Best way to replace a special word in java

In my current project, I have requirement to replace a word with a value in a paragraph.

Ex :

"Event name is {[Event].[Name]} Contact name is {[Contact].[Name]}"

In the above line, '{[Event].[Name]}' should be replaced by the event name. The first part is an object (event). There are different objects. The second part (name) is a property of the object.

I have the Objects and relevant property values with me.

Can someone please tell me the best way to do this?

Should I use regex, a for loop or something else?

Something like this? 

String.format("Event name is %s. Contact name is ‰s", event.getName(), contact.getName()) ;

If you need something more complex than that, use Velocity or FreeMarker templates

Something like this should for for replacing it, but there is better ways to define the regex expression

String str = "Event name is {[Event].[Name]}";

String eventStr = "event";

String nameStr = "name";

str = str.replaceAll(Pattern.quote("{[Event].[Name]}"), String.format("%s.%s", eventStr, nameStr));

a simple String replace (or two)

str = str.replace ("{[Event].", value1).replace ("[Name]}", value2);

Not sure if you wanted the . replaced or not
