Question
Will the following class compile?
public final class Algorithm {
public static <T> T max(T x, T y) {
return x > y ? x : y;
}
}
Select one:
- a. No
- b. Yes
Solution
Break Down the Problem
- The code provided is in Java and consists of a generic class with a static method.
- The comparison operator
>
is used, which must be checked for compatibility with the generic typeT
.
Relevant Concepts
- In Java, the
>
operator cannot be used with generic types unless they are bounded by types that support the ordering. - Primitive data types such as
int
,float
, etc. can be compared using>
, but generic types would require implementing theComparable
interface.
Analysis and Detail
- The method definition states
public static <T> T max(T x, T y)
, butT
is not constrained to a type that supports the>
operator. - Without having a bound on
T
, such as declaring it asT extends Comparable<T>
, you cannot directly apply the>
operator, leading to a compilation error.
Verify and Summarize
- Since the comparison
x > y
is invalid for generic types without appropriate bounds, the code will not compile.
Final Answer
a. No
