Question

I’m trying to take string in input using Scanner.
But it asks me more strings that expected: shouldn’t with this code ask 5 strings?

public void go()
{
    Scanner sc=new Scanner(System.in);
    ArrayList<String> list=new ArrayList<String>();
    String temp=new String();
    Integer i=new Integer(0);
    while(sc.hasNextLine() && i<5)
    {
        temp=sc.nextLine();
        list.add(list.size(),temp);
        i++;
    }
}

If I try to run it it asks me 6 strings before the console stops to take input.
But i at the beginning is zero, it gets incremented 5 times before becoming 5.
So why it also remain in while when i is 5?

Solved: Both methods solved the problem.

Answer 1

If i == 5 still a sc.HasNextLine() is called. Repair:

while (i < 5 && sc.hasNextLine())

P.S. do int i = 0;
