Quick Answer
The answer is "int". When you call print(10) with an integer literal, Java’s method overloading resolution selects the primitive int version over the Integer wrapper type because the literal 10 is inherently a primitive int, and the compiler prefers the most specific match that requires no autoboxing. This tests your understanding of how Java handles method overloading with primitive versus wrapper types, a common topic on the Oracle Java Foundations 1Z0-811 exam. A frequent trap is assuming that autoboxing will automatically convert the literal to an Integer, but the compiler always prioritizes the exact primitive match when available. Remember the memory tip: "Primitives win without the box"—if a literal fits a primitive parameter directly, Java will not reach for the wrapper.
This 1Z0-811 practice question tests your understanding of java basics and syntax. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Given methods: void print(Integer i) { System.out.println("Integer"); } void print(int i) { System.out.println("int"); } What is output of print(10);?
Compilation error
Why wrong: Incorrect. Both methods are valid.
"int"
Correct. Exact match with int parameter.
"Integer"
Why wrong: Incorrect. Autoboxing is not used when exact match exists.
Runtime error
Why wrong: Incorrect. No ambiguity at runtime.

Correct answer & explanation
"int"
When calling print(10) with an integer literal, Java's method overloading resolution prefers the primitive int version over the Integer wrapper type because the literal 10 is a primitive int. The compiler selects the most specific matching method without requiring autoboxing, so the void print(int i) method is invoked, printing "int".
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
Oracle often tests the misconception that autoboxing will always convert a primitive to its wrapper type, leading candidates to incorrectly choose the Integer overload, but the compiler prioritizes exact primitive matches to avoid unnecessary boxing.
Detailed technical explanation
Under the hood, Java's method resolution follows three phases: first it looks for a match without boxing/unboxing, then with boxing/unboxing, and finally with varargs. Here, the literal 10 is a primitive int, so the first phase finds the exact match void print(int i), making it the most specific method. In real-world code, this distinction matters when designing APIs that accept both primitive and wrapper types, as it affects performance (avoiding unnecessary object creation) and behavior (null handling for wrappers).
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the 1Z0-811 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
