Introduction To Array

 package arrays;

import java.util.Scanner;

public class ArrayIntro {

public static void main(String[] args) {


/*

int[] marks;

marks = new int[5];

*/

//int marks[] = new int [5];

//ALL ARE SAME


int[] age = {2,4,8,16,32};

double[] percentage = {1.0,3.14,4.6,78};

Scanner sc = new Scanner(System.in);

while(6>age.length) {

int n = sc.nextInt();

System.out.println(age[n-1]);

}}}
