This type of polymorphism is static or compile-time polymorphism and is also called method overloading. There is also runtime or dynamic polymorphism, where the child class overrides the parent’s method: public
Polymorphism: Addy can change behavior based on the context of the input, overloading the “+” to perform addition, or concatenation, depending on the context • Polyinstantiation: Two Addy objects (secret and top secret), with different data Coupling and Cohesion Coupling and cohesion are tw...

Java Copy In this example, we’ve created a newVehicleobject (myCar) and passed “Blue” as an argument to the constructor. The constructor then sets thecolorproperty to the passed argument, which is “Blue” in this case. Constructor Overloading ...
