So, in this article, I will try to highlight the importance of the lombok project and cover in-depth every point related to Data annotation. Using lombok Data can surely provide significant technical benefits to our Java projects. It reduces the required extra code that usually brings no real value to the business side of our applications. In short, Data is a special annotation provided by the lombok project. Its main purpose is to automatically generate all the extra code that is frequently associated with POJOs and Java beans. You may wonder what is boilerplate code. Well, it is the repetitive code that we have to write each time such as:. The lombok project comes with a host of ready-to-use annotations. However Data is very special because it provides an implicit shortcut that binds together all the following annotations:. Please bear in mind that each annotation has one specific purpose, we should use it only when it makes sense. For example, we use the ToString annotation only when we want to implement the toString method. Lombok hooks itself into the compilation phase and acts as an annotation processor that generates the extra code we need for our classes. To work with lombok plugin, we need to configure it first. Follow the below steps to add it in eclipse Windows OS :. Go to the jar file location, then execute it or run this command line in your terminal: java -jar lombok. Once the Lombok window is opened, specify the eclipse. If you are a big fan of Maven like me, you need just to add the following dependency in the pom. For instance, consider the Person class:. As we can see, we have already more than lines of code for a class with 5 properties. Person class has just 5 properties, so it is normally a basic simple Java class. However, with the extra code of the getters and setters … we ended up with a quite overwhelming boilerplate zero-value code. You may say that most Java IDE can also auto-generate getters and setters and even more for us with just a few clicks. Yes, you are right. However, the generated code needs to live in your sources and must be maintainable and maintained. With this annotation, we will be able to focus only on what is important in our class: its data and its representation. Cool, right? The code is more clearer and concise that way. As shown above, there is less code to write and maintain. Lombok does not stop here, it can provide more flexibility and readability to our code. Please keep in mind that Data annotation is like having the following implicit annotations:. With some adjustments added to our previous example, we can end up with a class that can only be instantiated through a static factory method. With the help of the staticConstructor attribute, we can tell Data to generate a private constructor and a public static factory method:. That way, we can create our instances using Person. Please keep in mind that we can also use the old naming conventions such as newInstance. The best thing about the data annotation is its flexibility as it can be used alongside other annotations. For example, we can use Data with Setter AccessLevel. NONE to make our class read-only. We can use it also with AllArgsConstructor to generate an all-args constructor instead of the default required args constructor. By default, Data includes all the fields when generating getters, setters, and other implementations. Though all hope is not lost, we can combine Data with other lombok specific annotations to address our central question:. As shown above, we can use the Exclude parameter to ignore and skip the annotated fields. As we have already mentioned in the beginning, Data generates a required-args constructor. However, this behavior will change if we add Builder to the equation. Using Data and Builder annotations together will generate an all-args constructor instead. The problem here is that most DI Frameworks such as Spring rely on a no-args constructor to initialize objects. So, a nice workaround to fix this issue would be using the NoArgsConstructor annotation to generate the default constructor for us. The big difference between Value and Data annotation is that Value is mainly used to create immutable objects. As we can see Value , unlike the Data annotation, does not contain Setter annotation. Omitting setters is the first step for promoting immutability. In this article, we explained in detail what is lombok Data annotation and how we can use it in our Java projects. Along the way, we have showcased how to use it with Builder and explained the core difference between it and the Value annotation. I hope you have found this article helpful, enlightening and inspiring to convince you to give lombok a chance to get into your Java development toolset.

Avoiding Java Boilerplate Code with Project Lombok

Why I choose Lombok to spend my 4 month of winter is simple: I love warm climates. I visited Lombok from start December till end of March. Nature on Lombok is stunning. If you avoid the main roads you will see green all around you. It varies from large ricefields to beautiful forests. There is a fair amount of waterfalls all around the main item on the island: Mt Rinjani. You can visit them all with the help of a guide. If you absolutely want to visit the crater lake you have to come after April and before January. My visit was in the rainy season. As you may expect, that is the period where rain may fall. You can see it coming over Rinjani. Main roads are good to very good. It actually is amazing to find this quality of road on the island. But, as soon as you leave the main road you may find every quality that you may think of, varying from dirt road to roads with bigger and smaller holes. Traffic on all roads is terrible. Expect to be overtaken by somebody who is overtaken by somebody who is overtaken by ……. Lines on roads have no meaning, they are crossed by anybody who wants to be faster than the other person. There is quiet some honking done by the fast drivers. With my rented bicycle a transported myself many kilometers on the beautiful island. To be able to stay on Lombok actually Indonesia you need a visa. The one you can get on arrival is only valid for 1 month. You can also first visit an embassy abroad and get one there. In that way I bought a visa for 60 days and had two extensions of 1 month each. Extending a visa is not really difficult, nevertheless I had it done by an agent for kRp each. Google about visa extension, there are lots of articles you can find, even how to do yourself, which cost only kRp. Shopping can be done in different levels. There are hundreds of small shops that sell you whatever you want. If you want imported goods you have to visit the supermarkets that are also in abundance in the villages. Small shops sell cheap stuff, supermarkets take their price for the imported goods. If you want cheese or yoghurt, count on paying double or more. Do visit Epicentrum and Mataram Mall in Mataram. You will find a contact to the group by searching on Facebook. As they have various start points for their activities you may try to get a ride from one of the participaters. For connecting to the Internet you can buy an Indonesian sim-card. Prices are very reasonable. For 20GbGb you will pay between kRpkRp. The quality of the connection is varying. Speed is good enough to watch a movie if you can accept the occasional lag. Do not drink water directly from the tap. Not even the local people will do so. At many places hostels and homestays you can fill up your bottle for free. In my 4 month I only had a minor diarree event, a friend, staying one month, had a weeklong minor bacterial infection that was cured by medicines. They are easily found, just ask the local people. A simple treatment may cure you easily. The cause of these 2 minor disease cases was food. I was in doubt already by the semi-dirty hands of the guy preparing my coconut, the infection probably had to do with hygiene. You cannot always avoid it, just be prepared for the serious stuff by taking the vaccines that your health organisation suggests you to take. Mosquito is annoying. Not more than annoying, there are not so many, never heard of malaria in those 4 month. Another story is noseeums. If you are sensitive for these bastards, take care. For me it meant closing the door and window after sundown and living inside with ventilator or dressing with long sleeves and trousers when outside. They are way more annoying than mosquitos. The value for European visitors is easiest calculated like: All together Lombok is a beautiful island and absolutely worth a visit if you want to escape the more touristic experience of Bali. By using Google, Instagram, Pinterest etc you will find loads of info about what to do and experience. Have fun, I did ;. Toggle Navigation. Lombok My Trip. Travelling in Lombok can be done in many ways. Install the BlueBird app or wait by the side of the road. Driver with car who transports you for an agreed price which may be a little lower than a taxi. Go-Jek is a scooter driver system where you sit on the buddy seat. Install the GoJek app or wait by the side of the road. Walking is only an option for very short distances, unless you are a very sporty person and used to the heat. I have stayed in different places in Lombok. They are nice though, with large swimming pools and close to the beach. I used homestays which were booked via AirBnB and booking. Since I was here in rainy season, there were many rooms vacant. In high season you will probably not be able to do so. Homestays have different levels, most are very nice with good rooms and beds, western toilet and proper shower. Lombok is called the island of a thousand mosques. And that is correct as far as I can see. Some mosques are standing less than m apart. The first homestay I lived in was right opposite a mosque. And, as I experienced, you can sometimes hear prayer calling from different mosque at the same time. I did not get used to that in those 4 month. What also struck me was the state the mosques are in. All beautifully built and painted, in the middle of poor slumlike huts that the people live in. Why this inequality? All around Lombok you will find beaches. But by far the best beaches are in the south. From Kuta you can visit some of them when you rent a scooter. They are pure white dusty sand, they all have small warung where you can buy some food and drinks and all are very good for surfing. Most beaches are suitable for snorkeling. You may find many small fish and a lot of unfortunately mostly dead coral. You can also book a boat for a x-island tour. They know where to go and may have equipment for rent to you. You will enjoy the quietness as motorized traffic is forbidden on all of them. Horse carriages will bring you anywhere or you can rent a bicycle. Alcohol is relatively expensive. Large beer is 40kRp, wine I never bought, simply too expensive. Data is my internet connection that I had by using an Indonesian sim-card Shopping. Now I do haha, In the Epicenter, in the shop Matahari, you can buy fairly cheap. Div means mostly that I forgot what I used the money for : Excursion is trips we made with driver and or guide Rent is all the expenses I had for renting room. You can do cheaper, I always had my own room with shower and toilet. Dormitory are cheaper Visa is the price I paid for my 2 extensions. Base visa was 2 mmonth, extension per month. Exact location.
