Question

Create two java programs. The first will ask the user to enter three integers.

Once the three integers are entered, ask the user to enter one of three functions. The “average” if they want the average of the three numbers entered, enter “min” if they want the minimum and “max” if they want the maximum.

Display the answer.

Ask the user if they want to calculate another function for the three numbers. If so, loop and ask what function they want, otherwise terminate the program.

The calculation of the answer must be done by a method that is in the second program.

The second java program will have a constructor, three instance variables of type integer and three methods. The constructor will require three integers that will place them in their corresponding instance variables.

The methods will be called average, minimum and maximum. They will all require no arguments and will return an int.

The average method will use the three instance variables as input and calculate the average of all three and return the average as an integer.

The maximum method will use the three instance variables as input and calculate the maximum of all three and return the maximum as an integer.

The minimum method will use the three instance variables as input and calculate the minimum of all three and return the minimum as an integer.

*******PROGRAM 1********

import java.util.Scanner;

public static void main(String[] args) {
Scanner sc = new Scanner(System.in);

//Take three numbers as input
System.out.println("Enter the First Number");
int num1 = sc.nextInt();
System.out.println("Enter the Second Number");
int num2 = sc.nextInt();
System.out.println("Enter the Third Number");
int num3 = sc.nextInt();
Program_2 calculate = new Program_2(num1, num2, num3);
int z ;
do {
//Asking the user to enter one of three functions.
System.out.println("Enter one of the three functionality");
String function = sc.next();
switch (function) {
case "average":
int avg=calculate.average();

break;
case "min":
int min=calculate.mininum();

break;
case "max":
int max=calculate.maximum();

}
System.out.println("Do you want to continue ?");
String check = sc.next();
if (check.equals("yes")) {
z = 1;
} else {
z = 0;
}
} while (z != 0);

}

}

*******PROGRAM 2********

class Program_2 {

int num_1;
int num_2;
int num_3;

Program_2(int num1, int num2, int num3) {
this.num_1 = num1;
this.num_2 = num2;
this.num_3 = num3;
}
//function to find average

int average() {
int result = (num_1 + num_2 + num_3) / 3;
return result;
}

//function to find maximum
int maximum() {
int result = num_1;
if (num_2 > result) {
result = num_2;
}
if (num_3 > result) {
result = num_3;
}
return result;
}

//function to find minimum
int mininum() {
int result = num_1;
if (num_2 < result) {
result = num_2;
}
if (num_3 < result) {
result = num_3;
}
return result;
}
}

*****OUTPUT FOR THE GIVEN CODE*****

run: Enter the First Number 4. Enter the Second Number Enter the Third Number Enter one of the three functionality average Average of the three number is : 6 Do you want to continue ? yes Enter one of the three functionality min Minimum of the three number is :4 Do you want to continue ? yes Enter one of the three functionality max Maximum of the three number Do you want to continue ? no BUILD SUCCESSFUL (total time: 36 seconds)
