The title
Design an Equipment class Equipment. This class has two properties, one is name, the type is string, the other is price, the type is int. Then instantiate three specific pieces of equipment and print their names and prices.
Analysis of the
It looks at the creation of classes and how to instantiate an object, along with overriding the toString() method.

The title
Now king of Glory is very popular, I believe that most people also played, then we will define a hero class, used as the father class of each hero in King of Glory. Generally speaking, a hero has a name, health, mana, initial movement speed, attack value… All we need to do is add these as class attributes as possible to the class.
Analysis of the
We look at how to define a class, how to add attributes to a class, and how to select the data type of the attributes.

The title
Since Kings of Honor heroes have a lot of stats, and they also have a lot of equipment, when we buy equipment, we give our heroes more health, attack value, movement speed, etc. Let’s define a few methods that we can use to add stats to our heroes after purchasing equipment.
Analysis of the
We’ll focus on how to define methods for our class.
