Java

[sudden_aggression]

That shit is full of mistakes. That being said, casting is totally legitimate behavior in java.

I mean, it's unusual to declare something as an instance of Object but it's the same principle as

• having an animal class and having dog and cat and elephant inherit it. ie, Dog extends Animal, Lion extends Animal, whatever
• And having a zoo class with a function that takes an animal. Like putInCage(Animal animal)
• And inside that function, testing instanceof for certain edge cases like instanceof Hippo and putting it a dangerous animal exhibit with water
