Construct the name of the method to be called at runtime

I'm learning Java and I'm fairly new to this. Here is my problem with some pseudocode:

public void objectCaller(int objectNumber) {

   switch(objectnumber) {

     case 1:
     object1.setFill(color.RED);
     break:

     case 2:
     object2.setFill(color.RED);
     break;
     .
     .and so on

    }
}

Is there a way to replace it in a way with something like that?

public void objectCaller(int objectNumber) {

   (object + objectnumber).setFill(color.RED);

}

It is not a concrete problem. I was just thinking about if it is possible to assemble the object names.
