That is possible. Can you show what you have so far? This can be done easily in processing java first and then run it in Android mode.

```auto
int x = 100;
int y = 100;
int sz = 100;

int x1 = 300;
int y1 = 100;

color bgcolor;
PShape rectangle;
PShape Ellipse;

void setup() {
  rectangle = createShape(RECT,x1-50,y1+80,sz,sz);
  Ellipse = createShape(ELLIPSE,x1,y1,sz,sz);
  size(400, 300);
  colorMode(HSB);
  noStroke();
  smooth();
  
  fill(random(255), 100, 200);

  background(color(255, 150, 255));
}
void draw() {
  background(color(255, 150, 255));
  
  if(dist(x,y, mouseX, mouseY) < sz / 2) {
   
    if(mousePressed) {
      x = mouseX;
      y = mouseY;
      if(x==x1&&y==y1){ stroke(0);strokeWeight(7);};//check if on the same coordinates
      if(x!=x1&&y!=y1){ noStroke();};
    }
    
  } 
  shape(Ellipse);
  shape(rectangle);
  ellipse(x, y, sz, sz);
 
}

```

what needs to be modified by the code is:  
after moving the left circle to the right one I want to drop it there and forget about it.  
secondly

is there is a way to find the match other than coordinates comparison.?

thanks in advance.
