For Explanation Watch Video:
import java.io.IOException;
import java.lang.reflect.Method;
class Printer
{
//Write your code here
public <T> void printArray(T[] arr){
for(int i=0;i<arr.length;i++){
System.out.println(arr[i]);
}
}
}
public class Solution {
public static void main( String args[] ) {
Printer myPrinter = new Printer();
Integer[] intArray = { 1, 2, 3 };
String[] stringArray = {"Hello", "World"};
myPrinter.printArray(intArray);
myPrinter.printArray(stringArray);
int count = 0;
for (Method method : Printer.class.getDeclaredMethods()) {
String name = method.getName();
if(name.equals("printArray"))
count++;
}
if(count > 1)System.out.println("Method overloading is not allowed!");
