Java:可以调用未知参数的函数

Question

从理论上讲，如果“sensorFinal”类无法访问整数“value”，“sensorFinal”类中的函数“absSensor”如何能够调用“proximitySensor”类中的函数“proximitySensorAdjusted” “？

是否有标准方法来调用对数据的访问受到限制的函数，或者是否有解决方法？提前致谢!

public class proximitySensor
{
    double adjustment = 5;
    public double proximitySensorAdjusted(int value)
    {
        double finalValue = value + adjustment;
        return finalValue; 
    }
}

public class sensorFinal
{
    public double absSensor()
    {
        proximitySensor sensorValue = new proximitySensor();
        sensorValue.proximitySensorAdjusted( ??? ) 
    }
}

Answer 1

您可以使用方法重载。

public double proximitySensorAdjusted(int value) {
    double finalValue;
    if(value == -1) {
        finalValue = adjustment;
    } else {
        finalValue = value + adjustment;
    }
    return finalValue;
}

public double proximitySensorAdjusted() {
    return proximitySensorAdjusted(-1); //call with some default value
}

现在您可以调用sensorValue.proximitySensorAdjusted();。
