The following Java classes are examples of the Accumulo client API:
The Flush class will flush a table:
$ ./bin/runex client.Flush -c ./examples.conf -t trace
The RowOperations class demonstrates how to read and write rows using the BatchWriter and Scanner:

To create a table, write to it and read from it:
$ ./bin/runex client.ReadWriteExample -c ./examples.conf --createtable --create --read hello%00; datatypes:xml [LEVEL1|GROUP1] 1358192329450 false -> world hello%01; datatypes:xml [LEVEL1|GROUP1] 1358192329450 false -> world hello%02; datatypes:xml [LEVEL1|GROUP1] 1358192329450 false -> world hello%03; datatypes:xml [LEVEL1|GROUP1] 1358192329450 false -> world hello%04; datatypes:xml [LEVEL1|GROUP1] 1358192329450 false -> world hello%05; datatypes:xml [LEVEL1|GROUP1] 1358192329450 false -> world hello%06; datatypes:xml [LEVEL1|GROUP1] 1358192329450 false -> world hello%07; datatypes:xml [LEVEL1|GROUP1] 1358192329450 false -> world hello%08; datatypes:xml [LEVEL1|GROUP1] 1358192329450 false -> world hello%09; datatypes:xml [LEVEL1|GROUP1] 1358192329450 false -> world
