Consider the following short paragraph: On a computer with a single core CPU, attempting to program real concurrency between two

processes (as opposed to apparent concurrency) is impossible, because the CPU can in actuality only do one thing at a time. To fake the user into thinking that more than one process is running at the same time, the CPU can, for example, switch back and forth between running each process very quickly. Choose one of the following statements about this paragraph: Group of answer choices It is all true It is all false Some of it is true, and some of it is false

Write the definition of the function inputArray that prompts the user to input 20 numbers and stores the numbers into alpha. Wri
Alina [70]

Answer:

In Java:

public static  int[] inputArray(){

   Scanner input = new Scanner(System.in);

   int[] alpha = new int[20];

   for(int i = 0;i<20;i++){

       alpha[i] = input.nextInt();

   }

   return alpha;}

public static  int[] doubleArray(int [] alpha){

   int[] beta = new int[20];

   for(int i = 0;i<20;i++){

       beta[i] = 2 * alpha[i];

   }

   return beta;

}

public static int[] copyAlphaBeta(int [] alpha, int [] beta){

   int [] AlphaBeta = new  int[10];

   for(int i = 0;i<5;i++){

       AlphaBeta[i] = alpha[i];

   }

   int count = 5;

   for(int i = 15;i<20;i++){

       AlphaBeta[count] = beta[i];

       count++;

   }

   return AlphaBeta;

}

public static void printArray(int [] alpha){

   for(int i = 0;i<20;i++){

       System.out.print(alpha[i]+" ");

       if((i+1)%15 == 0){

           System.out.println(" ");

       }

   }

}

Explanation:

The inputArray is defined here

public static  int[] inputArray(){

   Scanner input = new Scanner(System.in);

This declares alpha array of 20 elements

   int[] alpha = new int[20];

The following iteration gets input from the user into the array

<em>    for(int i = 0;i<20;i++){</em>

<em>        alpha[i] = input.nextInt();</em>

<em>    }</em>

This returns the alpha array

   return alpha;}

The doubleArray is defined here. It takes the alpha array as its input parameter

public static  int[] doubleArray(int [] alpha){

This declares beta of 20 integers

   int[] beta = new int[20];

This populates beta by 2 * alpha[i]

<em>    for(int i = 0;i<20;i++){</em>

<em>        beta[i] = 2 * alpha[i];</em>

<em>    }</em>

This returns the alpha array

   return beta;}

The copyAlphaBeta array is defines here

public static int[] copyAlphaBeta(int [] alpha, int [] beta){

This declares AlphaBeta as 10 elements

   int [] AlphaBeta = new  int[10];

This populates the first 5 elements of AlphaBeta with the first 5 of alpha

<em>    for(int i = 0;i<5;i++){</em>

<em>        AlphaBeta[i] = alpha[i];</em>

<em>    }</em>

   int count = 5;

This populates the last 5 elements of AlphaBeta with the last 5 of beta

<em>    for(int i = 15;i<20;i++){</em>

<em>        AlphaBeta[count] = beta[i];</em>

<em>        count++;</em>

<em>    }</em>

This returns the AlphaBeta array

   return AlphaBeta;

}

The printArray is defined here. It takes the alpha array as its input parameter

public static void printArray(int [] alpha){

This iterates through alpha array

   for(int i = 0;i<20;i++){

This prints each element of the array

       System.out.print(alpha[i]+" ");

A new line is started after the 15th element

<em>        if((i+1)%15 == 0){</em>

<em>            System.out.println(" ");</em>

<em>        }</em>

   }

}

Write the declaration statement for a two-dimensional array X of integers with five rows and five columns that accepts 25 intege
madreJ [45]

Answer:

int[ ][ ] X = new int[5][5];

It can also be declared and initialized this way:

  int[][] X = {

               {1,2,3,6,8},

               {4, 5, 6, 9},

               {7,5,6,8,9},

               {8,5,8,8,9},

               {10,2,6,8,11},

       };

Explanation:

Above is a declaration of a two-dimensional array that can hold 5*5=25 int values. A java program is given below:

public class JavaTwoD{

   public static void main(String args[ ]) {

       // creating the 5X5 array

       int[ ][ ] X = new int[5][5];

       // looping through the array to add elements

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

           for (int j = 0; j < X[i].length; j++) {

               X[i][j] = i * j;

           }

       }
