I am trying to make the method below however vect is an obje

I am trying to make the method below, however vect is an object of an immutable class and I am confused on how to write the method so that vect can be modified.

/**
   * If active is true: moves _local by vect
   * If active is false: rotate vect by 6.
   */
   public void steep() {
       if (active == true) {
vect.move(_local);
       } else {
vect.rotate(6);
       }
   }
