Question

Can someone help me with this?

Create a class called BMI with the following instance variables: name, age, weight (in pounds), and height. Create a constructor for your class so that you can create objects of type

BMI. Include all the methods such as accessors, mutators, toString, equals. Also include a method called getBMI which calculates the BMI for the person and returns the BMI. Use thefollowing formula. You need to convert the height to

inches and the weigh to kilogram. 1 kg =

.45 pounds

1 meter = .0254 inches

bmi = (weight in kg * heigh(in meter)) / (height in meter)* (height in meter)

Also include a method called getStatus to return a String representing the person’s status

bmi < 16 returns “seriously underweight

bmi < 18 returns

“underweight”

bmi < 24 “returns

normal weight”

bmi < 29 returns “overweight”

bmi < 35 returns “seriously overweight”

Anything else returns “gravely overweight”

Methods bmi and getStatus do not receive any parameters

Also include a driver class to create couple of the objects and output the bmi and the status for each person.

Explanation / Answer

Hello, I went through your question and have given the solution below. As you have asked for the driver class, a driver class is a simple class which has a main function where you can create an object of any class within the package. Now your second requirement to get the status and bmi of a person without an argument doesn't makes sense. You need to pass either the object of the BMI Class or the height and weight of the person as arguments. I have made a function taking height and weight as arguments and then calulating the BMI for it.

//Class BMI

public class BMI {

private String name;
private int age;
private int height;
private int weight;

// constructor for the Class BMI, Taking weight in pounds and height in inches

public BMI(String name,int age,int height,int weight){
   this.name=name;
   this.age=age;
   this.height=height;
   this.weight=weight;
  
}

// Method to calculate BMI Index

public float getBMI(int height, int weight){
   float weightInKg=(weight*100)/45;
   float heightInMeter=(height*254)/100;
   float bmiIndex=(weightInKg)/(heightInMeter*heightInMeter);
   return bmiIndex;
}

//Method to get status
public String getStatus(float bmiIndex){
   String status="";
  
   if(bmiIndex<16){
       status="seriously underweight";
       return status;
   }
   if(bmiIndex>=16 && bmiIndex<18 ){
       status="underweight";
       return status;
   }
   if(bmiIndex>=18 && bmiIndex<24){
       status="normal weight";
       return status;
   }
   if(bmiIndex>=24 && bmiIndex<29){
       status="overweight";
       return status;
   }
   if(bmiIndex>=29 && bmiIndex<35){
       status="seriously overweight";
       return status;
   }
  
   status="gravely overweight";
   return status;
}

// getters and setters

public String getName() {
   return name;
}

public void setName(String name) {
   this.name = name;
}

public int getAge() {
   return age;
}

public void setAge(int age) {
   this.age = age;
}

public int getHeight() {
   return height;
}

public void setHeight(int height) {
   this.height = height;
}

public int getWeight() {
   return weight;
}

public void setWeight(int weight) {
   this.weight = weight;
}

}

Thank you!!
