This is my code for printing the random numbers in an arraylist:

public void printList()
{
    System.out.println("The numbers on the list: ") ;
    for (int i = 0 ; i < aList.size() ; i++)
    {
        System.out.print( aList.get(i) + "  ") ;
    }
    System.out.println("\n") ;                
}

How would I print every other number of this same list? By using a do-while loop?

Put additional if statement inside your for block which would check for parity: if (i % 2 == 0) { System.out.print(... }

Above approach is ineffecient. Just increment the index by 2

public void print()
{
    System.out.println("The numbers on the list: ") ;
    for (int i = 0 ; i < aList.size() ; i+=2)
    {
        System.out.print( aList.get(i) + "  ") ;
    }
    System.out.println();                
}
