Question

public class Picture
{

    private Square s1;
    private Square s2;
    private Square s3;
    private Square s4;
    private Square s5;
    private Square s6;
    private Square s7;
    private Square s8;
    private Square s9;


    /**
     * Constructor for objects of class Picture
     */
    public Picture()
    {
        // nothing to do... instance variables are automatically set to null
    }

    /**
     * Draw this picture.
     */
    public void draw()
    {
      s1 = new Square(23,87,104,"red",true);
      s2 = new Square(23,112,104,"yellow",true);
      s3 = new Square(23,137,104,"magenta",true);
      s4 = new Square(23,87,129,"blue",true);
      s5 = new Square(23,112,129,"green",true);
      s6 = new Square(23,137,129,"yellow",true);
      s7 = new Square(23,87,154,"magenta",true);
      s8 = new Square(23,112,154,"red",true);
      s9 = new Square(23,137,154,"blue",true);
    }

}

我不得不为类创建一个rubix多维数据集，似乎无法使其工作。我一直收到错误：

cannot find symbol - constructor Square(int,int,int,java.lang.String,boolean)

有谁看到我错在哪里？请帮忙

Answer 1

您尚未包含Square的来源，但我可以告诉您，它没有包含这些参数的公共构造函数。这些行引起了问题：

s1 = new Square(23,87,104,"red",true); // etc

你的Square类需要有这样的构造函数：

public class Square {
    public Square(int a, int b, int c, String color, boolean flag) {
    }
}

找不到符号 - 构造函数（java）
