Java Code:

System.out.println(String word);

What is wrong with the above line of code? What similar problem do you have in your code? Fix the first error and the second will probably disappear. For the third error it says it cannot find the variable 'i'. Where have you declared it?

I figured out the first one but I seriously can't see what you mean with the second, and I feel stupid. >.>

Java Code:

public void drawHor()   {
    // step 8:
    // draw horizontal bar graph (one line per roll value)
    for(int d = 1; d < values.length; d++)
        System.out.print("Count " + d + ":" + "\t" + values[i]);
    System.out.println("*");
}

In the first print statement you are using the variable 'i' to access an element of the values array. Where have you declared the 'i' variable?

I fixed that one already. The other two (step 5) is where I am stuck. That error was from me not paying attention. I honestly don't know how to fix the other two.

I'm confused. You keep saying you have fixed things. What are your current errors?

Did you read the error messages? You are making a static call when the method is not static. What does that mean? Imagine you have a Person class. Each Person has a name. There are billions of Person objects in the world. If you say "print Person.name" which name should be printed? Your error relates specifically to this line:

Java Code:

Histogram.drawHor();

Surely you can work it out yourself.

As for the warnings you can either fix them or ignore them. If you code only has warnings and no errors, it will still compile and run. Ideally you would fix them in the long run but it is upto you.
