One name, many behaviors.
Polymorphism means "many forms" — the ability of one method or object to behave differently based on context. In Java, it's one of the four pillars of OOP, alongside encapsulation, inheritance, and abstraction.
↳ Polymorphism lets the same method name trigger different behaviors depending on context.
Same name, different parameters.
Method overloading is compile-time polymorphism. Multiple methods share the same name but have different parameter lists — differing in count, type, or sequence.
↳ Overloading is resolved by the compiler based on method signature.
See overloading with different types.
↳ The compiler picks the right overloaded method based on arguments passed.
Polymorphism in Java is a core OOP concept enabling one method name to exhibit multiple behaviors. It manifests as compile-time polymorphism through method overloading and runtime polymorphism through method overriding,...

29 questions laddered from warm-up to topper-level, each with an explanation. A taste:
What does polymorphism mean in Java?
BeginnerMany forms
Polymorphism literally means 'many forms' — the ability of one method or object to behave differently based on context.
Which type of polymorphism is method overloading?
BeginnerCompile-time polymorphism
Method overloading is resolved by the compiler at compile time, hence it's compile-time polymorphism.
Which of the following can differentiate overloaded methods?
IntermediateParameter list (number, type, or order)
Overloaded methods must have different parameter lists; return type alone cannot differentiate them.
What is the output of the following code? ```java class Parent { void show() { System.out.println("Parent"); } } class Child extends Parent { void show() { System.out.println("Child"); } } Parent p = new Child(); p.show(); ```
IntermediateChild
At runtime, the actual object type (Child) determines which method is called, so it prints 'Child'.
