Description

Objects are instances of classes. A class is a grouping of related methods (functions) and fields (variables and constants).

Examples

  • // Declare and construct two objects (h1, h2) from the class HLine 
    HLine h1 = new HLine(20, 2.0); 
    HLine h2 = new HLine(50, 2.5); 
     
    void setup() 
    {
      size(200, 200);
      frameRate(30);
    }
    
    void draw() { 
      background(204);
      h1.update(); 
      h2.update();  
    } 
     
    class HLine { 
      float ypos, speed; 
      HLine (float y, float s) {  
        ypos = y; 
        speed = s; 
      } 
      void update() { 
        ypos += speed; 
        if (ypos > height) { 
          ypos = 0; 
        } 
        line(0, ypos, width, ypos); 
      } 
    }
