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()
