### Question:
Rectangle implements Area { @Override public boolean intersects(Area area) { if (area == null) { return false; } return area.getX() + area.getWidthReal() > x && area.getY() + area.getHeightReal() > y && area.getX() < x + width && area.getY() < y + height; } Rectangle();  Rectangle(double x, double y, double width, double height); void translate(double vx, double vy); void rotate(double angle); void set(double x, double y, double w, double h); double getMinX(); double getMinY(); double getMaxX(); double getMaxY(); @Override boolean intersects(Area area); @Override boolean contains(Area area); @Override boolean contains(double x, double y); @Override double getWidthReal(); @Override double getHeightReal(); @Override double getX(); @Override double getY(); @Override int getWidth(); @Override int getHeight(); @Override int hashCode(); @Override boolean equals(Object object); @Override String toString();  }### Answer:
@Test void testIntersects() { final Rectangle rectangle1 = new Rectangle(0.0, 0.0, 10.0, 10.0); final Rectangle rectangle2 = new Rectangle(1.0, 1.0, 5.0, 5.0); final Rectangle rectangle3 = new Rectangle(4.0, 1.0, 5.0, 5.0); final Rectangle rectangle4 = new Rectangle(1.0, 4.0, 5.0, 5.0); final Rectangle rectangle5 = new Rectangle(6.0, 6.0, 5.0, 5.0); assertFalse(rectangle1.intersects(null)); assertTrue(rectangle2.intersects(rectangle1)); assertTrue(rectangle2.intersects(rectangle3)); assertTrue(rectangle2.intersects(rectangle4)); assertFalse(rectangle2.intersects(rectangle5)); assertTrue(rectangle3.intersects(rectangle1)); assertTrue(rectangle3.intersects(rectangle2)); assertTrue(rectangle3.intersects(rectangle4)); assertFalse(rectangle3.intersects(rectangle5)); assertTrue(rectangle5.intersects(rectangle1)); assertFalse(rectangle5.intersects(rectangle2)); assertFalse(rectangle5.intersects(rectangle3)); assertFalse(rectangle5.intersects(rectangle4)); }
