Question 102 of 481
1Z0-811 Arrays and Methods Practice Question
Which statement about method overloading with array parameters is true?
⚠ Common exam trap
Oracle often tests the misconception that varargs (int...) and arrays (int[]) are distinct types for overloading, when in fact they are treated identically by the compiler.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A method with parameter int[] and another with parameter Integer[] are overloaded.
Method overloading requires methods to have the same name but different parameter lists. int[] and Integer[] are different parameter types (primitive array vs. wrapper class array), so they satisfy the overloading requirement. The return type is irrelevant for overloading.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A method with parameter int[] and another with parameter int... are overloaded.
Why it's wrong here
They are considered the same signature, causing a compilation error.
- ✓
A method with parameter int[] and another with parameter Integer[] are overloaded.
Why this is correct
int[] and Integer[] are different types, so they can be overloaded.
- ✗
Two methods with the same name and same parameter types but different return types are considered overloaded.
Why it's wrong here
Return type alone does not distinguish overloads.
- ✗
A method with parameter int[] and another with parameter int[][0] are overloaded.
Why it's wrong here
int[][0] is not a valid type.
