Missing return statement making triangle program

Question

public String displayType(int side1, int side2,int side3)
    {
        if(( side1+side2 > side3))

            if(( side1==side2) && (side2==side3))//tell if         


        

Answer 1

As the final logic (in your case) will always be true, you do not need the final else if

simply

return ("Scalene Triangle."); 

But what will happen if the below if false?

if(( side1+side2 > side3))

You need to return something.
