java.util.function.Function interface?
Which statement is true about the single abstract method of the void.
The java.util.function.Function interface has a single abstract method, apply, which accepts one argument and produces a result. The argument and result can be of any data type, making the interface generic and flexible. This allows it to take an input of type T and return a result of type R, which could be any data type.
Answer is D The function method accepts type T argument and return a generic type R, which could be any data type.
Function<String, Integer> toInteger = Integer::valueOf So it takes one argument and return as result one of any types
Answer is D. The function method accepts type argument and return a generic type, which could be any data type.
D is true.
