Question

Write the following problem in Java

• Create a class Dog, add name, breed, age, color as the attributes. You need to choose the right types for those attributes.
• Create a constructor that requires no arguments. In this constructor, initialize name, breed, age, and color as you wish.
• Define a getter and a setter for each attribute.
• Define a method toString to return a String type, the returned string should have this information:

“Hi, my name is Lucky. I am a Chiwawa. I am 3 years old, and my color is white.”

• Create a main method. In the main method, create a Dog type object and call setters to set its attributes. Print this object using System.out.println().
