Which is the best description of the difference between bound and unbound forms? O Bound forms are similar to hierarchical forms

but pop up in a separate window, while unbound forms are flat forms that do not have subforms. O Bound forms are linked to a table or query, while unbound forms are not linked to a table or query but are used to operate and navigate a database. O Bound forms perform tasks based on user input, while unbound forms navigate between multiple forms. O Bound forms are the basic interface for inputting information into tables or queries, while unbound forms ha more subforms within the main form. one or​

Answer and Explanation:

Abstract class Point {

   int x = 1, y = 1;

   void move(int dx, int dy) {

       x += dx;

       y += dy;

       alert();

   }

   abstract void alert();

}

abstract class Colored Point extends Point {

   int color;

}

class Simple Point extends Point {

   void alert() { }

}

Here, a class Point is proclaimed that must be declared abstract, in light of the fact that it contains an assertion of a unique strategy named alert. The subclass of Point named Colored Point acquires the dynamic technique alert, so it should likewise be proclaimed theoretical. Then again, the subclass of Point named Simple Point gives a usage of alarm, so it need not be dynamic.

The statement:

Point p = new Point();

would bring about an aggregate time mistake; the class Point can't be launched in light of the fact that it is theoretical. Be that as it may, a Point variable could accurately be instated with a reference to any subclass of Point, and the class Simple Point isn't digest, so the statement:

Point p = new Simple Point();

would be correct. Instantiation of a Simple Point causes the default constructor and field initializers for x and y of Point to be executed.

1 convert (101011)2 ( )10 ? convert(596)10= ( )16 ? convert( 101011101)2 ( )16 ? convert(37)10= ( )2 ?​
Sedaia [141]
<h2>Question:</h2>

(a) convert (101011)₂ = ( )₁₀ ?

(b) convert(596)₁₀= ( )₁₆ ?

(c) convert( 101011101)₂ = ( )₁₆ ?

(d) convert(37)₁₀= ( )₂ ?​

<h2>Answer:</h2>

(a) (101011)₂ = ( 43)₁₀

(b) (596)₁₀= ( 254)₁₆

(c) ( 101011101)₂ = ( 15D)₁₆

(d) (37)₁₀= ( 100101)₂

<h2>Explanation:</h2>

(a) convert (101011)₂ = ( )₁₀

This means that (101011)₂ be converted to base 10 (decimal).

<em>To convert from binary to decimal, find the sum of the binary digits times their power of 2. i.e</em>

(101011)₂ = 1 x 2⁵ + 0 x 2⁴ + 1 x 2³ + 0 x 2² + 1 x 2¹ + 1 x 2⁰

(101011)₂ = 1 x 32 + 0 x 16 + 1 x 8 + 0 x 4 + 1 x 2 + 1 x 1

(101011)₂ = 32 + 0 + 8 + 0 + 2 + 1

(101011)₂ = 43₁₀

Therefore, (101011)₂ = ( 43)₁₀

(b) convert(596)₁₀= ( )₁₆

This means that (596)₁₀ be converted to base 16 (hexadecimal).

<em>To convert from decimal to hexadecimal, </em>

i. start by dividing the decimal number by 16 taking note of the result and the remainder.

ii. divide the result obtained in (i) by 16 and take note of the new result and the remainder.

iii. repeat steps i and ii until the result is 0.

iv. the result is a combination of the remainders starting from the last.

<u>16 | 596</u>

<u>16 | 37</u> r 4

<u>16 | 2</u> r 5

<u>     | 0</u> r 2

Now combine the remainders starting from the bottom up. i.e

254₁₆

Therefore, (596)₁₀= ( 254)₁₆

(c) convert ( 101011101)₂ = ( )₁₆

This means that (101011101)₂ be converted to base 16 (hexadecimal).

<em>To convert from binary to hexadecimal, </em>

i. starting from the rightmost bit, group the binary digits into a group of 4 bits as follows

101011101 => 1   0101    1101

ii. the group that does not contain 4 bits is padded with 0s

101011101 => 0001   0101    1101

iii. using the hexadecimal table, convert each group to hexadecimal as follows.

0001 = 1

0101 = 5

1101 = D

iv. combine the result

15D

Therefore, ( 101011101)₂ = ( 15D)₁₆

(d)  convert(37)₁₀= ( )₂

This means that (37)₁₀ be converted to base 2 (binary).

<em>To convert from decimal to binary, </em>

i. start by dividing the decimal number by 2 taking note of the result and the remainder.

ii. divide the result obtained in (i) by 2 and take note of the new result and the remainder.

iii. repeat steps i and ii until the result is 0.

iv. the result is a combination of the remainders starting from the last.

<u>2 | 37</u>

<u>2 | 18</u> r 1

<u>2 | 9</u> r 0

<u>2 | 4</u> r 1

<u>2 | 2</u> r 0

<u>2 | 1</u> r 0

<u>   | 0</u> r 1

Now combine the remainders starting from the bottom up. i.e

100101₂

Therefore, (37)₁₀= ( 100101)₂

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

}

}
