Check textures overlapping

Question

Hey i am writing a game when there are bunch of textures that changes locations, but i want to check that they are not drawing over other textures, i tried to write a code for checking it but its not working well.

Here is the code i tried:

circles.setPosition(new Vector2(r.nextInt(width-height/8*2)+height/8,
                                r.nextInt(height-height/8*2)+height/8),
                                i);

circl[i].set((float) (circles.getPosition(i).x+height/16),
             (float) (circles.getPosition(i).y+height/16),
              height/16);

    while(isLaping = true){

        System.out.println("in");

        for(int y = 0; y < circlesArray.length-1; y++){

            if(Intersector.overlaps(circl[y], circl[y+1])){

                circles.setPosition(new Vector2(r.nextInt(width-height/8*2)+height/8,
                                                r.nextInt(height-height/8*2)+height/8),
                                                i);

                circl[i].set((float) (circles.getPosition(i).x+height/16),
                             (float) (circles.getPosition(i).y+height/16),
                              height/16);
            }else{
                isLaping = false;
            }
        }
    }

How to fix it?

I think you are, at it's core, trying to check the collision for circles. If that is the case, http://stackoverflow.com/a/1736741/2586284 or http://stackoverflow.com/a/8566438/2586284 should answer your question. — Sierox, Dec 20 '14 at 14:56
I know how to check the collision i dont know how to check if it touches one of the circles and if not to draw it. — user3419789, Dec 20 '14 at 15:19

this is confusing,

while(isLaping = true){

you mean it

while(isLaping == true){

or

while(isLaping){

while(isLaping=true); isLaping never is false at the moment evaluate while because asign true every time

This does not provide an answer to the question. To critique or request clarification from an author, leave a comment below their post. – djv Dec 20 '14 at 19:46
@Verdoline I do not intend to criticize the author, simply emphasize if this is what you want or a simple mistake, if an error can your code does not work as desired and that's the solution, while(isLaping=true); isLaping never is false at the moment evaluate while because asign true every time – Angel Angel Dec 20 '14 at 19:57
You can put that comment right in the "answer" to make it more of an answer than a critique / question. – djv Dec 20 '14 at 19:58
@Verdolino did not think to put it that way, they could be interpreted as a critique of the author, thanks – Angel Angel Dec 20 '14 at 20:02

I tried again to do so with your tip but the circle are getting crazy and changes places every second

this is the code i have been trying.

            for(int i = 0;i<circlesArray.length;i++)
        {
            if(circlesArray[i]>200)
            {
                changePosition(i);

            }
            circlesArray[i]++;
        }


    private void changePosition(int i)
{
    int s = 0;
    circles.setPosition(new Vector2(r.nextInt(width-height/12*2)+height/8,r.nextInt(height-height/12*2)+height/12),i);
    circl[i].set((float) (circles.getPosition(i).x+height/24),(float) (circles.getPosition(i).y+height/24),height/24);

    while (lap == true)
    {
    circles.setPosition(new Vector2(r.nextInt(width-height/12*2)+height/8,r.nextInt(height-height/12*2)+height/12),i);
    circl[i].set((float) (circles.getPosition(i).x+height/24),(float) (circles.getPosition(i).y+height/24),height/24);
    for(int y= i+1;y<circlesArray.length;y++)
    {
        if(circl[i].overlaps(circl[y]))
        {
            circles.setPosition(new Vector2(r.nextInt(width-height/12*2)+height/8,r.nextInt(height-height/12*2)+height/12),i);
            circl[i].set((float) (circles.getPosition(i).x+height/24),(float) (circles.getPosition(i).y+height/24),height/24);
            s=0;
        }
        else
        {
            s++;
        }
    }
    if(s == circlesArray.length)
        lap = false;
    }
    circlesArray[i] = 0;
    x[i] = r.nextInt(circleTexture.length);
    }
