Answer:
The delimiter use is "::".
Explanation:
The Java inbuilt String.split( ) function is use to split a String into an array of String.
The split( ) takes delimiter as arguments/parameter which determines at which point the string is to be broken down into different part/token.
From the above code snippet;
Each line in the file a.txt that is not null is splitted using the statement below:
String[ ] v = line.split("::");
The line is splitted using "::" as delimiter and the resulting array is then assigned to the variable 'v'.
For instance, a line in the file could take the form:
John::Smith::Music
When it is splitted,
String lname = John;
because lname make reference to index 0 of the array.
String fname = Smith;
because fname make reference to index 1 of the array.
String dept = Music;
and dept make reference to index 2 of the array.
