I mean, geotools base library should implement the methods getMax,

in fact, these methods are incomplete and runs well only in a few

Thanks Andrea.
Just to update this again...
Actually this is probably all you need to do if you are happy to read
the whole grid in to memory. It is using the underlying geotools
library from...geosolutions :) The code for getting the min and max
looks like it has just been moved from that class you were looking at
earlier.
import it.geosolutions.imageio.plugins.arcgrid.AsciiGridsImageReader;
import
it.geosolutions.imageio.plugins.arcgrid.spi.AsciiGridsImageReaderSpi;
.
.
.
file = new File("/path/to/your.asc");
AsciiGridsImageReader aa = new AsciiGridsImageReader(null);
aa.setInput(file);
// 0 is the index of the band you want to read...ASCII usually only
has one band anyway AFAIK
aa.read(0);
System.out.println(aa.getRasterReader().getMaxValue());
System.out.println(aa.getRasterReader().getMinValue());
System.out.println(aa.getRasterReader().getNoData());
it runs well!!!.
I have one more question but I will open other thread to talk about it.
Thanks a lot!!!
