addActionListener(this);
add(acceptB);
displayB = new JButton("Display");
displayB.addActionListener(this);
add(displayB);
totalB = new JButton("Total");
totalB.addActionListener(this);
add(totalB);
exitB = new JButton("Exit");
exitB.addActionListener(this);
add(exitB);
display = new List();
add(display);
}

public void actionPerformed(ActionEvent e){
String what = e.getActionCommand();
if(what == "Accept"){
tempCode = Code.getText().trim();
tempQty = convert(Qty.getText());
store();
}
if(what == "Display"){
displayItem();
}
if(what == "Total"){
End_List();
}
if(what == "Exit"){
System.exit(0);
}
}

public void store(){
try{

//Problem coding this method

}catch(Exception et){System.out.println("Help");}
}
