My program is being used to find what type of triangle my values represent. There are issues with the if-else statement regarding types (Java) [duplicate]

This question already has an answer here:

• incomparable types: boolean and double 5 answers
• Is there clean syntax for checking if multiple variables all have the same value? 12 answers

I'll get straight to the point. In the first if-statement I get an error regarding the types. I have commented below on where the issue occurs. How can I fix this?

public class Tutorial3 {
public static void main(String[] args) {
int a = 50;
int b = 50;
int c = 50;

if (b == a == c){  //This if statement says "incomparable types boolean and int"
    System.out.println("This is a Equilateral Triangle");
}
else if (c == a || c == b || b == a ) {
    System.out.println("This is a Isosceles Triangle"); 
}
else if (c != a || c != b || b != a) {
    System.out.println("This is a Scalene Triangle"); 
}
}
}
