//1 System.out.print((-x == ~x + 1)+","+(-y == ~y + 1));
}}

Actually the highest precedence operators -,~ are evaluated first
so ~3 is -4, and ~5 is -6.
Then next highest priority operator + is evaluated,
so lefthand value will be -3 which is equal to right hand operand.
The result will be true,true.

so ~3 is -4, and ~5 is -6.
