XOR Gate using JAVA

I am trying to code an XOR Gate and I found this:

return in[0] != in[1];

where in[0] is for example true and in[1] is false. I understand that ! gives the negation but why is = used?

Solution

  • Consider the truth table:

    0   1   XOR
0   0   0
1   0   1
0   1   1
1   1   0

    The example works because 0 is equal to false and 1 is equal to true In both cases, 0 != 0 is false = 0, since 0 does equal 0. You can work out all other
