Polymorphism types in Java is/areOptionsRun timeCompile timeBoth Compile time and Run timeNone of the mentioned

The correct answer is "Both Compile time and Run time".

Java supports two types of polymorphism: compile-time polymorphism and runtime polymorphism.

1. Compile-time polymorphism: This is also known as static polymorphism. In this type of polymorphism, the decision is made at compile time. For example, method overloading is a way to achieve compile-time polymorphism in which multiple methods share the same name but have different parameters.

2. Runtime polymorphism: This is also known as dynamic polymorphism. In this type of polymorphism, the decision is made at runtime. The best example of runtime polymorphism is method overriding. In method overriding, the child class has the same method as the parent class.
