Creating a simple StringRevert program - Java

Question

I am trying to create a simple String Revert program that does the following:

Prompts the user for an integer n
Creates an array of n Strings
Keeps reading character strings from user and stores them in the array, until the end of the array or user types "quit"
Prints the strings from the array in reverse order excluding empty slots

Here is my attempt so far:

-However, when i take input and make the size 4, the buffer only reads 3 strings and stops rather than 4.

import java.util.*;
import java.io.*;

class StringRevert {

    public static void main(String[] args) {

        String myArray[];

        Scanner Scan = new Scanner(System.in);
        System.out.println("Enter Number: ");
        int size = Scan.nextInt();

        myArray = new String[size];

        for(int i=0; i<myArray.length; i++) {
            myArray[i] = Scan.nextLine();
        }
    }
}

put Scan.nextLine(); before starting of loop – Pratik Apr 02 '15 at 10:26 — Pratik, Apr 02 '15 at 10:26

You need to put Scan.nextLine(); before starting of for loop.

public static void main(String[] args) {

    String myArray[];

    Scanner Scan = new Scanner(System.in);
    System.out.println("Enter Number: ");
    int size = Scan.nextInt();

    myArray = new String[size];
    Scan.nextLine();
    for(int i=0; i<myArray.length; i++) {
        System.out.println("Enter String");
        myArray[i] = Scan.nextLine();
    }
}
