It is a "problem" with nextInt, the method only read the number and leave the <enter> so the next time you call nextLine, the <enter> being present, it will read this, so the value is empty. You need to clear the input first, simply by reading the line.

System.out.println("How many Students in class?");
int n = input.nextInt(); 
input.nextLine(); //will consume the \n
