    Default new to java need help with code asap

    hi guy, this is my first post and i need help with one of my codes asap. I am trying to replace the ellipses and rect with my custom logo. I am having trouble doing that. I know it's sounds very noobish but i guess that's how u learn.
    here is the code. I am using processing to write java
       void setup()  
        { 
          size(400, 400);  
          noStroke(); 
          rectMode(CENTER);
        } 
     
        void mouseDragged()  
        {    
          interact();
        }
     
        void draw () {
        }
        //
        void interact () {
          background(51);  
          fill(255, 80, 190);
          customLogo(width-mouseX, height/2, ((height-mouseY)/2)+10, ((height-mouseY)/2)+10);
          fill(55, 80, 105);
          customLogo(mouseX, height/2, mouseY/2+10, mouseY/2+10); 
          fill(0, 80, 219); 
          customLogo(width-mouseX+random(3), height/2, ((height-mouseY)/2)+10, ((height-mouseY)/2)+10);
          fill(200, 70, 119); 
          customLogo(width-mouseX, height/5, ((height-mouseY)/5)+10, ((height-mouseY)/5)+10);
        }
        void customLogo( ) {
           int x;
           int y;
            int squareSize;
          color fillColor = color (255, 0, 0); // color of square
          color strokeColor = fillColor;
     
          rectMode(CENTER);
          fill(fillColor);
          stroke(strokeColor);
          rect(x, y, squareSize, squareSize);
          textAlign(CENTER);
          fill(255);
          text("U", x, y+10);
        } // function

    I have another assignment with i need help with here are the instructions. I have no idea how to do the connect lines
    i have to write a sketch as the user clicks on the screen, small pulses are created. When the user hits the 'd' key, the pulses are connected together by lines with the first line segment between the first and second points made, the second line segment between the second and third points made, etc. Allow the user the clear the canvas and start over by hitting the space bar. b. Rewrite so that the first connecting line has a stroke of 1, the next a stroke of 2, the third a stroke of 3, etc. c. Rewrite so that the order in which the line is drawn is reversed, i.e., the first line sgement is drawn between the last and next-to-last points, the second line segement is drawn between the next-to-last and third-from-last points, etc
    the code

    Do you have any specific questions?
    Do you get any error messages? Please copy and paste the full text here.

    You have not posted code that will compile and execute so its impossible for anyone to test your code.
