Is it a right triangle? (Code help)

[TheApostle]

Hi! My task is to create a program that takes the input of three sides of a triangle and displays a message of whether or not it is a right triangle.

Here is what I have so far...
------------------------------
import java.util.Scanner;
public class triangle {

public static void main(String[] args) {

double sidea;
double sideb;
double sidec;
String answer;

Scanner in = new Scanner(System.in);
System.out.println("Enter the 3 sides of the triangle: ");

sidea = in.nextDouble();
sideb = in.nextDouble();
sidec = in.nextDouble();

//if it is a right triangle
if (((sidea * sidea) + (sideb * sideb)) == (sidec * sidec));
answer = "right triangle";
if (((sidea * sidea) + (sidec * sidec)) == (sideb * sideb));
answer = "right triangle";
if (((sidec * sidec) + (sideb * sideb)) == (sidea * sidea));
answer = "right triangle";

System.out.print(answer);


}

}

------------------------------------------------------

I need help making an else statement that says (if all that "if" statement above is NOT true, then it is NOT a right triangle)!

Thanks!!

if (A | B | C) {
   true;
}else{
   false;
}

Keeps saying that line 29 (true;) and line 31 (false;) are not statements : \

[TheApostle]

sorry those smileys were supposed to be semicolons?- Was I supposed to put that code in underneath my System.out.print?

If you get compile errors, copy FULL text of the error messages here.
I don't know where line 29 and 31 are.


The code I posted was not java. It was just to show you how to use OR with an if statement.

Norm gave you one way to solve this. Read up on how if-else works. I'd do it like this:

if (something) {
    // code
} else if (something else) {
    // code
} else {
    // code
}

Or you can set "answer" to "not a right triangle" and just change it if it is, like you do now. Or you can just a boolean. There are many ways to do this.

Ok sorry about being stupid there for a second. I understand what you posted now and I implemented it into my code.
-----------
if (answer | answer | answer) {

System.out.print(answer);
}else{

System.out.print("Not a right triangle");
-----------

Just one problem is that it is saying that it cannot apply the "OR" (|) operator to a string. (the variable "answer" is a string)

Read about conditions and booleans also.

Where you have "answer" must evaluate to either true or false.
