When we need to execute a set of statements based on a condition then we need to usecontrol flow statements. For example, if a number is greater than zero then we want to print “Positive Number” but if it is less than zero then we want to print “Negative Number”. In this case ...
>> check out the course 1. overview decision constructs are a vital part of any programming language. but we land up in coding a huge number of nested if statements which make our code more complex and difficult to maintain. in this tutorial, we’ll walk through the various ways of repla...
Performance— Provides performance that is comparable to, if not better than, existing APIs such as JNI and sun.misc.Unsafe. Generality— Provides ways to operate on different kinds of foreign memory (e.g., native memory, persistent memory, and managed heap memory) and, over time, to accommo...

(We could also include braces on just one of the two bodies.) double max; if(first > second) max = first; else max = second; I recommend that you include the braces anyway. This saves you trouble later, should you decide to add additional statements into the body of the statement. ...
The JMS API provides no mechanism for browsing a topic. Messages usually disappear from a topic as soon as they appear: if there are no message consumers to consume them, the JMS provider removes them. Although durable subscriptions allow messages to remain on a topic while the message consumer...
