### Question:
Coord implements Localizable { public void setY(double y) { this.y = y; } Coord();  Coord(double x, double y); void translate(double vx, double vy); void set(double x, double y); void setX(double x); void setY(double y); @Override double getX(); @Override double getY(); @Override int hashCode(); @Override boolean equals(Object object); @Override String toString();  }### Answer:
@Test void testSetY() { final Coord coord = new Coord(1.5, 2.5); coord.setY(20.25); assertEquals(1.5, coord.getX()); assertEquals(20.25, coord.getY()); }
