So it would be something like,
Code:
ArrayList<Actor> valLocs = getGrid - getOccupiedLocations.

Yeah, my idea for it was to make a new ArrayList.
So it would be something like,
something along those lines... -
Anyone know this year's GridWorld code? I need help on making a class.
...Code:public class fly extends Actor { public fly() { setColor(Color.BLACK); } public fly(Color flyColor) { setColor(flyColor); } public void act() { if (canMove()) { move(); } else { turn(); } } public void move() { if (getGrid() == -
Yeah, I did it like that. It works. Thanks...Leave a comment:

yeah. i got that. what about the rset?...Leave a comment:

I check whether or not there are spaces to the left and to the right of it, if there is, its a single digit and i keep checking to get the entire number, or I can check if there is a letter to the left or to the right of it...Leave a comment:

yeah, i forgot to put ret string in the other method. For a string like "7 11", it has a space in it, so I want to condense it. Yeah, i see what u mean.
First I would check each char and see whether or not it is a int. then i have to do something ot check whether or not it is a double digit or a single digit, im having some trouble there...Leave a comment:

Need help with a few javabats
hi, i need help with a couple of javabats.
1) http://javabat.com/prob?id=String3 .sumNumbers
...Code:public int sumNumbers(String str) { String retString = ""; String m = ""; int temp = 0; for (int k = 0; k < str.length(); k++) { char c = str.charAt(k); if (Character.isLetterOrDigit(c)) { -
I see. Yeah, ArrayLists are much easier to use.Leave a comment:

i was thinking about using an array.... would that help...Leave a comment:
-
Heh, yeah.
But my idea, in code, for it is to make different variables to store each number. But that would take forever....Leave a comment:

I would tally each number that appeared and then see which one appeared the most.
To determine the mode, I have to see which number appears the most....Leave a comment:

from 0 - 99
I would calculate the mode by hand by doing:
Storing each value into a variable and just adding 1 to it everytime i pass it. Then i print out the one that has the highest number.
But doing it that way would take forever....Leave a comment:

Heh, never mind, I got it.
Okay, now here is the hardest part
I need to find the mode of the Array List, meaning the number that appears the most...
...Code:import java.util.ArrayList; import java.lang.Math; import java.text.DecimalFormat; public class Statistics { public static void main(String args[]) { DecimalFormat df1 = new DecimalFormat("####.00");Leave a comment:

I did the Standard Deviation, but I want to round this off to 2 decimal places
...Code:import java.util.ArrayList; import java.lang.Math; public class Statistics { public static void main(String args[]) { ArrayList <Integer> intList = new ArrayList <Integer>(); double count1 = 0.0; double sdTemp = 0.0; for (int k = 0; k < 10; k++)Leave a comment:

Ooh, thanks. I got it working.
The next part of my program needs to find the Standard Deviation of the Array List.
This is how to find it
a. Find the average of the list of numbers.
b. Determine the difference of each number from the average, and square each difference. Sum all the differences.
c. Divide this sum by (the number of values - 1).
d. Take the square root...Leave a comment:

I thought that by default ArrayList <integer> intList = new ArrayList <integer>() has the size of 10....
So how do I set the size?...Leave a comment:
-
oh
count is 0.0
and intList is 0
but why? I am adding random numbers to the Array List. and the () at the end of the declaration of the Array List should equal 10. So intList.size() should be 10. and count should be all the random numbers added together.......Leave a comment:

...Code:import java.util.ArrayList; public class Statistics { public static void main(String args[]) { ArrayList <Integer> intList = new ArrayList <Integer>(); int size = intList.size(); for (int k = 0; k < size); k++) { intList.add((int)(Math.random()*100)); } double count1 = 0; for (int i = 0; i <Leave a comment:

Uses of Array List
Hey. I'm having some difficulty in Array lists. I have to find the average of all the numbers in an array list. That's my first task. My second one is to find the mode of all the numbers, meaning the number that shows up the most. And the third one is to find a standard deviation, which I will get to later.
Anyway, right now I'm doing Average.
...Code:public class Statistics { public static void main(String
