Question

嘿，我有一个问题，运行这个应用程序，编译器显示“找不到符号”，这是指方法“SET”，有人可以帮我吗？

class Trapezoide extends Cuadrilatero {
    private double p1;
    private double p2;
    private double p3;
    private double p4;

    public Trapezoide() {
    }

    public Trapezoide(double x, double y, double x1, double y1, double x2, double y2, double x3, double y3, double x4, double y4){
        super(x, y);
        setP1(x1, y1);
        setP2(x2, y2);
        setP3(x3, y3);
        setP4(x4, y4);
    }
}

Answer 1

当（Java）编译器说：“找不到符号”时，基本上意味着“我找不到你刚才输入的内容”。所以检查你的“SET”方法，它不存在。

Answer 2

p1，p2，p3，p4的setter不存在！：

class Trapezoide extends Cuadrilatero {
    private double p1;
    private double p2;
    private double p3;
    private double p4;

    public Trapezoide() {
    }

    public Trapezoide(double x, double y, double x1, double y1, double x2, double y2, double x3, double y3, double x4, double y4){
        super(x, y);
        setP1(x1, y1);
        setP2(x2, y2);
        setP3(x3, y3);
        setP4(x4, y4);
    }

    private setP1(double aX, double aY){
        p1 = do_something_with_args_aX_aY;
    }

    private setP2(double aX, double aY){
        p2 = do_something_with_args_aX_aY;
    } 

    private setP3(double aX, double aY){
        p3 = do_something_with_args_aX_aY;
    }

    private setP4(double aX, double aY){
        p4 = do_something_with_args_aX_aY;
    }
}

找不到符号，方法集
