Explanation

#white-Compile-time polymorphism is achieved #white-using method overloading.

Code Example

int add(int a, int b) { return a + b; }
double add(double a, double b) { return a + b; }

Explanation

#white-Runtime polymorphism is achieved using #white-method overriding.

Code Example

class A { void show() { System.out.println("A"); } }
class B extends A { void show() { System.out.println("B"); } }

Explanation

#white-In compile-time polymorphism, method #white-resolution happens at compile time.

Code Example

Calculator c = new Calculator();
c.add(10, 20);

Explanation

#white-In runtime polymorphism, method call #white-depends on object type at runtime.

Code Example

A obj = new B();
obj.show();

Explanation

#white-Overloading requires different method signatures.

Code Example

void print(int a) {}
void print(String a) {}
