compiler-errors - 在我的Triangle类中找不到符号错误

由于某些原因，我不断收到Triangle.is_equilateral，Triangle.is_isosceles和Triangle.is_scalene的找不到符号错误。

这是Triangle类:

public class Triangle
{
    private int s1;
    private int s2;
    private int s3;

    public Triangle (int num1, int num2, int num3)
{
        s1= num1;
        s2= num2;
        s3= num3;
}

    public String toString()
    {
    return (s1 + " " + s2 + " " + s3);
    }

    public boolean is_equilateral(){
if(s1==s2 && s2==s3 && s3==s1)
    {
    return Triangle.is_equilateral;
    }
else
{
    return false;
}
}

    public boolean is_isosceles(){
if((s1==s2)||(s2==s3)||(s3==s1))
{
    return Triangle.is_isosceles;
}
else
{
    return false;
}
}

    public boolean is_scalene(){
if(s1!=s2 && s2!=s3 && s3!=s1)
{
    return Triangle.is_scalene;
}
else
{
    return false;
}
}


    }

这是测试程序:

 public static void main (String[] args) {

      Scanner console = new Scanner(System.in);
      int num1;
      int num2;
      int num3;
      String another;
      do
      {
         System.out.println("Enter the sides of the triangle: ");
         num1 = console.nextInt();
         num2 = console.nextInt();
         num3 = console.nextInt();

         Triangle myTriangle = new Triangle (num1, num2, num3);


        System.out.println(myTriangle.toString() + " triangle:");

        //check the isosceles
        if (myTriangle.is_isosceles())
           System.out.println("\tIt is isosceles");
        else
           System.out.println("\tIt is not isosceles");

        //check the equilateral
        if (myTriangle.is_equilateral())
           System.out.println("\tIt is equilateral");
        else
           System.out.println("\tIt is not a equilateral");

        //check the scalene
        if (myTriangle.is_scalene())
           System.out.println("\tIt is scalene");
        else
           System.out.println("\tIt is not scalene");


        System.out.println();
        System.out.print("Check another Triangle (y/n)? ");
        another = console.next();

    } while (another.equalsIgnoreCase("y"));


   }  // method main

}  // class Assignment5

谢谢你的帮助。非常感谢。

最佳答案

您尚未在类is_equilateral中声明成员is_isosceles，is_scalene和Triangle您需要添加它们:private bool is_equilateral;private bool is_isosceles;private bool is_scalene;
