dateConversionProblem

[newToJava]

Problem:
I need to read in any date( format 00/00/00 ) from a JTextField and
tokenize it into the day year month to be converted into ints to use in the
java date methods. I seperated my tokens fine and it works. I then created
a getDayToken(String) method to convert the tokens into ints( month, day,
year).

public int getDayToken( String gdt ){

int day;
StringTokenizer dayToken =
new StringTokenizer( gdt);
try {
while( dayToken.hasMoreTokens() );
{
dayToken.nextToken();
dayToken.nextToken();
}
}
catch( NoSuchElementException e )
{
System.out.println( e );
}
day = Integer.parseInt( dayToken );
return( day );
}

After the method is called the jdk1.3 compiler complains that a java.lang.string
can't be applied to a javax.swing.JTextField. are they
not both considered strings. I also can't convert a java.util StringTokenizer
object into a string using Integer.parseInt()compile says connot aresolve
symbol Integer.parseInt() If there is a conversion
COULD SOME ONE STEAR ME IN THE RIGHT DIRECTION PLEASE!!!!!!.

The full code to test my method is below:

import javax.swing.*;
import java.util.*;
import java.awt.*;
import java.awt.event.*;

public class TokenTest extends JFrame{

private JLabel prompt;
private JTextField input;
private JTextArea output;
public String stringTokenMonth, stringTokenDay, stringTokenYear;


public TokenTest()
{
super( "testing the Tokeniser" );

Container c = getContentPane();
c.setLayout( new FlowLayout() );

prompt = new JLabel(
"Enter a date and press enter: " );
c.add(prompt);

input = new JTextField( 20 );
input.addActionListener(
new ActionListener() {
public void actionPerformed( ActionEvent ae )
{
String delim = new String();

delim = "//";
String stringToTokenize = ae.getActionCommand();
StringTokenizer tokens =
new StringTokenizer( stringToTokenize, delim );

output.setText( "Number of Elements: " +
tokens.countTokens() +
"\nThe tokens are: \n" );

while( tokens.hasMoreTokens() ){
stringTokenMonth = tokens.nextToken();
stringTokenDay = tokens.nextToken();
stringTokenYear = tokens.nextToken();
}

output.append( stringTokenMonth + "\n" );
output.append( stringTokenDay + "\n" );
output.append( stringTokenYear + "\n" );

//Test method call
output.append("method getDayToken( String )\n" + getDayToken( input
) );
}
}
);

c.add( input );

output = new JTextArea( 10, 20 );
output.setEditable( false );
c.add( new JScrollPane( output ) );

setSize(275, 400 );
show();
}

public int getDayToken( String gdt ){

int day;



StringTokenizer dayToken =
new StringTokenizer( gdt);

try {
while( dayToken.hasMoreTokens() );
{
dayToken.nextToken();
dayToken.nextToken();
}
}

catch( NoSuchElementException e )
{
System.out.println( e );
}


day = Integer.parseInt( dayToken );
return( day );
}




public static void main( String args[] )

{
TokenTest app = new TokenTest();

app.addWindowListener(
new WindowAdapter() {
public void windowClosing( WindowEvent e )
{
System.exit( 0 );
}
}
);
}
}

Well first of all, you have done a lot of extra programming to convert a
String to a Date. The most straightforward way to do that is to create a
SimpleDateFormat object and use its parse() method to do this conversion:

SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yy");
Date result = sdf.parse(theString);

And if you want to put a String into a JTextField, you use its setText()
method.
