Why

char c = (int) 1;

doesn't result with compilation error? As I tried few combinations, compilator accepts any values from char range, even if they are int-casted. Can somebody give me formal explanation? Thnx

Even if you don't cast 1 to int still it's int.

Compiler accepts it because at the compilation time it knows that the value can fit in char variable.

char is an "unsigned short under the roof", it will accept any unsigned short:

Greetings from Hogwarts,

Bro, I got what you are asking.. but still it makes sense for the compiler not to complain...

we know that:

"char var can be assigned an int without any cast as long as it is within the char range."

so when you say char c=(int)1, you are really not saying anything different. It is totally the same as saying char c=1, becoz 1 without any cast is an int anyway.

So the compiler won't complain..since your casting is not making any difference... I think I make sense...

Gula,
I speak both polish and russian . They are indeed similar. f.e., "kurit' travku" sounds similar to "palic trawe". On the other hand, "tusovka" has nothing common with "impreza". I like Russian and if java would not exist, I would be probably a filologist.
Thanks everyone for brief explanation. I'm taking exam in 5 days - after 2 weeks learning (no time). Wish me luck!
 
It is sorta covered in the JavaRanch Style Guide.
