Question

For various reasons I am trying to set a string to 2000 spaces. Currently I am using:

String s = String.format("%1$-2000s"," ");

This is great for Java 5, however, some of the developers in our department are using 1.4 and this does not work.

I was wondering, are any other ways of achieving the same result? I know I can do things like a for loop adding a space at a time, but I am looking for something simple like the format option.

For those that may be interested in why I need this, it is because we have an XML type on a dataobject that on insert into the DB is null. It then gets updated with the XML string, usually around 2000 characters in size. In Oracle pre-reserving this space can prevent row migration, therefore, increasing performance.

Thanks!

Answer 1

char[] spacesArray = new char[2000];
Arrays.fill(spacesArray, ' ');
String spaces = new String(spacesArray);
