### Question:
EPoint extends Point2D implements Serializable { @Override public double getX() { return getLambdaX(); } EPoint(double lambdaX, double lambdaY); private  EPoint(long gridX, long gridY); static EPoint fromLambda(double lambdaX, double lambdaY); static EPoint fromGrid(long gridX, long gridY); static EPoint snap(Point2D p); @Override double getX(); @Override double getY(); double getLambdaX(); double getLambdaY(); long getGridX(); long getGridY(); @Override void setLocation(double x, double y); Point2D.Double lambdaMutable(); Point2D.Double gridMutable(); double lambdaDistance(EPoint pt); double gridDistance(EPoint pt); boolean isSmall(); boolean equals(EPoint that); String toString(); static void printStatistics(); static final EPoint ORIGIN; }### Answer:
@Test public void testGetX() { System.out.println("getX"); assertEquals(10 / DBMath.GRID, p0.getX(), 0); }
