Day 21: Generics - HackerRank 30 days of code solution
Objective Today we're discussing Generics; be aware that not all languages support this construct , so fewer languages are enabled for this challenge. Task Write a single generic function named printArray ; this function must take an array of generic elements as a parameter (the exception to this is C++, which takes a vector ). The locked Solution class in your editor tests your function. Note: You must use generics to solve this challenge. Do not write overloaded functions. Input Format The locked Solution class in your editor will pass different types of arrays to your printArray function. Constraints You must have exactly function named printArray . Output Format Your printArray function should print each element of its generic array parameter on a new line. Solution : import java.util.*; class Printer <T> { ...
