public class Z{
public static void main(String [] args){
new Z();
}

Z(){
Z z1 = this;
Z z2 = this;
System.out.println("begin !");
synchronized (z1){
try{
z2.wait();
System.out.println("done waiting !");
}catch(InterruptedException e){
System.out.println("interrupted !");
}catch(Exception e){
System.out.println("other exception !");
}finally{
System.out.println("finally !");
}
}
System.out.println("all done !");
}
}
请分析可能出现的结果，并分析原因：一道面试题目
