Hi
I have a simple HelloWorld.java file which prints data to screen.
When compiled to a .class file the size is 469 bytes. When the same
file when compiled to an object file, the size is 1420 bytes. The
difference is much bigger if there are lots of java files. Can anyone
please explain why there is such a big difference between the two
sizes and is there a way to reduce the size of the compiled object
file ?

Java bytecode is very compact. You can see why by reading the Java VM
specification.

Sometimes strip can help.
