In JAVA please:

blagie [28]

Answer:

import java.util.Scanner;

public class ArraysKeyValue {

public static void main (String [] args) {

final int SIZE_LIST = 4;

int[] keysList = new int[SIZE_LIST];

int[] itemsList = new int[SIZE_LIST];

int i;

keysList[0] = 13;

keysList[1] = 47;

keysList[2] = 71;

keysList[3] = 59;

itemsList[0] = 12;

itemsList[1] = 36;

itemsList[2] = 72;

itemsList[3] = 54;

/* Your solution goes here */

for ( i = 0; i < SIZE_LIST; i++){

if (keysList[i]>50){

System.out.println(itemsList[i] + " "); } }

System.out.println("");

}

Explanation:

I will explain the whole program flow.

There are two arrays here

keysList and itemsList

The first list (keysList) contains the following elements:

13 element at first position of the array (0th index)

47 element at second position of the array (1st index)

71 element at third position of the array (2nd index)

59 element at fourth position of the array (3rd index)

The other list (itemsList) contains the following elements:

12 element at first position of the array (0th index)

36 element at second position of the array (1st index)

72 element at third position of the array (2nd index)

54 element at fourth position of the array (3rd index)

The size of the array elements is fixed which is 4 and is stored in the variable SIZE_LIST.

Then the loop starts. The loop contains a variable i which is initialized to 0. First it checks if the value of i is less than the size of the list. It is true as SIZE_LIST=4 and i=0.
So the program control enters the body of the loop.
In first iteration, IF condition checks if the i-th element of the keysList is greater than 50. As i=0 So the element at 0th index of the keysList is 13 which is not greater than 50 so the body of IF statement will not execute as the condition evaluates to false. The value of i increments by 1 so now i becomes 1.
In next iteration loop again checks if the value of i is less than the size of the list which is true again so the body of the loop executes.

IF condition checks if the i-th element of the keysList is greater than 50. As i=1 So the element at 1st index of the keysList is 47 which is not greater than 50 so the body of IF statement will not execute as the condition evaluates to false. The value of i is incremented by 1 so now i becomes 2.

In next iteration loop again checks if the value of i is less than the size of the list which is true again as i= 2 which is less than SIZE_LIST so the body of the loop executes.

IF condition checks if the i-th element of the keysList is greater than 50. As i=2 So the element at 2nd index of the keysList is 71 which is greater than 50 so the body of IF statement is executed as the condition evaluates to true. So in the body of the IF statement there is a print statement which prints the i-th element of the itemsList. As i = 2 so the value at the index 2 of the itemsList is displayed in the output which is 72. Next value of i is incremented by 1 so now i becomes 3.

In next iteration loop again checks if the value of i is less than the size of the list which is true again as i= 3 which is less than SIZE_LIST so the body of the loop executes.

IF condition checks if the i-th element of the keysList is greater than 50. As i=3 So the element at 3rd index of the keysList is 59 which is greater than 50 so the body of IF statement is executed as the condition evaluates to true. So in the body of the IF statement there is a print statement which prints the i-th element of the itemsList. As i = 3 so the value at the index 3 of the itemsList is displayed in the output which is 54. Next value of i is incremented by 1 so now i becomes 4.

In next iteration loop again checks if the value of i is less than the size of the list which is now false as i=4 which is equal to the SIZE_LIST= 4. So the loop breaks.
So the output of the above program is:

72

54

List five ways in which the type declaration system of a language such as Java or C differs from the data definition language us

zhannawk [14.2K]

Answer:

Hi Sevanah! Below are the five main differences between a type declarative language and a data definition language:

A data definition language:

1. define data structure

2. define the column attributes of a table

3. no further classifications

4. The basic commands in a Data Definition language are CREATE, DROP, RENAME, ALTER

5. Scope of variables in data definition languages is limited

A type declarative language:

1. manipulate the data itself

2. uses functions to add and update the rows of a table

3. further classified into procedural and non-procedural languages

4. The basic commands are INSERT, UPDATE and MERGE

5. Scope of variables in type declarative languages is varied

Explanation:

A data definition language is used to define data structures. It makes use of statements such as create table, alter table to create and alter the database schema to allow it to hold rows of information. A type declarative language such as Java or C is used to manipulate the data itself. For example, insert, update and deletion of rows to the database. Whereas data definition languages define the column attributes of a table, a type declaration language uses functions to add and update the rows of a table. A data definition language does not have any further classification, however a type declarative language can be further classified into procedural and non-procedural languages. The basic commands in a Data Definition language are CREATE, DROP, RENAME, ALTER, whereas the basic commands in a type declarative language are INSERT, UPDATE and MERGE. There is little of no scope of variables in a data definition language, whereas the scope of variables in type declarative languages is varied

Black box testing is the practice of writing tests without knowing the implementation of the code you're testing. White box test

Lelu [443]

Answer:

First test: Give a list of disordered numbers to the sorting algorithm an examine if the output is correctly sorted.

Second test: Give a list of ordered numbers to the sorting algorithm an analyze if the output is still correctly ordered.

Third test: Give a list of ordered numbers and some non-numeric values to the sorting algorithm and check how is managed the exception in case of error or if the output is correctly ordered.
