What delimiter is used to separate fields in the a. txt file?

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.

solution:

the auto-correct option of the auto-correct tool enables you to add and delete words that do not follow abbreviation rules because:

it is a feature that allows outlook to correct common spelling and typing errors and to replace characters with symbols. we can also can use auto-correct as a shortcut, which means we can type a small string of characters and have those characters replaced by a longer string.
