create a new Java application called "CheckString" (without the quotation marks) according to the following guidelines.** Each m

jok3333 [9.3K]

Answer:

The Java code is given below

Explanation:

import java.io.*;

import java.util.Scanner;

import java.util.ArrayList;

public class StringCheck{

//There are several implementation approaches. This is one example framework/outline which might be helpful. Please feel free to try other approaches.

public static void checkWord(String word) throws Exception {

// Uses charAt method to test if the first letter of string variable word

// is a character. If not, throw new exception

if(Character.isLetter(word.charAt(0))){

return;

}else{

throw new Exception("This is not a word");

}

public static String getWord() {

// Declare a local scanner

// Prompt the user to enter a word

// Think about using a loop to give the user multiple opportunities to correctly enter a string

// Read into a string

// Call checkWord method passing the string as a parameter

// checkWord can throw an exception; call checkWord in a try/catch block

// Return the string to main if a valid string

Scanner sc = new Scanner(System.in);

boolean st = true;

String word = null;

while(st){

System.out.println("Enter a Word : ");

word = sc.next();

try{

checkWord(word);

st = false;

}catch(Exception e){

System.out.println(e);

st = true;

}

sc.close();

return word;

}

public static void writeFile(String[] arrayToWrite, String filename) throws IOException {

// Example using FileWriter but PrintWriter could be used instead

// Create a FileWriter object

FileWriter fileWordStream = new FileWriter(filename);

// Use a loop to write string elements in arrayToWrite to fileWordStream

for(int i = 0;i<arrayToWrite.length;i++){

fileWordStream.write(arrayToWrite[i]+System.lineSeparator());

}

fileWordStream.flush();

fileWordStream.close();

// In the loop use the lineSeparator method to put each string on its own line

}

public static ArrayList readFile(String filename) throws FileNotFoundException, IOException {

// Declare local ArrayList

ArrayList<String> words = new ArrayList<>();

// Create a new File object using filename parameter

File file = new File(filename);

// Check if the file exists, if not throw a new exception

if(!file.exists()){

throw new FileNotFoundException("File not Found");

}

// Create a new BufferedReader object

Scanner fsc = new Scanner(file);

// use a loop and the readLine method to read each string (on its own line) from the file

while(fsc.hasNextLine()){

words.add(fsc.nextLine());

}

fsc.close();

// return the filled ArrayList to main

return words;

}

public static void main(String[] args) {

// create a string with literal values to write to the file

String[] testData = {"cat", "dog", "rabbit"};

// Create an ArrayList for reading the file

ArrayList<String> words = new ArrayList<>();

// Declare a string variable containing the file name "data.txt"

String file = "data.txt";

// Call getWord, assign the returned string to a variable and display it

String word = getWord();

System.out.println("The word is : "+word);

// Call writeFile and readFile methods in a try block

try{

writeFile(testData,file);

words = readFile(file);

// Printout the contents of the ArrayList after the call to readFile

for(int i = 0;i<words.size();i++){

System.out.println(words.get(i));

}

}catch(FileNotFoundException e){

System.out.println(e);

}catch(IOException e){

System.out.println("IOException: error occured in input output");

}

// catch two types of exceptions

}

This morning when Paul turned on his computer at work, it would not boot. Instead, Paul reported that he heard a loud clicking n

IRISSAK [1]

Answer:

The problem with Paul's computer is that the magnetic hard drive failed.

Explanation:

A magnetic hard drive or hard disk is a non-volatile storage device, which is used to store different information on a computer.

The magnetic disk is made up of numerous magnetic plates, these plates are divided into sectors and tracks. A spindle is present in the middle to rotate the combined plates or the whole unit.

When there is a clicking noise coming from the magnetic disk, it could mean that one of the plates is damaged or if the power to the computer is inconsistent. This can greatly affect the performance of your computer.

It takes 2 seconds to read or write one block from/to disk and it also takes 1 second of CPU time to merge one block of records.

Alexxx [7]

Answer:

Part a: For optimal 4-way merging, initiate with one dummy run of size 0 and merge this with the 3 smallest runs. Than merge the result to the remaining 3 runs to get a merged run of length 6000 records.

Part b: The optimal 4-way merging takes about 249 seconds.

Explanation:

The complete question is missing while searching for the question online, a similar question is found which is solved as below:

Part a

For optimal 4-way merging, we need one dummy run with size 0.

Merge 4 runs with size 0, 500, 800, and 1000 to produce a run with a run length of 2300. The new run length is calculated as follows $L_{mrg}=L_0+L_1+L_2+L_3=0+500+800+1000=2300$
Merge the run as made in step 1 with the remaining 3 runs bearing length 1000, 1200, 1500. The merged run length is 6000 and is calculated as follows
