exitcodes bigger 255, possible?

if yes, handling system, bombard whatever?

consider following java way (i'm controlling java only an example, any libel good question, some-more operation systems):

public category exitcode {
    open stationary vacant main(string args[]) {
        system.exit(integer.parseint(args[0]));
    }
}

running linux bash, advantage always values reduction equal 255, e.g. (echo $? prints exit formula before executed command)

> java exitcode 2; relate $?
2

> java exitcode 128; relate $?
128

> java exitcode 255; relate $?
255

> java exitcode 256; relate $?
0

> java exitcode 65536; relate $?
0
