Can not change the default encoding for InputStreamReader

Name: tb29552 Date: 06/15/99


I change the default encoding :

java -Dfile.encoding=Big5 myclass

But it has no effect on InputStreamReader()
For example,

System.out.println(System.getProperty("file.encoding"));
InputStreamReader in=new InputStreamReader(System.in);
System.out.println(in.getEncoding());

It prints out:

Big5
MS950

my version is:
java version "1.2"
HotSpot VM (1.0fcs, mixed mode, build E)
