Appending to a String 1

[Enea]

I have the following:
StringBuffer s=new StringBuffer();
s.append("add this");

If I want to attach "ing" to the word add, meaning I want to have s="adding this" how do I append in between characters?

Use the insert(int offset, String str) method of StringBuffer.

Are you using the Java API Docs? If you are serious about using Java, then you CANNOT make progress without them. They would have alerted you to the presence of this method, for instance.

I am studying Java and using Eclipse.
When I enter the object name followed by a dot, I can see all the methods available to me. Is that what you meant?

Thank you for your reply. I tried it and it works.

By Java API Docs, I mean the J2SE 1.4.2 Documentation, available at

http://java.sun.com/j2se/1.4.2/download.html

... or the J2SE 5.0 Documentation available at

http://java.sun.com/javase/downloads/index.jsp

With these, you will learn vastly more about what's available in Java than relying on the code completion features of the IDE you're using.

Thanks Tim. I am not relying on code completion to learn the language; I have a couple of good books.
But thank you for the link you sent me.
