"I can see that you've already rested. Great! Here are some tasks to practice creating constructors:"
You can't buy friends
A friend (Friend class) must have three constructors: - Name - Name, age - Name, age, sex.
The basis of a wheel
In the Circle class, create a constructor that initializes all the instance variables. The constructor must have three parameters.
Populate the Rectangle class
The parameters for the rectangle (Rectangle class) will be top, left, width, and height. Create as many constructors as possible. Examples: - 4 parameters are specified: left, top, width, height - width/height is not specified (both are 0); - height is not specified (it is equal to the width), we'll
Figure out what the program does. Find and fix one bug in the Circle class. Don't change the main method. Hint: Study the default constructor.
A cat (Cat class) must have five constructors: - Name - Name, weight, age - Name, age (standard weight) - Weight, color (name, address, and age are unknown; the cat is homeless); - Weight, color, address (someone else's pet). The constructor's job is to make the object valid. For example, if the wei
Calling a constructor from a constructor
Figure out what the program does. Correct the constructor with two parameters so that it calls another constructor with a radius of 10. Think about which constructor you need to call. Hint: carefully study the implementation of the default constructor.
Study the Circle class. Write the maximum number of possible constructors with different arguments. Hint: Don't forget about the default constructor.
