ICSE − Q & A

/*I don't know why but there is a problem with this code.When I'm entering a number for the value of 'n',and press enter after pressing it, instead of appearing one by one, two input lines appear at once,like:
Enter name 1:
Enter name 2: (Both together,and only one value they accept).

Then, it works properly. I'm forwarding the code, anyone who can help, will be appreciated.*/
import java.util.*;
class BubSortNames
{
    public static void main(String args[])
    {
        Scanner sc=new Scanner(System.in);
        int i,j,n;
        String names[]=new String[100];
        String swap="";
        System.out.println("Enter the value of 'n':");
        n=sc.nextInt();
        System.out.println();
        for(i=0;i<n;i++)
        {
            System.out.println("Enter name "+(i+1)+":");
            names[i]=new String(sc.nextLine());
        }
        //Sorting steps.
        for(i=0;i<n-1;i++)
        {
            for(j=0;j<n-1-i;j++)
            {
                if(names[j].compareTo(names[j+1])>0)
                {
                    swap=names[j];
                    names[j]=names[j+1];
                    names[j+1]=swap;
                }
            }
        }
        //Displaying the sorted list.
        for(i=0;i<n;i++)
        System.out.println(names[i]);
    }//MAIN.
}//CLASS.
