JFrame application

Hi, My JFrame application is almost complete but I have one idea that I would like to implement.

How can I keep the last 5 open file in the menu bar?

if I click on one of the las open file it should be able to open? can Java do that?

Thank You

OBCT, Thanks for the link,

I thought it would be easier than that,

is the another wayx

Have you considered my way?

copy and paste that class where necessary, then here's an example of it being used:

...
String filename = "a file name and location";

LastFive lf = new LastFive();
lf.add( filename );
lf.add( "another filename" );
...
ObjectOutputStream out = new ObjectOutputStream( new FileOutputStream( "saveFile.ser" ) ); // Save to file
out.writeObject( lf ); //
out.close(); //

Then, later on, to load it back up, use this:

...
ObjectInputStream in = new ObjectInputStream( new FileInputStream( "saveFile.ser" ) );
LastFive lf = (LastFive) in.readObject();

String [] lastFive = new String [5];
for ( int i = 0; i < 5; i++ )
{
lastFive[i] = lf.getFile( i );
if ( lastFive[i] == "" )
break;
}
...

I hope that helps..?

Regards;

By the way, to save you scrolling back up again, here's the class you'd require for my idea:

class LastFive implements Serializable
{
String [] files = new String [5];

public LastFive()
{
for ( int i = 0; i < files.length; i++ )
{
files [i] = "";
}
}

public void add( String filename )
{
for ( int i = 0; i < files.lengthl i++ )
{
if ( files [i] == "" )
files [i] = filename;
else if ( i == 5 && files[i] != "" )
files[0] = filename;
}
}

public String getFile( int index )
{
return files[index];
}
}

Okay, fair enough. Could you post the code that you've done so far? Then I'll implement my idea into it for you?
