Evaluate the given pseudocode to calculate the body mass index (BMI) with the following test values:
A) The height = 1.80 meter and the weight = 78 Kg
B) The height = 1.50 meter and the weight = 85 Kg
Input height
Input weight
BMI = Weight / (height)2
If BMI < 18.5 then
Output BMI
Output “Underweight” Else
If BMI < 24.9 then
Output BMI
Output “Normal”
Else
If BMI > 25 then
Output BMI
Output “overweight”
End if
What is the final output of:
A)
B)
Write an algorithm to find the perimeter and the area of a rectangle.
. Find the errors in the following statements, explain why and how to solve such errors:
a. 23 = 25;
b. Int percentage% = “15”;
c. Rectangle void = new Rectangle (25, 30, 40, 50);
d. double 7average = 0;
7average.length();
We want to create a class that represents a clock. A clock has hour, minute, and second. For example, the time 12:15:36 means, it is 12 o’clock, 15 minutes, and 36 seconds. The basic framework of a Clock class is below: public class Clock
{ private int hour;
private int minutes;
private int seconds;
}
1. What should the body of the constructor be?
A. hr = hour;
min = minutes;
sec = seconds;
B. hour = 12;
minutes = 15;
seconds = 36;
C. int hour = hr;
int minutes = min;
int seconds = sec;
D. hour = hr;
minutes = min;
seconds = sec;
What are the implicit and the explicit parameters in the following methods call: A) System.out.println(“Assignment 1”);
B) myName.length()
