If you have Apache `commons-lang` as a dependency already then [`WordUtils`](http://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/text/WordUtils.html) can do this. — andyb, Mar 13 '13 at 11:30

You could try this:

String d = "DRIVER";
d = d.substring(0,1) + d.substring(1).toLowerCase();

Edit:

see also StringUtils.capitalize(), like so:

d = StringUtils.capitalize(d.toLowerCase());

Actually `d.substring(0,1).toUpperCase() + d.substring(1).toLowerCase()`, but the trick is clear. – Javier Mar 13 '13 at 11:29

String str = "DRIVER";
String strFirst = str.substring(0,1);
str = strFirst + str.substring(1).toLowerCase();

public static void main(String[] args) {
    String txt = "DRIVER";
    txt = txt.substring(0,1).toUpperCase() + txt.substring(1).toLowerCase();            
    System.out.print(txt);
}

I would use CapitalizeFully()

String s = "DRIVER";
WordUtils.capitalizeFully(s);

s would hold "Driver"

capitalize() only changes the first character to a capital, it doesn't touch the others.

I understand CapitalizeFully() changes the first char to a capitol and the other to a lower case.

https://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/text/WordUtils.html#capitalizeFully(java.lang.String)

By the way there are lots of other great functions in the Apache Commons Lang Library.

I am using Springs so I can do:

String d = "DRIVER";
d = StringUtils.capitalize(d.toLowerCase());

Rather than post your own answer which just duplicates one of the existing answers, you should accept one of them. – ChrisF Mar 13 '13 at 16:01
