To print the last element in the array named ar, you can write :A. System.out.println(ar.length);
timofeeve [1]

Answer:

Option (d) is the correct answer.

Explanation:

An Array is used to store multiple variables in the memory in the continuous memory allocation on which starting index value is starting from 0 and the last index value location is size-1.

In java programming language the array.length is used to tells the size of the array so when the user wants to get the value of the last element, he needs to print the value of (array.length-1) location so the correct statement for the java programming language is to print the last element in the array named ar is--

System.out.println(ar[ar.length-1]);

No option provides the above statement, so option d (None of these) is correct while the reason behind the other option is not correct is as follows--

  • Option a will prints the size of the array.
  • Option b also gives the error because length is an undeclared variable.
  • Option c will give the error of array bound of an exception because it begs the value of the size+1 element of the array.

In a system where Round Robin is used for CPU scheduling, the following is TRUE when a process cannot finish its computation dur
masha68 [24]

Answer:

B. The process will be terminated by the operating system.

Explanation:

When Round Robin is used for CPU scheduling, a time scheduler which is a component of the operating system is used in regulating the operation. A time limit is set for each of the processes to be run.

So, when a process fails to complete running before its time elapses, the time scheduler would log it off and return it to the queue. This queue is in a circular form and gives each of the processes a chance to run its course.
