java - Declaration of variable size dynamic array of objects in processing -


i want ask question processing. have user defined object class, point, , have 2 data members x , y both declared float. have class recognizer. need create constructor of recognizer , inside define object of point[] point0, point[] point1, etc... dynamically.

point [] point0={new point(137,139),new point(50,63),..., new point(78,5)}; point1[],point2[],...,pointn[] 

how else can add values point0 having values of corresponding x , y coordinate.

also note size of each object point1,point2,..., pointn different.

how can achieve above goal?

how using 2 dimensional array ?

point [] points0={new point(137,139),new point(50,63),new point(78,5)}; point [] points1={new point(147,139),new point(60,63),new point(79,5)}; point [] points2={new point(157,139),new point(70,63),new point(80,5)};  void setup(){   point[][] pointlists = {points0,points1,points2};   recognizer r = new recognizer(pointlists); }  class point{   float x,y;   point(float x,float y){     this.x = x;     this.y = y;   }   string tostring(){     return "point("+x+","+y+")";   } } class recognizer{   point[][] data;   recognizer(point[][] data){     this.data = data;     for(int = 0 ; < data.length; i++){       println("processing points list" + i);       for(int j = 0; j < data[i].length; j++){         println("processing point["+j+"] of list " + + " : "+data[i][j]);       }     }   } } 

and arraylist version:

import java.util.arrays;  arraylist<point> points0 = new arraylist<point>(arrays.aslist(new point[]{new point(137,139),new point(50,63),new point(78,5)})); arraylist<point> points1 = new arraylist<point>(arrays.aslist(new point[]{new point(147,139),new point(60,63),new point(79,5)})); arraylist<point> points2 = new arraylist<point>(arrays.aslist(new point[]{new point(157,139),new point(70,63),new point(80,5)}));  void setup(){   arraylist<arraylist<point>> pointlists = new arraylist<arraylist<point>>();   pointlists.add(points0);   pointlists.add(points1);   pointlists.add(points2);   recognizer r = new recognizer(pointlists); }  class point{   float x,y;   point(float x,float y){     this.x = x;     this.y = y;   }   string tostring(){     return "point("+x+","+y+")";   } } class recognizer{   arraylist<arraylist<point>> data;   recognizer(arraylist<arraylist<point>> data){     this.data = data;     for(int = 0 ; < data.size(); i++){       println("processing points list" + i);       for(int j = 0; j < data.get(i).size(); j++){//write in nicer way, many calls, might want reusable variable here         println("processing point["+j+"] of list " + + " : "+data.get(i).get(j));       }     }   } }
