Method Overriding Rules
Advanced Practice Question
Format: Method Overriding Rules
Which method signature correctly overrides the parent method?
Which method signature correctly overrides the parent method?
public class Parent {
public int calculate(int x) {
return x * 2;
}
}
public class Child extends Parent {
// Which override is VALID?
}
Difficulty: Hard |
Topic: Method Overriding Rules |
Cycle: 2 (Advanced)
Why This Answer?
Overriding requires: same name, same parameters, same or wider access, compatible return type. Option C matches exactly. A is narrower access (invalid). B is overloading, not overriding. D has different return type (invalid for int).
Common Mistake
Watch Out!
Confusing overriding (same signature) with overloading (different parameters).
AP Exam Strategy
Override = same signature. Overload = different parameters.
