Creating a “logical exclusive or” operator in Java

I'm struggling with trying to write Java code for an exclusive or operator.

I have 1 method called leftTurn()

leftTurn(a,b,c) XOR leftTurn(a,b,d)

&

leftTurn(c,d,a) XOR leftTurn(c,d,b)

I dont know how to construct Java code for this.

The Java XOR operator is ^.

So:

leftTurn(a,b,c) ^ leftTurn(a,b,d)

Assuming leftTurn return int

leftTurn(a,b,c) ^ leftTurn(a,b,d) leftTurn(c,d,a) ^ leftTurn(c,d,b)

If ^ is a bit obscure for you, you can just use != which does the same thing for booleans.

boolean oneTurn = leftTurn(a,b,c) != leftTurn(a,b,d);

If you need bitwise XOR, you need ^
