Answer 1

public class Question_16 {

    private String name;
    private int age;
    private double height;

    public Question_16() {
        name = "";
        age = 0;
        height = 0;
    }

    public Question_16(String name, int age, double height) {
        this.name = name;
        this.age = age;
        this.height = height;
    }

    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 double getHeight() {
        return height;
    }

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

    @Override
    public String toString() {
        return "Name: " + name + ", " + "Age: " + age + ", Height: " + height;
    }

    public void print() {
        System.out.println(toString());
    }

    public static void main(String[] args) {
        Question_16 question_16 = new Question_16("Ronaldo", 32, 186);
        question_16.print();
    }
