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.
The answer is C Excel. Excel allows you to make spreadsheets.
Hope this helps :-)
Answer:
29
Explanation:
for n=28:
--------------
Algorithm 1 performs f(n) = n2 + n/2 = 28*28 + 28/2 = 798
Algorithm 2 performs f(n) = 12*28 + 500 = 836
for n=29
--------------
Algorithm 1 performs f(n) = n2 + n/2 = 29*29 + 29/2 = 855.5
Algorithm 2 performs f(n) = 12*29 + 500 = 848
so, for n=29, algorithm 2 will be faster than algorithm 1
Answer:
if (x > 7 && Math.sqrt(x) < 3)
Explanation:
The previous condition checks if the square root of x is less than 3, but this would raise an error if x is a value equal to or less than 0.
So, the condition checks for the value of x before evaluating the square root after the AND operation to prevent an arithmetic exception.
