Pulling the most recent file by file name?
# see "perldoc -f sort" # sort numerically @sorted = sort {$a <=> $b} @data; # sort numerically and return greatest: $greatest = (sort {$a <=> $b} @data)[-1]; # or $greatest = (sort {$b <=> $a} @data)[0]; -
Finding a previous line
while (<>) { if (/^A/) { # print remebered lines of one of them contain 12345 foreach (@temp) { print; } if (grep /12345/, @temp); # clear temp @temp = (); } else { push @temp, $_; } } -
Two-dimensional array/While statement not exiting - very strange
Another - more perlish - way is: foreach (@aliasdata) { print TEMP $_->[1]; } This make no use of temporary variables. -
formatting a file.

How do I make an .exe file from my java programs?

j2ee
It merely all the same question: Accessing a EJB which may run in an external (non-local) Container. Generally you will have to lookup the bean via JNDI and a full url. For JBoss as an example EJB Container a full url would be "jnp://otherserver/application/beanB" You have two... -

The class name ist java.util.Calender not java.util.calender Java classnames (and other identifiers) are case sensitive! -
Newbie - Class / Array question
Declaring an array of a type does not create the actual instances in the array's "slots". You have to create the instances by yourself: Class MyClass { ... } ... myClass[] = new myClass[3]; // Create the _array_ instance. myClass[0] = new myClass(); // Create the MyClass... -
JList Problem
This depends on your model. If youre using DefaultListModel and you are putting Strings inside then customerList.getSelectedValue().toString() will work for you. If you have a custom model, say customerModel which has a method getCustomer(int id) you would use the following to extract the... -
