Which of the following is a type of polymorphism in Java?Select one:Compile time polymorphismMultiple polymorphismExecution time polymorphismMultilevel polymorphism
Solution
The correct answer is: Compile time polymorphism.
In Java, there are two types of polymorphism: compile-time polymorphism and runtime polymorphism.
Compile-time polymorphism is achieved by method overloading. In method overloading, multiple methods share the same name but have different parameters (either different types or a different number of parameters).
Runtime polymorphism is achieved by method overriding. In method overriding, a subclass provides a specific implementation of a method that is already provided by its parent class.
The other options provided (Multiple polymorphism, Execution time polymorphism, Multilevel polymorphism) are not recognized types of polymorphism in Java.

Java classes support runtime polymorphism. Which statement describes what is possible with runtime polymorphism?Instruction: Choose the option that best answers the question. Answer ChoicesMultiple implementations can exist for methods with the same name, with the same input arguments and return valuesCalls to overridden methods are resolved at runtime, hence methods invoked on an object will use the correct implementation based on object typeExactly one implementation can exist for a method with a certain name, and all derived classes have access to these implementationsMethods invoked on objects of the base class type will invoke the base class method implementations
