-How to use put command in Java for dynamic field name creation

I have a requirement to create dynamic field name (based on value of a
column) at run time... I think this is the usual approach that we will
used in HBASE for one to many relationships..
For example, physical table has the following structure
*Branch Number* *Branch Name* *Supported Currency Code* *Currency Name* 1
ABC INR India Rupee 1 ABC USD US Dollar 2 EFG SGD Singapore Dollar 2 EFG
INR India Rupee
Row key is Branch Number...
To flatten it out, we have to redesign the HBASE table as follows :
The fields related to currency will be grouped and created under a single
field (supported currency code & currency name) and the field name is
dynamically created as "CCY"+<actual value for supported currency code>
For the above scenario, the HBASE table will look llike following...
*Branch Number* *Branch Name* *CCY_INR* *CCY_USD* *CCY_SGD* 1 ABC INR|India
Rupee USD|US Dollar
2 EFG INR|India Rupee
Now the question is,
what is the syntax for the put statement in JAVA so that the Column name is
put ('branch','1','cf1:'+'CCY'+<valueof currency field>,<value of currency
field>+<value of currency name field>);
the above sytax is not working for me...
Please let me know the syntax of the put statement in this scenario using
