Estou iniciando no java e estava testando esse applet, s� que deu erro no
trecho abaixo:
****************************************************************************
*************************************************************************
chooser.setFileFilter(new
javax.swing.filechooser.FileFilter()
{ public boolean accept(File f)
{
return
f.getName().toLowerCase().endsWith(".gif");
}
});
****************************************************************************
*************************************************************************
D� esse erro abaixo
.java:66: <anonymous ImageViewer$1> should be declared abstract; it does not
define getDescription() in javax.swing.filechooser.FileFilter
{ public boolean accept(File f)
^
1 error
O que � ? O que tenho que fazer ?
Obs :Se eu tirar esse trecho do programa funciona...
Valeu...
