passing code with behavior parameterization

Behavior parameterization allows you to pass a piece of logic or behavior to another method instead of hard-coding the behavior inside it. This makes code more flexible, reusable, and easier to maintain. In Java, this approach is commonly implemented using functional interfaces and lambda expressions. In this section, you’ll learn how to replace repeated conditional logic with parameterized behavior. You’ll also see practical examples showing how this technique can simplify filtering, sorting, validation, and other common programming tasks.
