Implement a simulator for a process scheduling system using a heap. Jobs will be read from a file in this system that contains the job id, a six-character string, the length in seconds, and the priority of the job, an integer whose greater value indicates a higher priority. Each work will also receive an arrival number, which is an integer that indicates the order in which it arrived. The output of the simulation should include the job id, priority, duration, and completion time (relative to the simulation's start time of 0).

When an author produces an index for his or her book, the first step in this process is to decide which words should go into the index; the second is to produce a list of the pages where each word occurs. Instead of trying to choose words out of our heads, we decided to let the computer produce a list of all the unique words used in the manuscript and their frequency of occurrence. We could then go over the list and choose which words to put into the index. The main object in this problem is a "word" with associated frequency. The tentative definition of "word" here is a string of alphanumeric characters between markers where markers are white space and all punctuation marks; anything non-alphanumeric stops the reading. If we skip all un-allowed characters before getting the string, we should have exactly what we want. Ignoring words of fewer than three letters will remove from consideration such as "a", "is", "to", "do", and "by" that do not belong in an index. In this project, you…

Write a program that performs a survey on beverages. The program should prompt for the next person until a lookout value of -1 is entered to terminate the program. Each person participating in the survey should choose their favorite beverage from the following list? 1. Coffee 2. Tea 3. Coke 4. Orange Juice.

JAVA Task, by using ArrayList   The program reads manatee names from the standard input stream and from time to time prints a sorted portion of the list of names. All the manatee names in the input are given in the order in which the necropsy was performed. You can imagine a unique timestamp associated with each necropsy. The names are not necessarily unique (many of the manatees have the same name). Interspered in the standard input stream are queries that begin with the question mark character. Queries ask for an alphabetical list of manatee names to be printed to the standard output stream. The list depends only on the names upto that point in the input stream and does include any manatee names that appear in the input stream after the query. The list does not contain all the names of the previous necropsies, but only a selection of them. A query provides the names of two manatees, say A and B. The response to the query drops necropsies performed before the first named A and all the…
