Cobol is a structured language where as Java is a High level
and Object oriented Language. Cobol has extensive facilities
for report generation.

Answer / vish

What I believe is that COBOL was actually the prime
business language and used extensively for mainframes batch
systems (although it is used recently in UNIX servers too
which are in most cases migrated from mainframe system to
UNIX systems). At present we have more powerful languages
available than COBOL which can of course provide more value
add for a system development. But still COBOL continues to
be the primary development language for mainframe systems,
some of the reasons could be:
1. Almost all the existing big legacy systems were
developed using COBOL. Now converting these systems to
other languages is a very costly business.
2. Most of the legacy systems using COBOL are batch systems
(although they have online components using mostly CICS)
and COBOL well serve the very purpose efficiently.

Any comments/suggestions are welcome!!!

Answer / kprasad

Few differences I can list down as following
1)Originally and still mostly Cobol is structured prog
langualge. Offcour se there are now a days OOD concepts in
cobol also. Bust still baasically it is structured prog.
lang. On the other hand Object Orientation is the base of
Java.
2) Cobol is developed for and still used for Business
Processing. You can have your business processing modules,
DB interaction modules in cobol. I haven't heard cobol used
for any system level prog or web developement or UIs. But
Java can be used along all layers of application from
presentation to business layers. Also now a days Sun has
developed JMV using Java itself.
3) Cobol compilers are platform dependent I suppose. Java
is platform independent.
4) Cobol is a lunguage as such but looking at the current
developmet Java has become more than a lunguage, a platform.
5) Cobol is not providing not many built in functions,
libraries like java

input 1 input2 ouput1 output2 output 3 1 re 300 1 re 200 1 re 300 3 rc 500 1 re 200 2 rr 400 1 re 300 2 rr 400 1 rc 400 3 rc 500 1 rc 400 2 rr 700 2 rr 700 5 tt 900 5 tt 900 2 inputs r in flat file and output 1 is matched records,ouptput2 is unmatched of input1,output3 is unmatched of input2! how vl u get the output files using sequential order and to check with each and every records! let me know the procedure division ?
