Day 21: Generics Hackerrenk Solution Java
For Explanation Watch Video:
Code:
import java.util.*;
class Printer <T> {
/**
* Method Name: printArray
* Print each element of the generic array on a new line. Do not return anything.
* @param A generic array
**/
void printArray(T arr[]){
for(int i=0;i<arr.length;i++){
System.out.println(arr[i]);
}
}
// Write your code here
}
public class Generics {
public static void main(String args[]){
Scanner scanner = new Scanner(System.in);
int n = scanner.nextInt();
Integer[] intArray = new Integer[n];
for (int i = 0; i < n; i++) {
intArray[i] = scanner.nextInt();
}
n = scanner.nextInt();
String[] stringArray = new String[n];
for (int i = 0; i < n; i++) {
stringArray[i] = scanner.next();
}
Printer<Integer> intPrinter = new Printer<Integer>();
Printer<String> stringPrinter = new Printer<String>();
intPrinter.printArray( intArray );
stringPrinter.printArray( stringArray );
if(Printer.class.getDeclaredMethods().length > 1){
System.out.println("The Printer class should only have 1 method named printArray.");
}
}
}
