1 answer:

4 0

The variable declaration and initialization, that appears in a method in the same class as checkIndexes is checkIndexes(table, 4, 5).

<h3>What is declaration of a variable?</h3>

Declaration of a variable is known to be a function or work that is seen in computer programming language.

This is known to be a form of a statement that is known to be often used to state or specify the variable in regards to its name and that of its data type.

Note that the Declaration is known to be one that informs the compiler about the presence of an entity in that program and where one can find it.

Hence, The variable declaration and initialization, that appears in a method in the same class as checkIndexes is checkIndexes(table, 4, 5).

See full question below

Consider the following method.

public boolean checkIndexes(double[][] data, int row, int col)

{

int numRows = data.length;

if (row < numRows)

{

int numCols = data[0].length;

return col < numCols;

}

else

{

return false;

}

Consider the following variable declaration and initialization, which appears in a method in the same class as checkIndexes.

double[][] table = new double[5][6];

Which of the following method calls returns a value of true ?

A checkIndexes(table, 4, 5)

B checkIndexes(table, 4, 6)

C checkIndexes(table, 5, 4)

D checkIndexes(table, 5, 6)

E checkIndexes(table, 6, 5)

To pinpoint an earthquake's location, scientists need information from how many seismometers?

Mazyrski [523]

<span>C. 3
Due to the different speeds of P and S waves, a single seismometers can determine the distance to an earthquake. So, for a single station, the localization is any point on a circle around the station. With 2 stations, you'll have two circles that intersect at two points. The 3rd station is needed in order to determine which of the 2 points is the actual earthquake.</span>

Write an application that inputs a five digit integer (The number must be entered only as ONE input) and separates the number in

netineya [11]

Answer:

The program in Java is as follows:

import java.util.*;

public class Main{

public static void main(String[] args) {

int n, num;

Scanner input = new Scanner(System.in);

System.out.print("Number of inputs: ");

n = input.nextInt();

LinkedList<Integer> myList = new LinkedList<Integer>();

for(int i = 0; i<n;i++){

System.out.print("Input Integer: ");

num = input.nextInt();

while (num > 0) {

myList.push( num % 10 );

num/=10;

}

while (!myList.isEmpty()) {

System.out.print(myList.pop()+" ");

}

System.out.println();

myList.clear();

}

Explanation:

This declares the number of inputs (n) and each input (num) as integer

int n, num;

Scanner input = new Scanner(System.in);

Prompt for number of inputs

System.out.print("Number of inputs: "); n = input.nextInt();

The program uses linkedlist to store individual digits. This declares the linkedlist

LinkedList<Integer> myList = new LinkedList<Integer>();

This iterates through n

for(int i = 0; i<n;i++){

Prompt for input

System.out.print("Input Integer: ");

This gets input for each iteration

num = input.nextInt();

This while loop is repeated until the digits are completely split

while (num > 0) {

This adds each digit to the linked list

myList.push( num % 10 );

This gets the other digits

num/=10;

}

The inner while loop ends here

This iterates through the linked list

while (!myList.isEmpty()) {

This pops out every element of thelist

System.out.print(myList.pop()+" ");

}

Print a new line

System.out.println();

This clears the stack

myList.clear();

}
