Boolean in Math
I was just reading through some old presentations and came across a concept of using boolean results in math. The example was...
NewSales = Sales * @ISUDA("NewMbr");
I would imagine that the value would come back "TRUE" or "FALSE". Does "TRUE" evaluate to a "1" and "FALSE" to a zero?? Has anyone ever used this before??
Thanks,
Kevin
Thanks Glenn. Yes, it was a Roske presentation.
I was unaware that logic was numeric, but I guess it makes sense.
Any idea if a boolean attribute type could also be used in math??
CaffeinatedSales = Sales * @ATTRIBUTEBVAL(Caffeinated);
If this is so, I guess I could extrapolate that "True"/"False" would always evaluate to 1/#Mi.
Thanks

Images disappearing / being painted over
Hi,
Not especially familiar with images and am having issues with images being painted over when ever I move or adjust the size of my GUI. I built a majority of the GUI using the Form Designer included with Netbeans.
Would really appreciate any advice, happy to include more detail if required.
Cheers,
Tim

Going nuts over modulo of two doubles
consider:
double x=2.0;
double y=0.1;
double z=x%y;
boolean perfectFit = (Math.round(x/y)==x/y);
System.out.println("x="+x+",y="+y+",z="+z+",perfectFit="+perfectFit);
// surprisingly (at least for me),
// while perfectFit is true (as expected), z is not zero at all:
x=2.0,y=0.1,z=0.0999999999999999,perfectFit=true
am I missing something?What happens is quite normal and you will understand this if you try:
public class Modulo {
public static void main (String [] args) {
double x = 2.0;
double y = 0.00001;
double z=x%y;
boolean perfectFit = (Math.round(x/y)==x/y);
System.out.println("rounded: "+Math.round(x/y));
System.out.println("not rounded: "+x/y);
System.out.println("modulo: "+z);
System.out.println(perfectFit);
}You see Math.round(double) returns a long and you play with double. That means that you lose a bit of presision here... In the above example this becomes obvious for a big number.
Hope that helped

So I have a MC thats throwing me for a loop. As stated its giving me the 1152 error code.

Help with java (2 simple classes)
would anyone be able to help me with some questions about two very short java classes?
i have come up with some answers of my own, but yeah, i'm not sure how correct my answers are....
the 4 questions are:
1. The data attributes m, n and grid in the HeatGrid class are declared private, and methods
such as gridHeight(), gridWidth() and copyGrid() are provided to extract their value. Why
is the better class design than simply declaring those attributes as public?
My answer: So other classes accessing them cannot modify those data atributes, i am not sure why this is better class design.
2. Why must the (global) constants in HeatSim.java be declared static ?
My Answer: because HeatSim is what you run first and so you don't create a HeatSim object, you just access its methods, thus the need to make them static.
3. Assuming HeatGrid has been fully implemented, during the execution of the statement
HeatGrid = new HeatGrid(inGridFile), how many objects of HeatGrid, double [][] and
Scanner are created?
My Answer: 1 HeatGrid object, 1 doulbe[][] object and 1 scanner object
Which of these objects must still exist after the statement completes execution?
4. For each of the classes HeatSim and HeatGrid, identify the client and supplier classes
(including library classes).
My Answer: So far this is what i have done. for the HeatSim class, i said that the supplier classea are:
double
int
boolean
String
Math Class
viewgrid class
array

Wrong code analysis on "unreachable statement" for nested loops
Try this with JavaFX 1.2 (NetBeans 6.5.1)
function foo():Void {
for (i in [0..<10]) {
for (j in [0..<10]) { // be marked as unreachable statement
if (match()) {
break;
return; // I just want to get out
// break goes here
}It shows "unreachable statement" at the second 'for'.
Right now I just change "return;" to "if (true) return;" to get it pass.I agree it is a bug at the compiler level. If I do your change and add println of i and j, I get a trace on j, obviously.
You should file a bug report at [Jira / Kenai|http://javafx-jira.kenai.com/] (or I can do if you don't want to create an account).
[EDIT] Uh, no, it is a known problem: [Bogus 'Unreachable statement' error|http://javafx-jira.kenai.com/browse/JFXC-3323], I will add this thread as a comment.
A more complete use case:
function foo(): Void {
for (i in [ 0 ..< 5 ]) {
println("I {i}");
for (j in [ 0 ..< 5 ]) {
println("J {j}");
if (match()) {
break;
println("Some operation in the inner loop");
if (true) return;
// break goes here
function match(): Boolean { return Math.random() > 0.5; }
foo();Now, the inner loop isn't really necessary, we never go beyond 0 for j... But technically, there is no unreachable statement, unless it means we never go up to 5 in the inner loop. In this case, Robert Field is right, the error message should be clearer.

I'm trying to replace all even numbers in a string with odd numbers that are produced from a random generator. I have somewhat of an idea of how to do it as far as creating an array of 5 characters(1,3,5,7,9) and then implement the math.random to take random numbers from that array. i just dont know how to execute that. for example:
"adam123456789" -->should be "adam153157739"
whereas, the underlined(5,1,7,3) should be random numbers(i just picked these for an instance). is it possible to do any form of :
Methods...
char [ ] ary = {1,3,5,7,9};
String line = "adam123456789";
line = line.replaceAll("[0,2,4,6,8]", Math.round(Math.random()*[ary]));
return line;**i'm a beginner, so i dont really know what im talking about. just seeking help. thanks!ok. this is the class with all of my methods in there. just excuse the rest of it..

Greetings,
I need a boolean control that will write measured data to a text file while it is lached and do nothing while it is unlached (which is simple). However, I also need it to display a dialog box when it is first lached to prompt the user to either append to an existing file or create a new file. It should not contiously prompt the user to select new or append while it is lached. It should only reprompt if the boolean has been unlached and relached.
Any ideas? I have tried several different approaches but everything that I have done has either not worked at all or contiuously prompts while lached.
I know it will involve a shift register and at least one boolean comparison but I cannot figure out the arrangement.
Thanks in advance.
Solved!
Go to Solution.Hi BB,
looked at the Pt-by-Pt functions. There you will find a ready-to-use VI to detect edges of a boolean signal!
Or use that boolean math: RisingEdge = signal[n] AND NOT(signal[n-1]). (Here you need the already mentioned boolean function with a shift register...)
All you need is opening the dialog for rising edges of the boolean signal...
Best regards,

Is there a way to create a math.random that doesn't overlap movieclips?
Hi,
Actually I have two questions. I am creating a memory sequence game and I was wondering:
1. Is there a way to random position movieclips on the stage without having them overlap each other?
2. Is there a way to have flash draw a vector line from one clip to another in sequence and then have the user retrace what flash did? I have 6 movieclips on the stage, each with their own instance (ex. obj1_mc, obj2_mc, etc.). Is there a way to tell flash to always draw a line between movieclips in sequence even though the movieclips are randomly placed on the stage?
Thanks,
OJsure.
1. the easiest way to position objects without over-lapping, IF you can assume it will always be possible, is to use something like:
var mcA:Array=[your movieclips]
var index:uint=0;
positionF();
function positionF(){
// assuming top-left reg points of your movieclips
mcA[index].x=Math.random()*(stage.stageWidth-mcA[index].width);
mcA[index].y=Math.random()*(stage.stageHeight-mcA[index].height);
var hitBool:Boolean=false;
for(var i:int=0;i<index-1;i++){
if(mcA[index].hitTestObject(mcA[i])){
hitBool=true;
break;
if(hitBool){
positionF();
} else {
index++;
if(index<mcA.length){
positionF();
} else {
// positioning complete. do whatever
2. you can use the graphics class to draw dynamic lines. -
Boolean error with a If else statement
Hello, i am new to java, and the only other programing language i have used is pascal, and compared to java its ALOT different any ways my problem. I am trying to write a simply little program which random selects a number between 1 and 10, i did that fine got to show that on screen with no probelm . Next i wanted to but in a if else statement, depending which numbers was selected it would show a different message this is where i am getting a probelm, here is the code for the whole thing:
// randomColour
import javax.swing.JOptionPane;
public class randomColour {
public static void main ( String args [])
int value;
value = 1 + ( int ) ( Math.random() * 10 );
if (value = "1" )
System.out.println("Green");
else
System.out.println("Blue");
System.exit( 0 );
} // end mainWhen i try to Compile it comes up with error saying required:boolean why is this? and what can i do to change to fix it?A single = is used to indicate assignment. You are testing for equality which requires ==. Also, "1" is a String. Value is an int. Changeif value = "1" to if value == 1Mark

Use boolean array to perform set operations
I am currently taking a computer science class that uses Java as the language of choice. I have no prior experience with Java. We have a homework assignment in which we are supposed to use a boolean array to implement set operations. We have to create a method that inserts an integer into the array, another that deletes an integer element, and several others. I am confused as how to do this with integers, as it is a boolean array. The datr for this class is:
private boolean base[];The constructor is:
public largeset(int size){ }We then have to create a method that inserts an integer into the array:
public void insert(int i){ }And one that deletes the element:
public void delete(int i) { }I am unsure how to do this using a boolean array. If it were an integer array I would not have any trouble, but I get an error when trying to insert/delete an integer from the boolean array. Can anyone help point me in the right direction? I would prefer advice only, not the actual code, as this is a homework assignment, and I would like to create the code myself so I actually know what I am doing. Thanks.This is the assignment exactly as posted on the course website:
In this homework, we will use a boolean array to implement various set operations. Please create a class called largeset that supports set operations of any number of elements. The data of this class is
private boolean[] base;The constructor of the class is
public largeset(int size); // create a boolean array of size "size" and store it in "base"The methods of the class are:
public void insert(int i); // insert number i into the current set, where 0 <= i < base.length
public void delete(int i); // delete number i from the current set, where 0 <= i < base.length
public boolean member(int i); // test if i is in the set
public largeset union(largeset B); // return the union of two sets
public largeset interset(largeset B); // return the intersection of two sets
public largeset subtract(largeset B); // return the subtraction of two sets
public largeset complement(); // return the complement of the current set
public boolean subset(largeset B); // test if the current set is a subset of set B
public int cardinality(); // return the number of elements in the current set
public String toString(); // return a string which is a printing of the current setThen create another class called testset that uses the largeset class. At first, please create the following two sets:
X = { 1, 3, 5, 7, ..., 999 };
Y = { 9, 18, 27, 36, ..., 999 };
Please perform the following tests:
1. display the cardinalities of X and Y, respectively.
2. display the content of substraction of Y by X.
3. display the square root of the sum of all the elements of X (Math.sqrt(x) will return the square root of x in double type).
4. For every pair of distinct elements x and y in Y, compute the sum of (Math.max(x, y) - Math.min(x, y)) (or equivalently, Math.abs(x - y)), and report this sum. -
Implementing Boolean operators during find object for qualification
Hi Team
We would like to maintain requirements profiles for PD object (position,job etc.) in terms of qualifications (Q) using complicated boolean operators , for example :
((Q=English>4 OR (Q=French=5 and Q=Spanish>2)) OR (Q=German=6 and english<3) and Q=education # 2
The complicated boolean operators could be also : range,excluded from the range,equal,not equal,not exits.
We would like to execute the search for qualification ,profile matchup based on this complicated boolean requirments profile.
Is there any custom development or configuration to make this happen ?
Best Regards
DrorIs this still true if the Collection generics elements are an interface type? For example, in the
code I sent earlier, I have:
/** The authorities granted to this account. */
private Set<Authority> authorities;
But Authority is an interface that is implemented by the DefaultAuthority class (maybe others
eventually). I was under the impression that in this situation, the metadata does have to provide
the actual type that will be in the collection.
But even if it works in Kodo, one of the requirements of my project is that the JDO implementation
be swapable with JPOX. When I started working on it, both Kodo and JPOX were at a much earlier stage
of implementing JDO 2, and if I recall correctly, JPOX required the implementation class (though I
don't know if it had to be fully qualified). I'm not sure that requirement has been removed from
JPOX yet, though I haven't checked in a while.
Thanks for your help with the default value settings though. Is there any place where I could have
found that behavior documented (Kodo docs, JDO2 spec, etc.)?

p.s. You don't need to set the element-type in metadata if you're using
Java 5 generics; we can get the element type from the field declaration.
Also, when you do have to declare an element-type in metadata, you
don't need to fully qualify the class name if the element class is in
the same package as the field's owner (the current <package>), or in
java.util, java.math, java.lang. -

-
If i have this code:
var test: Boolean;
test = false;
if (2 == 2 == 1)
test = true;
trace (test);
Result: true.
var test: Boolean;
test = false;
if (2 == 2 == 2)
test = true;
trace (test);
Result: false
var test: Boolean;
test = false;
if (2 == 2 == 3)
test = true;
trace (test);
Result: false.
Why is that?This is not a Math issue, it is a matter of how a condfitonal test is carried out. Conditions are tested as pairs (with a left to right hierarchy unless otherwise arranged using parentheses), meaning for 2 == 2 == whatever, first the test is performed to see if 2 == 2 ?, which is true, meaning the result evaluates as a "true". Then the next comparison is performed using the result of the first... which would be... true == whatever ?. which depends on "whatever" is. A 1 evaluates as true as far as logic goes, but any other number does not, so true == 1 = true, true == 0,2,3,4,5.... = false
You will find nothing passes the test if you reverse the order of the numbers.
If you want to do compound conditional tests you are best to do it in pairs and/or use parentheses to define the order in which evaluations are managed. -
