Taking correct input in array of strings

Question

My code isn't taking the first string as input. Instead it starts directly with the second one. Can anyone tell me, what am I doin' wrong?

import java.util.Scanner;
import java.util.Arrays;
class StrSort
{
    public static void main(String args[])
    {
        int size;
        Scanner s=new Scanner(System.in);
        System.out.print("\nEnter the size of the array : ");
        size=s.nextInt();
        String[] array=new String[size];
        int i;
        for(i=0;i<size;i++)
        {
            System.out.print("\nEnter string "+(i+1)+" : ");
            array[i]=s.nextLine();
        }
        Arrays.sort(array);
        System.out.print("\nStrings are sorted.");
        for(i=0;i<size;i++)
        {
            System.out.print("\nString "+(i+1)+" : "+array[i]);
        }
    }
}

The problem is that the newline after the size is not consumed.

import java.util.Scanner;
import java.util.Arrays;
class StrSort
{
    public static void main(String args[])
    {
        int size;
        Scanner s=new Scanner(System.in);
        System.out.print("\nEnter the size of the array : ");
        size=s.nextInt();
        s.nextLine();  // Consume newline left-over
        String[] array=new String[size];
        int i;
        for(i=0;i<size;i++)
        {
            System.out.print("\nEnter string "+(i+1)+" : ");
            array[i]=s.nextLine();
        }
        Arrays.sort(array);
        System.out.print("\nStrings are sorted.");
        for(i=0;i<size;i++)
        {
            System.out.print("\nString "+(i+1)+" : "+array[i]);
        }
    }
}

`Scanner#nextInt` does not read the last newline character of your input. See: http://stackoverflow.com/a/13102066/1521064 — vault, Nov 07 '14 at 10:31
