How to edit template documents (form letters) from files using Java?

This is my first time playing Java. I need to be able to replace some words in the template Sample template –

"Dear put_their_name_here,

I'm contacting you bla bla bla

to greet,

PUT_ COMPANY_ NAME_ HERE”

What is the easiest way (preferably using the standard library) to make a copy of this template file, add the correct words in the correct location, and then save it to the file system? I have to do a lot of such simple templates, so an easy to copy way will be good

I also use rhino to access Java through JavaScript. I'm not sure if it's different

to greet,

Chris

Solution

You are looking for Java text. messageformat：

Here are some usage examples (from Javadoc):

Object[] arguments = {
     new Integer(7),new Date(System.currentTimeMillis()),"a disturbance in the Force"
 };

 String result = messageformat.format(
     "At {1,time} on {1,date},there was {2} on planet {0,number,integer}.",arguments);

 output: At 12:30 PM on Jul 3,2053,there was a disturbance
           in the Force on planet 7.
