Weird java behavior with casts to primitive types

Why following prints 1?

int i = (char) - (int) + (long) - 1;
System.out.println(i);

Why above lines of code prints 1? How come the value of i become 1?

Answer 1

If I am not mistaken,

int i = (char) - (int) + (long) - 1;

is actually equivalent to

int i = (char)(-(int)(+((long)(- 1))));

since -1 and 1 fit nicely into all data types used in the expression, we can drop the casts to get

int i = -(+(- 1));
