Java Coffee Mug History ~ Java is a high-level programming language that has been around for a long time since its release. And now almost anyone uses it now, it’s only a small percentage of those people who know the history of the cup. Do you even know the history of it? well, in fact… the story is rather interesting as you’ll find out.
Biggest Reasons Why Java Is So Popular Amongst Programmers
Why Java Is So Popular ~ Today we’re talking about the factors that make the 20 years old programming language “Java” is still popular amongst programmers. Nowadays Java is still the most popular programming language for developing an enterprise application.
Why android use Java? ~ Java familiarity among developers and programmers has become the key to create a program a bit quicker. This applies more to google’s android mobile platform than to Apple iOS ore Microsoft Windows Phone Platform.
Advantages of Multithreading ~ These days the shortage of time has led us to a multitasking activities. Where that multitasking has been synonymous with the needs of efficiency. And that is not an exception for the programming world, a program that does a single task is just not enough anymore.
What is the multi threading programming that we used is Java, hear this.. Java is actually a multi-threaded programming language and by that Java can let us develop a multi-threaded program.
Do you know what a multi-threaded program is? well a multi-threaded program contains two or more than two parts. Which runs concurrently and each of that one part can handle different task (i.e codes that contains methods, constructors etc) at the same equal time. This can actually improves the optimal use of the available resource, if you have multiple CPUs.
Basically multi threading programming takes the idea of multi tasking. Which is “doing more than 1 activities at the same time”. Multi tasking in our terms it means when a multiple processes share a common process resource such as a CPU. Continue reading Multi Threading Programming (Java)
If there is an entity reference in a class, then you what you have is a code aggregation. Aggregation usually represents HAS-A relationship.
Consider the following situation situation.
A Worker object contains many informations such as id, name, phone number etc. It contains one more object named address, which contains its own informations such as city, state, country etc. see it as given below.
There’s a method in java that is used to “split” string into pieces, the split is based on a given regular expressions and a return char array. There are 2 type of syntax that can be used for Java Split Method, (for a fun fact java split method is available since java 1.4).
Howdy Mowdy People? Have you ever override a method by changing its return type? Well for y’all that is already a pro in Coding may know this type of overriding, but for those who is still a green horn in coding, just like me :’D maybe. This kind of method overriding is called Java Covariant Return Type, which is not available until Java5 came out.
Here ok, let me just show you a simple presentation of this Covariant Type :
