Question 22 of 481
1Z0-811 Arrays and Methods Practice Question
Which TWO statements are true about method overloading in Java?
⚠ Common exam trap
Test-takers frequently confuse method overloading with method overriding, mistakenly thinking return types must differ or that parameter counts must be identical, when in fact overloading only requires different parameter lists and the same method name.
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
✓
Overloaded methods can have different parameter lists.
Method overloading in Java allows multiple methods to share the same name but have different parameter lists (different number, type, or order of parameters). This enables compile-time polymorphism, where the compiler selects the appropriate method based on the arguments provided at the call site.
