先看程序
public String GetFileChooser(String strExt,String strButton,boolean bSave)
{
JFileChooser jf = new JFileChooser(".");
jf.setFileSelectionMode(JFileChooser.FILES_AND_DIRECTORIES);
jf.setFileFilter(new javax.swing.filechooser.FileFilter()
{
public boolean accept(File f)
{
String filePath = f.getAbsoluteFile().toString().toUpperCase();
if (filePath.endsWith(strExt))
return true;
else
return false;
} public String getDescription()
{
return strExt;
}
});
jf.setApproveButtonText(strButton);
int result = -1;
if(bSave)
result = jf.showSaveDialog(null);
else
result = jf.showOpenDialog(null);
if(result == JFileChooser.APPROVE_OPTION)
return jf.getSelectedFile().getPath();
else
return null;
}程序指明是strExt变量出错,虽然知道错误的地方,但不知道该如何更正望指教

{
final String str = strExt;//加上这句.. 内部类要引用外部类的变量..该变量必须是final的.
JFileChooser jf = new JFileChooser(".");
jf.setFileSelectionMode(JFileChooser.FILES_AND_DIRECTORIES);
jf.setFileFilter(new javax.swing.filechooser.FileFilter() {
public boolean accept(File f) {
String filePath = f.getAbsoluteFile().toString().toUpperCase();
if (filePath.endsWith(str))
return true;
else
return false;
} public String getDescription() {
return str;
}
});
jf.setApproveButtonText(strButton);
int result = -1;
if (bSave)
result = jf.showSaveDialog(null);
else
result = jf.showOpenDialog(null);
if (result == JFileChooser.APPROVE_OPTION)
return jf.getSelectedFile().getPath();
else
return null;
}
}已经通过了..
