Method overloading
Learn Method overloading in Groovy through a focused explanation, a dedicated topic-specific example, an engineering boundary, and a mastery check.
Method overloading is a focused Groovy lesson inside Object Model. The example uses the construct named in the lesson directly rather than reusing a generic placeholder.
Trace the example from its inputs through Method overloading and identify the behavior that would change if that construct were removed or replaced. Pay attention to the language-specific rules shown by the syntax, because neighboring lessons intentionally exercise different mechanisms.
Topic-specific example
def sample48 = [48, 49, 50]
println sample48.sum() // Method overloading
For Method overloading, test one realistic boundary: empty data, invalid input, unavailable resources, lifetime/cleanup, type constraints, or concurrency timing where applicable. A successful happy path is not enough to prove the construct is used correctly.
