How to replace values in a string?

[Ajoo Bar]

Hi,

I am trying to figure out how to do this

I have these properties in my property file
For example
Message1 = My First Name is &1 and my Last Name is &2
Message2 = &1 I live in &3

&1= John
&2=Font
&3= Florida

In my java code I read these properties from file
String message1 = My First Name is &1 and my Last Name is &2

I want to replace the ampersands with &1 and &2 in the message

The above message will look like-- My First Name is John and my Last Name is Font
And if I read message2 the Message will be John lives in Florida

How do I do that?


Thanks
Ajoo

Try using the String.replaceAll() method. Refer to the Java API for details.

Well, first you ShowSomeEffort. What have you written so far, and what results are you getting?

The policy here is not to simply hand out ready-made code.

You need not to replace the string, I think you should append the string like

Message1= "My First Name is"+ &1 "and my Last Name is"+ &2

you can't replace values in a String. Strings are immutable - once they are created, they can never be changed.

HOWEVER, you can use various methods of the String class to create a NEW String that looks like what you want, using the old String as a sort of starting point...

I wouldn't do that. I would just use the MessageFormat class which is part of the standard Java API and which is designed to do exactly that.
