- JAVA - Okay I have been attempting this for the past hour and I am really stuck and keep getting an error... The error says that I keep missing a main thread but its there... help!
Given a main program that searches for the ID or the name of a student from a text file, complete the findID() and the findName() methods that return the corresponding information of a student. Then, insert a try/catch statement in main() to catch any exceptions thrown by findID() or findName(), and output the exception message. Each line in the text file contains the name and the ID of a student, separated by a space.
Method findID() takes two parameters, a student's name and a Scanner object containing the text file's contents. Method findID() returns the ID associated with the student's name if the name is in the file, otherwise the method throws an Exception object with the message "Student ID not found for studentName", where studentName is the name of the student.
Method findName() takes two parameters, a student's ID and a Scanner object containing the text file's contents. Method findName() returns the name associated with the student's ID if the ID is in the file, otherwise the method throws an Exception object with the message "Student name not found for studentID", where studentID is the ID of the student.
The main program takes three inputs from a user: the name of a text file (String), a user choice of finding the ID or the name of a student (int), and the ID or the name of a student (String). If the user choice is 0, findID() is invoked with the student's name as one of the arguments. If the user choice is 1, findName() is invoked with the student's ID as one of the arguments. The main program finally outputs the result of the search or a message if an exception is caught.
Ex: If the input of the program is:
roster.txt 0 Reagan
and the contents of roster.txt are:
Reagan rebradshaw835
Ryley rbarber894
Peyton pstott885
Tyrese tmayo945
Caius ccharlton329
the output of the program is:
rebradshaw835
Ex: If the input of the program is:
roster.txt 0 Mcauley
the program outputs an exception message:
Student ID not found for Mcauley
Ex: If the input of the program is:
roster.txt 1 rebradshaw835
the output of the program is:
Reagan
Ex: If the input of the program is:
roster.txt 1 mpreston272
the program outputs an exception message:

Explanation:
- You should call your file the same as your class (i.e., LabProgram.java)
- I added a try/catch to both find calls, to catch the exception
- The find methods are very similar, they loop through the lines of the roster, splitting each line at a space and doing string comparison.

4. Suppose you replace the hard disk in the previous question with an optical drive like a DVD drive. The drive you use has an average access time of 185ms and can-do sustained reads at 1600 Kbytes per second. How long will it take, including access time, to read the same 750 Kbytes off this optical disk (again, assuming all the data is in sequential sectors on same track)
The total time it will take to read the same 750 Kbytes off the optical disk is 653.75 ms
Considering the parameters given in the question, the total time taken to read the same drive is the addition of the average access time together with the time to transfer the data.
Mathematically;
Total Time taken = Access time (avg.) + data transfer time
where;
access time(avg.) = 185 msthe data transfer time can be estimated by using the formula:
= required quantity of data transferred/ speed of data transfer
= 750 kbytes ÷ 1600 Kbytes/s
= 0.46875 s
= 468.75 ms
∴
Total Time taken = 185 ms + 468.75 ms
= 653.75 ms

Next, you will implement the reserveAnimal() method. Your completed method should do the following: Prompt the user for input. The user should enter their desired animal type and country. o If there is an available animal which meets the user's input criteria, the method should access an animal object from an ArrayList. If there are multiple animals that meet these criteria, the program should access the first animal in the ArrayList. The method should also update the "reserved" attribute of the accessed animal. o If there is not an available animal which meets the user's input criteria, the method should output feedback to the user letting them know that no animals of that type and location are available. 6. Finally, you have been asked to implement a printAnimals() method that provides easy-to-read output displaying the details of objects in an ArrayList. o To demonstrate this criterion in a "proficient" way, your implemented method must successfully print the ArrayList of dogs or the ArrayList of monkeys. o To demonstrate this criterion in an "exemplary" way, your implemented method must successfully print a list of all animals that are "in service" and "available". import java.util.ArrayList; import java.util.Scanner; public class Monkey extends RescueAnimal{ private String species, tailLength, height, bodyLength; public Monkey (String name, String species, String tailLength, String height, String bodyLength, String gender, String age, String weight, String acquisitionDate, String acquisitionCountry, String trainingStatus, boolean reserved, String in ServiceCountry) { setName(name); setSpecies (species); setTailLength(tailLength); setHeight(height); setBodyLength(bodyLength); setGender(gender); setAge(age); setWeight(weight); setAcquisitionDate(acquisitionDate); setAcquisition Location(acquisitionCountry); setTrainingStatus (trainingStatus); setReserved(reserved); setInServiceCountry(inServiceCountry); } //Accessor and Mutator methods public String getSpecies() { return species; } public void setSpecies (String monkey Species) { species = monkeySpecies; } public String getTailLength() { return tailLength; } public void setTailLength(String monkeyTailLength) { tailLength = monkeyTailLength; } public String getHeight() { return height; } public void setHeight(String monkeyHeight) { height = monkeyHeight; } public String getBodyLength() { return bodyLength; } public void setBodyLength(String monkeyBodyLength) { bodyLength = monkeyBodyLength; } } public class Dog extends RescueAnimal { // Instance variable private String breed; // Constructor public Dog(String name, String breed, String gender, String age, String weight, String acquisitionDate, String acquisitionCountry, String trainingstatus, boolean reserved, String inServiceCountry) { setName(name); setBreed (breed); setGender(gender); setAge(age); setWeight(weight); setAcquisitionDate(acquisitionDate); setAcquisitionLocation(acquisitionCountry); setTrainingstatus (trainingstatus); setReserved (reserved); setInServiceCountry(inServiceCountry); } // Accessor Method public String getBreed() { return breed; } // Mutator Method public void setBreed(String dogBreed) { breed = dogBreed; } }
Answer:
To demonstrate this criterion in a "proficient" way, your implemented method must successfully print the ArrayList of dogs or the ArrayList of monkeys
In the provided code, the reserveAnimal() method prompts the user to enter an animal type and country. It then searches for an available animal in an ArrayList based on the user's input.

9.1 a. What is a device register? b. What is a device data register? c. What is a device status register?
(a) A device register is a register (or memory location) that is used for data transfer
to/from an input/output device. It provides a means of communication between the
processor and the input/output device. The processor can poll this register to find out
whether it has received an input or it can send an output from/to the specific device that the device register belongs to. In memory mapped I/O device registers are dedicated memory locations for each I/O device. There may be more than one device register (dedicated memory location) for one device.
(b) A device data register is a device register (a dedicated memory location in
memorymapped I/O) that holds the data that is to be input/output.
(c) A device status register is a device register (a dedicated memory location in
memorymapped I/O) that indicates the status of the input/output. It allows for the
processor to know whether or not input/output of the value in the device data register has occurred. Basically it is an important step to achieve synchronization in an asynchronous I/O system.
A ) Registered Devices means the MAC Address of a network interface on a Compatible Device in the name of the Customer registered (in a manner as ASK4 shall from time to time determine) to receive the Service and/or an Additional Service.
b) A device data register is a device register (a dedicated memory location in memorymapped I/O) that holds the data that is to be input/output. (c) A device status register is a device register (a dedicated memory location in memorymapped I/O) that indicates the status of the input/output.
(c) A device status register is a device register (a dedicated memory location in memorymapped I/O) that indicates the status of the input/output. It allows for the processor to know whether or not input/output of the value in the device data register has occurred.
What is the purpose of using status register?The status register lets an instruction take action contingent on the outcome of a previous instruction. Typically, flags in the status register are modified as effects of arithmetic and bit manipulation operations. For example, a Z bit may be set if the result of the operation is zero and cleared if it is nonzero.
