所以我正在研究一個三角形類，我想使用 Point2D.Double 來存儲高精度的點。import java.awt.geom.Point2D.Double;public class Triangle {private Double pointOne = new Double();private Double pointTwo = new Double();private Double pointThree = new Double();private final float PERCISION = 0.009f;public Triangle(double x1, double y1, double x2, double y2, double x3, double y3){    pointOne.x = x1;    pointOne.y = y1;    pointOne.setLocation(x2, y2);    pointOne.setLocation(x3, y3);}public Double getPointOne() {    return pointOne;}public Double getPointTwo() {    return pointTwo;}public Double getPointThree() {    return pointThree;}但是，當我在 main 中測試它并輸入下面的代碼時，它會打印出坐標，但精度非常低。我嘗試使用浮點數(shù)，但它總是以相同的結(jié)果結(jié)束。    Triangle tri = new Triangle( 0.0000, 0.0000, 2.0008, 0.0000, 0.0000, 2.0000);    System.out.println("Point 1 coordinates: (" + tri.getPointOne().getX() + ", " + tri.getPointOne().getY() + ")");    System.out.println("Point 2 coordinates: (" + tri.getPointTwo().getX() + ", " + tri.getPointTwo().getY() + ")");    System.out.println("Point 3 coordinates: (" + tri.getPointThree().getX() + ", " + tri.getPointThree().getY() + ")");這是它打印出來的內(nèi)容，以備不時之需。點 1 坐標：(0.0, 2.0)點 2 坐標：(0.0, 0.0)點 3 坐標：(0.0, 0.0)理想情況下，這就是我希望它打印出來的內(nèi)容。點 1 坐標：(0.0000, 2.0008)點 2 坐標：(0.0000, 0.0000)點 3 坐標：(0.0000, 0.0000)
