In a new four-part series of articles, beginning with this one, I'll continue where I left off one year ago and show you how to make the most of Java's Metadata. In this first article I'll explain the purpose of
If AutoCommit is enabled for the Connection object, the IBM Data Server Driver for JDBC and SQLJ adds a commit method at the end of the batch. If the PreparedStatement object returns automatically generated keys, call DB2PreparedStatement.getDBGeneratedKeys to retrieve an array of ResultSet object...
In Go, a method is a function that executes in the context of a type. A method set, on the other hand, is the collection of all the methods with a receiver of a particular type. The method set determines the interfaces that the type can implement and how the methods can be called. ...
Notice how the owners() parameter takes a simple string as a default value while the type of the parameter is *array* of Strings. That's possible thanks to varargs, another J2SE 5.0 feature. (For more information about varargs and also the new enum facility used to define the Priority ...
Java Decision Making - Explore Java decision-making concepts including if, else, and switch statements to control program flow efficiently.
The --dockerfile option makes it possible to build a new minified image directly from source Dockerfile. Pass the Dockerfile name as the value for this flag and pass the build context directory or URL instead of the docker image name as the last parameter for the build command: slim build...
find_all elements in an array that match a condition? I've an array of hash entries, and want to filter based on a paramater passed into the function. If there are three values in the hash, A, B, and C, I want to do something similar to: find all where A... ...

That’s why we can use property observers on an array (as in the example above in the Container class) to notify us of changes. What’s actually happening, is that a new array is created with the changes; it is assigned to the property, and then didSet gets invoked. Thus, if you ...
The first accepts an array and, using Java's new foreach loop, calls dump() on each item in the array. The second accepts a single item and performs the bulk of the work. The workhorse dump() method first checks if the Unfinished annotation is present. If not, there's nothing to ...
