<DIV><FONT size=2>Hi,</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I've some puzzles from my recent learning about
OpenJDK7.0.</FONT></DIV>
<DIV><FONT size=2>Firstly, I want to know that whether I can change the java
programes' behavior via changing some source files in OpenJDK, for
examples, execute the following codes will print "100".</FONT></DIV>
<DIV><FONT size=2> int i=100;</FONT></DIV>
<DIV><FONT size=2> System.out.println(i);</FONT></DIV>
<DIV><FONT size=2>My question is that how to print "200", without changing the
source codes. Is it possible?</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Secondly, the number of files in the OpenJDK project is very
large, I want to know how these files are structured. Besides, how can I debug
the project? For examples, When I run HelloWorld, I use the command "java
HelloWorld", I want to know how the OpenJDK </FONT><FONT size=3>interpret this
command, I think the best way is reading the source codes, but I don't know
where to start.</FONT></DIV>
<DIV> </DIV>
