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()
