Consider the following static method, calculate.

public static int calculate(int x)
{
x = x + x;
x = x + x;
x = x + x;

return x;
}
Which of the following can be used to replace the body of calculate so that the modified version of calculate will return the same result as the original version for all values of x?

return 8 * x;
return 3 + x;
return 3 * x;
return 6 * x;
return 4 * x;

An administrative assistant is responsible for scheduling appointments at a doctor’s office. Which component would allow the administrative assistant to enter each patient’s name, date of birth, doctor’s name, and appointment date and time?

A restaurant recorded the ages of customers on two separate days. You are going to write a program to compare the number of customers in their twenties (ages 20 to 29). What is the missing line of code to count the number of customers in their twenties? customerAges = [13, 3, 11, 24, 35, 25, 15, 18, 1] count20s = 0 if 20 <= item <= 29: count20s = count20s + 1

Consider the following class declarations.

public class Dog
{
private String name;
public Dog()
{
name = "NoName";
}
}
public class Poodle extends Dog
{
private String size;
public Poodle(String s)
{

size = s;
}
}

The following statement appears in a method in another class.
Poodle myDog = new Poodle("toy");
Which of the following best describes the result of executing the statement?

a. The Poodle variable myDog is instantiated as a Poodle. The instance variable size is initialized to "toy". The instance variable name is not assiged a value.
b. The Poodle variable myDog is instantiated as a Poodle. The instance variable size is initialized to "toy". An implicit call to the no-argument Dog constructor is made, initializing the instance variable name to "NoName".
c. The Poodle variable myDog is instantiated as a Poodle. The instance variable size is initialized to "toy". An implicit call to the no-argument Dog constructor is made, initializing the instance variable name to "toy".
d. A runtime error occurs because super is not used to call the no-argument Dog constructor.
e. A runtime error occurs because there is no one-argument Dog constructor.

SummaryIn this lab, you complete a partially prewritten Java program that uses an array.The program prompts the user to interactively enter eight batting averages, which the program stores in an array. The program should then find the minimum and maximum batting average stored in the array as well as the average of the eight batting averages. The data file provided for this lab includes the input statement and some variable declarations. Comments are included in the file to help you write the remainder of the program.Instructions1.Ensure the file named BattingAverage.java is open.Write the Java statements as indicated by the comments.Execute the program by clicking "Run Code." Enter the following batting averages: .299, .157, .242, .203, .198, .333, .270, .190. The minimum batting average should be .157, and the maximum batting average should be .333. The average should be .2365.import java.util.Scanner;public class BattingAverage{public static void main(String args[]){Scanner s = new Scanner(System.in);// Declare a named constant for array size here.// Declare array here.// Use this integer variable as your loop index.int loopIndex;// Use this variable to store the batting average input by user.double battingAverage;// String version of batting average input by user.String averageString;// Use these variables to store the minimim and maximum batting averages.double min, max;// Use these variables to store the total and the average.double total, average;// Write a loop to get batting averages from user and assign to array.System.out.println("Enter a batting average: ");averageString = s.nextLine();battingAverage = Double.parseDouble(averageString);// Assign value to array.// Assign the first element in the array to be the minimum and the maximum.min = averages[0];max = averages[0];// Start out your total with the value of the first element in the array.total = averages[0];// Write a loop here to access array values starting with averages[1]// Within the loop test for minimum and maximum batting averages.// Also accumulate a total of all batting averages.// Calculate the average of the 8 averages.// Print the averages stored in the averages array.// Print the maximum batting average, minimum batting average, and average batting average.System.exit(0);}{
