Advanced Practice Question
Format: Method Overriding vs Overloading
Which methods are in class Child?
Which methods are in class Child?
public class Parent {
public void work(int x) {
System.out.println(x);
}
}
public class Child extends Parent {
public void work(int x) {
System.out.println(x * 2);
}
public void work(double x) {
System.out.println(x);
}
}
Difficulty: Hard |
Topic: Method Overriding vs Overloading |
Cycle: 2 (Advanced)
Why This Answer?
work(int) has the same signature as Parent's method so it overrides. work(double) has different parameters so it overloads.
Common Mistake
Watch Out!
Confusing overriding (inheritance + same signature) with overloading (same name, different parameters).
AP Exam Strategy
Override = replace parent's method. Overload = add another version with different parameters.
