    Question Help with logical operators

    hi everyone I am having trouble getting my logical operators to work correctly, I believe I am making an error somewhere that I cannot find myself. I created a method called "type" where I am trying to determine the type of triangle by comparing side 1, side 2, and side 3. which i shortened to s1, s2 and s3. It seems that even when I enter all three sides the same, it still claims that it is an Isosceles Triangle when it should say that it is a Equilateral Triangle. Any help would be appreciated, thanks.

    public static void type(double s1, double s2, double s3){
     
                if(s1 == s2 || s1 == s3 || s2 == s3){
                    System.out.println("The triangle is Isosceles since it has two equal length sides.");
                }
                else if(s1 == s2 && s1 == s3 && s2 == s3){
                     System.out.println("The triangle is Equilateral since it has equal length on all three sides.");
                }
                     else {
                     System.out.println("The triangle is Scalene with no equal sides.");
                }
            }

    Switch your Isosceles and Equilateral if loops. With the code as it is right now, If the triangle is an Equilateral, the first if loop will find at least 2 sides equal and return true, and you will get the Isosceles message. Check for Equilateral before the Isosceles check.
