That also means that you don&#8217;t need the variables a-f in the Head class.<\/p>\n<pre><code>public class Head {\npublic static void main(String[] args) {\n\n    \/\/int a=0;\n    \/\/int b=0;\n    \/\/int c=0;\n    \/\/int d=0;\n    \/\/int e=0;\n    \/\/int f=0;\n\n    for(int i=0; i&lt;5; i++){\n        int dice1 = 1 + (int)(Math.random() * ((6 - 1) + 1));\n\n        Dice diceObject = new Dice(dice1    \/*, a, b, c, d, e, f*\/  );\n        diceObject.countNumbers();      \n        diceObject.saveResults();\n    }\n    System.out.println(\"A B C D E F\");\n    Dice.displayResults();\n} }\n<\/code><\/pre>\n<p>Again, the snips of code not needed are commented out. <\/p>\n<p>The next thing is that when you write the code<\/p>\n<pre><code>System.out.println(diceObject);\n<\/code><\/pre>\n<p>that doesn&#8217;t work because diceObject is an instance of a class (Dice) and it isn&#8217;t a variable.<\/p>\n<p>The way I got everything to work was by having the variables sa, sb, sc, sd, se, and sf added.<\/p>\n<pre><code>private static int sa = 0, sb = 0, sc = 0, sd = 0, se = 0, sf = 0;\n<\/code><\/pre>\n<p>I added these so that the results from each time the loop runs will be saved. I created a void to do this called saveResults(); The variables had to be static because the void was static too. I made the displayResults void (i&#8217;ll get into that later) static so it could be accessed from a the Head class.<\/p>\n<pre><code>public void saveResults() {\n    sa += a;\n    sb += b;\n    sc += c;\n    sd += d;\n    se += e;\n    sf += f;\n}\n<\/code><\/pre>\n<p>The += just means to add;<br \/>\nThe last thing I did was make the displayResults void. It just displays the variables sa-sf using System.out.println();<\/p>\n<pre><code>public static void displayResults() {\n    System.out.println(sa + \" \" + sb + \" \" + sc + \" \" + sd + \" \" + se + \" \" + sf);\n}\n<\/code><\/pre>\n<p>This all went together to make the final product.
