Java: Strategy Pattern

By using polymorphism, it replaces conditional logic with strategy objects.

The Strategy Pattern helps eliminate complex 'if/else' or switch statements by using polymorphism to select the behavior at runtime. This pattern delegates the responsibility of choosing the algorithm to the strategy object. For example, instead of using an 'if/else' to determine which discount to apply in a checkout process, you could use the Strategy Pattern to switch between different discount strategy objects, each implementing a common interface.
