Question

Java’s class Color has a constructor that takes three integers as parameters: the red, green, and blue components of the color. A class Balloon has two fields: double radius and Color color. Write a constructor for the Balloon class that takes no parameters and sets the balloon’s radius to 10 and its color to "sky blue" (with RGB values 135, 206, and 250).

Answer 1

public Balloon(){

//Invokes the 2 argument constructor for balloon with relevant

//parameters

this(10,new Color(135,206,250));

}

Step-by-step explanation:

class Balloon{

//Private fields in the Balloon class

private double radius = 0;

private Color c = null;

// Constructor with two arguments - radius and Color

public Balloon(double radius,Color c){

this.radius = radius;

this.c = c;

}

// No argument constructor

public Balloon(){

//Invokes the 2 argument constructor for balloon with relevant

//parameters

this(10,new Color(135,206,250));

}

}
