For this exercise, we are going to take a look at an alternate Calculator class, but this one is broken. There are several scope

vekshin1

Answer:

public class Calculator {

private int total;

private int value;

public Calculator(int startingValue){

// no need to create a new total variable here, we need to set to the our instance total variable

total = startingValue;

value = 0;

}

public int add(int value){

//same here, no need to create a new total variable. We need to add the value to the instance total variable

total = total + value;

return total;

}

/**

* Adds the instance variable value to the total

*/

public int add(){

// no need to create a new total variable. We need to add the value to the instance total variable

total += value;

return total;

}

public int multiple(int value){

// no need to create a new total variable. We need to multiply the instance total variable by value.

total *= value;

return total;

}

//We need to specify which value refers to which variable. Otherwise, there will be confusion. Since you declare the parameter as value, you need to put this keyword before the instance variable so that it will be distinguishable by the compiler.

public void setValue(int value){

this.value = value;

}

public int getValue(){

return value;

}

Tp-24 What should you do before starting an inboard gasoline engine

Minchanka [31]

Before starting an inboard gasoline engine, you should remove the engine cover completely to let the engine air out. Next is to change the fuel filter or the water separator. Marine fuel filters and water separators help draw water from the boat fuel, therefore protecting the motor from the water. If water were to get in, it could cause serious problems.

You should also consider changing the engine oil. This is especially so if the motor boat has been sitting around for a while. The fourth step is to change the oil filter. It is recommended that the oil filter is changed every 100 hours or every season. Other steps include;

Recharge the battery.

Refuel your boat.

Check the cooling system.

Create an enumeration named Month that holds values for the months of the year. With JANUARY equal to 1, FEBRUARY equal to 2, an

maria [59]

Answer:

import java.util.Scanner;

public class Question {

public enum Months{

JANUARY, FEBRUARY, MARCH, APRIL, MAY, JUNE, JULY, AUGUST, SEPTEMBER, OCTOBER, NOVEMBER, DECEMBER

}

public static void main(String args[]) {

Scanner scan = new Scanner(System.in);

System.out.println("Enter a month number>>: ");

int inputNumber = scan.nextInt();

if(inputNumber > 12 || inputNumber < 1){

System.out.println("Please enter a valid number.");

} else {

System.out.println(Months.values()[inputNumber - 1]);

}

Explanation:

The import statement at the top of the class is to help us receive user input via the keyboard. The class was defined named "Question". Then the enum was declared listing all the months. Then the main function was declared. The Scanner object was created as scan, then the user is prompted for input which is assigned to inputNumber. The user input is validated to be within the range of 1 - 12; if it is outside the range, the user shown an error message. If the input is correct, the appropriate month is displayed to the user. To get the appropriate month, we subtract one from the user input because the enum class uses the zero-index counting; it start counting from zero.
