如何重写doubles的compareTo方法？

public class MyDouble implements Comparable<MyDouble> {
    private double value;

    public MyDouble(double value) {
        this.value = value;
    }

    public double getValue() {
        return value;
    }

    public void setValue(double value) {
        this.value = value;
    }

    @Override
    public int compareTo(MyDouble other) {
        if (this.value < other.value) {
            return -1;
        } else if (this.value > other.value) {
            return 1;
        } else {
            return 0;
        }
    }
}

MyDouble double1 = new MyDouble(3.14);
MyDouble double2 = new MyDouble(2.71);

int result = double1.compareTo(double2);
if (result < 0) {
    System.out.println("double1小于double2");
} else if (result > 0) {
    System.out.println("double1大于double2");
} else {
    System.out.println("double1等于double2");
}
