HELP?! I don't know why this does not work  :(((((

if (mousePressed("ticket.jpg")==true) {

     value ++;

side lengths of the quadriliateral is a,b,c,d

I know how to get the Perimeter, but i don't know how to write the code for the area...

Do i just need the side lengths? or do i also need angles?

 

 

public class Quadrilateral
{
    double a;
    double b;
    double c;
    double d;
    public Quadrilateral(){
        a=0;
        b=0;
        c=0;
        d=0;
    }
   
    public Quadrilateral (double q, double w, double e, double r){
        a=q;
        b=w;
        c=e;
        d=r;
}
   
public double getSideA(){
    return a;
}

public double getSideB(){
    return b;
}

public double getSideC(){
    return c;
}

public double getSideD(){
    return d;
}

public void setSideA(double q){
    a=q;
}

public void setSideB(double w){
    b=w;
}

public void setSideD(double r){
    d=r;
}

public void setSideA(double q){
    a=q;
  
}

public double Perimeter(double p){
    p=a+b+c+d;     
    return p;
    }

    public double Area(){
        return
    }
   
       public String toString(){
         return "Sides: " + a + b + c + d ;
    }
   

don't know if i can post this here, im using bluej...

So I need to create two classes: 1 class for a rectangle and 1 class for a circle with all necessary variables, constants, and methods.

And I'm stuck on :

 

public double calculatePerimeter ( double p){

p=2.0*(x+y);

return p;

}

 

(this is in my main class that controls the other classes)

 

and in my other class "Shape" I tried to system.out.print that and it doesn't work

I also have a string toString function...

not sure if its my syntax or something else

help?

 

say i want to read the every third line of my external txt file

how would i write the code?

I'm trying to make an array that stores all the names, and another array that stores the # of votes for each name

from an external txt file

the txt file contains all words (voting results)

 

so everytime the system reads a name, it searches the name array to see if the name was registered before, if it was, then you just add one to the #of votes of this person, and if not, then put the name in the names array then you make the votes for that person = 1.  

I'm kinda confused to how to write the syntax for this array loop

if the name is not registered before, (when the teacher changes your txt file) how can you record it into your names array and add one each time it appears?

hi! i am totally new to processing, and this is the first project i'm doing

so... im trying to get data from a txt file, and the txt file contains all words (voting results)

something like:

"Name: Amey"
"Voted For: Stephen Harper"

 

"Name: Usman"
"Voted For: Thomas Mulcair"

 

these results display fine underneath my code (by using println)

but i'm having trouble trying to record how many votes each person has, and convert it to a number percentage and display it on a pie chart.

Anyone help?!

Here is the code I have now:

PFont my_font;
String result;

float diameter;
int[] angles = { 144, 36, 36, 72, 72};
color[] MyOwnColor = {
  color(133, 130, 149), color(237, 213, 117), color(240, 174, 232), color(183, 245, 222),
  color(75, 219, 167), color(255, 250, 106), color(240, 92, 114),
  color(157, 144, 250), color(144, 215, 250)
} ;

float lastAngle = 0.0;

void setup () {
size (1000,700);
background(215);
smooth();
//ellipse(300, 360, 500, 500);
my_font=loadFont("TimesNewRomanPSMT-48.vlw");
textAlign(LEFT);
noLoop ();
diameter = min(width, height) * 0.75;

stroke (0);
fill (255);
rect (650,90,280,350);

}

void draw ()
{
  textFont (my_font,26);
 
  fill (0,0,0,200); //last num means transparency
  text("Results for Federal Elections", width/6, height/11);
   textFont (my_font,15);
    fill (0,0,0,150);
  text("© 2013 TTT",872,690);

 

    for (int i = 0; i < angles.length; i++) {
    //fill(angles[i] * 3.0);
    fill (MyOwnColor [i]);
    arc(300, 360, diameter, diameter, lastAngle, lastAngle+radians(angles[i]));
    lastAngle += radians(angles[i]);
    }

    String[] vs_results = loadStrings("FederalResults.txt");
    println("there are " + vs_results.length + " lines");
    for (int i=0; i < vs_results.length; i++) {
    println(vs_results[i]);
   
   

     }  
    }
