It is occasionally desirable to deny a certain Permission to some ProtectionDomain, regardless of any other permissions that domain accrues. This example demonstrates just one of all the possible approaches for satisfying this kind of requirement. It introduces a "negative" permission clas...

Shifting bits left (right) is equivalent to multiplying (dividing) by 2. It's the same in base 10: if we "left-shift" 13 by 2 places, we get 1300, or 13 * (10 ** 2). And if we take 12345 and "right-shift" by 3 places and then remove the decimal part, we get 12, or Math.floor(1234...

Sometimes you'll need to execute synchronous code from within an asynchronous task. To do this, simply schedule a synchronous task from within the asynchronous block. Bukkit.getScheduler().runTaskTimerAsynchronously(VoidFlame.getPlugin(), () -> { Bukkit.getScheduler().runTask(VoidFlame.ge...

An Annotation parameter can accept multiple values if it is defined as an array. For example the standard annotation @SuppressWarnings is defined like this: public @interface SuppressWarnings { String[] value(); } The value parameter is an array of Strings. You can set multiple values by u...

The first step you need to preform is to create a NSMutableAttributedString object. The reason we create a NSMutableAttributedString instead of NSAttributedString is because it enables us to append string to it. NSString *fullStr = @"Hello World!"; NSMutableAttributedString *attString =[...

In this example we are going to implement spring-data-elasticsearch project to store POJO in elasticsearch. We will see a sample maven project which does the followings: Insert a Greeting(id, username, message) item on elasticsearch. Get All Greeting items which have been inserted. Update a Gr...

In this example we are going to see a maven based spring boot application which integrates spring-data-elasticsearch. Here, we will do the followings and see the respective code segments. Insert a Greeting(id, username, message) item on elasticsearch. Get all items from elasticsearch Update a s...
