Fleming,
Of course there is!
Look at some of the different methods in Result that return various Maps
in different format. For your example, you might do:
=======
HTable table = new HTable("Table1");
Get g = new Get(Bytes.toBytes("Key1"));
Result r = table.get(g);
// Get a Map<qualifier,value> for Family
Map<byte[],byte[]> family = r.getFamilyMap(Bytes.toBytes("Family"));
// You can get a value knowing the qualifier
byte [] value1 = family.get(Bytes.toBytes("qualifier1"));
// Or you can just iterate all the qualifiers and values
for(Map.Entry<byte[],byte[]> entry : family.entrySet()) {
byte [] qualifier = entry.getKey();
byte [] value = entry.getValue();
}
=======
All the maps that are returned by Result are NavigableMaps, so they are
sorted and allow a number of operations on them.
Hope that helps.

Hi there,
I have a table "Table1" with one Family and 10 qualifier.
Any ways that I can get these qualifier's name in Table1,
then I can loop qualifier collection to fetch each qualifier's value.
Thank you
Fleming
====================================================================================
HTable table = new HTable(config, "Table1");
Get g = new Get(Bytes.toBytes("Key1"));
Result r = table.get(g);
byte [] value1 = r.getValue(Bytes.toBytes("Family"),
Bytes.toBytes("qualifier1"));
String valueStr1 = Bytes.toString(value1);
byte [] value2 = r.getValue(Bytes.toBytes("Family"),
Bytes.toBytes("qualifier2"));
String valueStr2 = Bytes.toString(value2);
.
.
.
byte [] value10 = r.getValue(Bytes.toBytes("Family"),
Bytes.toBytes("qualifier10"));
String valueStr10 = Bytes.toString(value10);
