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.

Answer:
Explanation:
The system will be deadlock free if the below two conditions holds :
Proof below:
Suppose N = Summation of all Need(i), A = Addition of all Allocation(i), M = Addition of all Max(i). Use contradiction to prove.
Suppose this system isn't deadlock free. If a deadlock state exists, then A = m due to the fact that there's only one kind of resource and resources can be requested and released only one at a time.
Condition B, N + A equals M < m + n. Equals N + m < m + n. And we get N < n. It means that at least one process i that Need(i) = 0.
Condition A, Pi can let out at least 1 resource. So there will be n-1 processes sharing m resources now, Condition a and b still hold. In respect to the argument, No process will wait forever or permanently, so there's no deadlock.
Technology has impacted society and education throughout history by helping save more lives and distroying them. I think the innovation that has had the most profound on education is being able to connect with teachers to better help us understand even we are not in school like what I am doing right now.
