### Question:
Coord implements Localizable { @Override public String toString() { return new StringBuilder(MIN_LENGHT).append(getClass().getSimpleName()) .append(" [x=") .append(x) .append(", y=") .append(y) .append("]") .toString(); } 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 testToString() { assertEquals("Coord [x=1.5, y=2.5]", new Coord(1.5, 2.5).toString()); }
