Question

I am looking for a Java API which allows to write and read the property files in the following format:

<prefix>.<index>.<suffix>=<value>

For example:

launcher.1.id=23
launcher.1.name=abc
launcher.1.date=123123
launcher.2.id=sdfsdf
launcher.2.name=Asdfdsf
launcher.2.date=ghfgh
cec.1.id=sdfsdf
cec.1.name=Asdfdsf
cec.1.date=ghfgh
cec.2.id=sdfsdf
cec.2.name=Asdfdsf
cec.2.date=ghfgh
#...

log4j uses very similar format for configuring the appenders:

log4j.rootLogger=debug, stdout, R
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p 
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=example.log
log4j.appender.R.MaxFileSize=100KB
log4j.appender.R.MaxBackupIndex=1
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n

Anybody has an idea if there is a Java library for a case like this?

Thanks,
Ilya

The correct solution was to reconsider the format and use JSON for this. Thank you @ControlAltDel for the idea.
