In its simplest form, a resource bundle is represented by a text file containing keys and a
text value for each key.
17) What is transient variable?
Transient variable can't be serialize. For example if a variable is declared as transient in a

be written to the stream instead when the class is retrieved from the ObjectStream the
value of the variable becomes
null
