Why is it not allowing me to input just 5 numbers, when I run it, it allows me to input 6

import java.util.Scanner;

public class Lab11d
{
    public static void main (String[] args)
    {
        Scanner in = new Scanner(System.in);
        double [] anArray;  // declares an array of integers
        anArray = new double [5];        
        int min=0;       

        //Initalizes the array values//
        System.out.println ("Enter 5 numbers of your choosing"); 

        double a = in.nextDouble();       
        for ( int count=0; count < 5; count++)
        {
            anArray[count] = a;
            a = in.nextDouble();
        }

        //Prints array values//
        for (double value : anArray)
            System.out.println ("Element at index " + (min++) + ":"+ value + "" ); 
    }
}

It runs, but I only want to input 5 numbers, not sure what I am doing wrong. It allows me to enter six with like a limit of 5, curious how to change it please

You are accepting a double first time and then iterating through a loop which accepts 5 doubles i.e. in total you are accepting 6 doubles.

You have to edit your for loop as,

    for ( int count=0; count < 5; count++)
    {
        anArray[count] = in.nextDouble();
    }

Because you get one double before your loop. Change it to something like

// double a = in.nextDouble();       
for (int count=0; count < 5; count++)
{
    double a = in.nextDouble();
    anArray[count] = a;
}

or eliminate a altogether like

for (int count=0; count < 5; count++)
{
    anArray[count] = in.nextDouble();
}
