An array initializer can be used only when a new array reference is being
declared. For example, the following statement is a valid use of array
initializers:
String [] weekend = {“Saturday”, “Sunday”};
However, declaring the reference in one statement and assigning it to an
array initializer in another statement is not valid:
String [] weekend;
weekend = {“Saturday”, “Sunday”}; //Does not compile!
An array initializer can be used only when assigning it to a newly declared
array reference, all in a single statement.
