Answer 1

You've tag your question with "javascript" and "java" Oo !
This is java, not javascript : totally differents ones ^^

Try to replace {x = x ;} by {this.x = x ;}
Else you attribute the value of your parameter to... your parameter :P ( due to scope )

And maybe you need too to prefix your A class by the keyword "public" ?
