4414	Java - converting an integer to a fixed length string There are some things in Java which you would think are no-brainers (one-liners) but turn out to be not quite so simple. This issue has improved over the years, with additions of methods like split to java.lang.String, but some gaps remain. And the solution - the joy of an OO langauge - is for you ...	2015-02-04
4393	Splitting Java strings and extracting numbers In Java you can use packages in the utility class to handle strings, or you can use methodsin java.lang.String which has been enhanced from version to version and now includes methods such as String.split(). Examples from today's course - taking a line of data (which could have been read from a file) ...	2015-01-15
3048	String handling - from first steps to practical examples Initial String handling examples on a training course are sometimes a bit mundane - and that's because we have to cover some of the basics like "what is a string" before we start reading them in useful quantities from files, databases, or web resources. But it's important to get those basics understood ...	2010-11-13

1557	Trying out our Java examples on our web site We've included all of the source code of our training examples on this web site for quite a long time now ... and about a year ago we put working copies of most of the PHP scripts up there too (we have left out those which show security holes). Now we're in the process of adding some of the Java code ...	2008-02-28
1446	An answer to a student asking 'Help' I've got time - a lot of time - to help people who are learning; it's really rewarding to teach the subjects that we do, and the most rewarding students are those who take the time to go above and beyond the norm in asking questions. So why, when I get an email out of the blue asking for help with a ...	2007-11-27
