Remove the last line from the 'explode' method. Each bomb should be able to decide for itself when to explode. You probably already have a timer so when the elapsed time has expired, it will explode. If you have an Explosion class, detecting a neighbouring explosion could be a trigger to explode as well.

we wrote it so that the play has to activate the bomb with the e key 
public void act() 
    {
      if(Greenfoot.isKeyDown("e"))
      {
        explode();

        
      }
so that all bombs are exploding at the same time but when i delete the last line the Bomb stay on the map an dont disappear !

That I was not aware of. Sorry (add that line back in if you have not already). But because each will be removing itself when exploding, that line should read: getWorld().removeObject(this); Move the code in the act method just provided to the world class and have the world class call explode on all bombs in the world. 
// in world act method (or a method it calls)
if (Greenfoot.isKeyDown("e")) for (Object obj : getObjects(Bomb.class)) ((Bomb) obj).explode();

java.lang.IllegalStateException: Actor not in world. An attempt was made to use the actor's location while it is not in the world. Either it has not yet been inserted, or it has been removed. at greenfoot.Actor.failIfNotInWorld(Actor.java:663) at greenfoot.Actor.getNeighbours(Actor.java:829) at Bomb.explode(Bomb.java:25) at Schlachtfeld.act(Schlachtfeld.java:13) at greenfoot.core.Simulation.actWorld(Simulation.java:571) at greenfoot.core.Simulation.runOneLoop(Simulation.java:506) at greenfoot.core.Simulation.runContent(Simulation.java:213) at greenfoot.core.Simulation.run(Simulation.java:203) This is the message i get when i copied in the world class actor. The bombs both going away but the result explode is only by the first i set in the world. I hope you understand what i mean lg

If you did not do this step, that error will occur.

When you changed it to what I suggested (which is what is should be), what error message are you getting (copy/paste the whole error message to your post).

method removeObjects in class greenfoot.World annot be applied to given types; required java util collections found: Bomb reason:actual argument Bomb cannot be converted to java.util.collection by method invocation conversion The Operator that you use here cannot be used for the type of veluethat are you are using it for You are either using thhe wrong type here or the wrong operator

Please show your world class code for the 'act' method (and, if you are calling a method from there to check for exploding bomb trigger, that method, as well).

NVM, you did not remove the 's' to turn 'removeObjects' into 'removeObject'.
