Question

(Java) Create a program using 3 methods. The methods must be public and static. Ask the user for 3 numbers, then call the methods from main to print max, min, and average.

The first method max (int x, int y, int z) returns the maximum value of 3 integer values.

The second method min (int X, int y, int z) returns the minimum value of 3 integer values.

And the third average (int x, int y, int z) returns the average of 3 integer values.

Sample Output: (bold = user input)

Enter # 1: 5

Enter # 2: 9

Enter # 3: 2

Min is 2

Max is 9

Average is 5.33333

Sample output 2

Enter # 1: 45

Enter # 2: 11

Enter # 3: -3

Min is -3

Max is 45

Average is 17.6667

Code Example:

int addTwoNumbers (int x, int y) {

int result = x + y;

return result;

Answer 1

Code:

import java.util.*;

class Test60 {
public static void main(String args[]) {
Scanner sc = new Scanner(System.in);

int a, b, c;
int minimum, maximum;
float avg;

// Inputting the value of the 1st integer

System.out.print("Enter # 1: ");
a = sc.nextInt();

// Inputting the value of the 2nd integer

System.out.print("Enter # 2: ");
b = sc.nextInt();

// Inputting the value of the 3rd integer

System.out.print("Enter # 3: ");
c = sc.nextInt();
  
minimum = Test60.min(a, b, c); // Calling the method- min()
  
maximum = Test60.max(a, b, c); // Calling the method- max()
  
avg = Test60.average(a, b, c); // Calling the method- average()

// Displaying the maximum, minimum and the average of the 3 integers

System.out.println("Min is " + minimum);
System.out.println("Max is " + maximum);
System.out.printf("Average is %.5f", avg);
}

// Method- max() -> Returns the maximum of the 3 integers

public static int max(int x, int y, int z) {
if(x >= y && x >= z)
return x; // x is the largest
else if(y >= x && y >= z)
return y; // y is the largest
else
return z; // z is the largest
}

// Method- min() -> Returns the minimum of the 3 integers

public static int min(int x, int y, int z) {
if(x <= y && x <= z)
return x; // x is the smallest
else if(y <= x && y <= z)
return y; // y is the smallest
else
return z; // z is the smallest
}

// Method- average() -> Returns the average of the 3 integers

public static float average(int x, int y, int z) {
float avg = (x + y + z) / 3.0f;
  
return avg;
}
}
