Dear all,
I tried to read a large number of files into an ArrayList with the
following code:
var file_list:ArrayList[String]=new ArrayList[String]();
for( f1 in (0..1000)){
for(f2 in (0..30)){
val f_name=f1.toString()+"_"+f2.toString();
val file=new File(f_name);
if(file.exists()) {
//Console.OUT.println(f1+"_"+f2);
for(s in file.lines()){
file_list.add(s);
}
}
}
}
But in the implementations I always meet the error:
Uncaught exception at place 0: x10.lang.MultipleExceptions
x10.io.FileNotFoundException: 50_22

Actually the file 50_22 exists. I tried to initialized the size of the
arraylist with a number large enough, and close the filereader after
reading each file as well, but still meet the same error. Is there any
comment about this?
Thanks,
Long
