Hello everyone, I am new to Processing and have just been starting to play with it in the past couple of weeks. I am working on some small exercise to make myself familiar with I/O and bumped into a problem that I couldn't figure out.

I am creating a sketch that loads coordinate data (a pair of x, y) from a txt file. And then I want to save the coordinates into an object I defined. The problem is, when I tried to create a class with overloaded constructor, the problem always tells me the constructor is not defined. Anyone's help would be highly appreciated.

Below are the pde source file and the text file.

[load_text_file.pde]
-----------------------------------------------------------
Point[] points = new Point[5];

String[] s = loadStrings("points.txt");
for(int i=0; i<s.length; i++) {
 println(s[i]);
 points[i] = new Point(s[i]);
}

class Point {
 float _x;
 float _y;
 
 Point(float tempx, float tempy) {
   _x = tempx;
   _y = tempy;
 }
 
 Point(String tempPoints) {
   String[] coordinate = split(tempPoints, ',');
   _x = float(coordinate[0]);
   _y = float(coordinate[1]);
 }
}
------------------------------------------------------------

[points.txt]
------------------------------------------------------------
100,50
25,70
60,60
------------------------------------------------------------

The error message is:
The constructor Point(String) is undefined.



Thanks!

Thank you very much for your help, NoahBuddy. I added in the 'setup' method and the problem is solved.
