### Question:
Coord implements Localizable { public void setX(double x) { this.x = x; } 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 testSetX() { final Coord coord = new Coord(1.5, 2.5); coord.setX(10.25); assertEquals(10.25, coord.getX()); assertEquals(2.5, coord.getY()); }
