This is an official introduction, meaning that Lombok makes Java programming simple and fast with some special handling.
#VISUAL STUDIO SHORTCUTS GETTER SETTER AND TOSTRING HOW TO#
Introduction to Lombok Project Lombok makes java a spicier language by adding 'handlers' that know how to build and compile simple, boilerplate-free, not-quite-java code. So when we create POJO classes, we don't hesitate to let the developer generate set, get methods for domain variables.Although we don't add them manually (shortcut keys or menus are generated quickly), it's also annoying to have repetitive generations for each class.And when the variable name or modifier changes, we delete the set, get method, and regenerate, which is a repetitive and tedious operation.Lombok is one of those artifacts that we can use to increase productivity and avoid repetitive operations. There are two ways to manipulate these domain variables.The first is through a public-style constructor, or constructor, that assigns values to the variable as soon as the object is instantiated.The second is to assign and value variables through set and get methods.In this way, the security of domain variables can be improved and the encapsulation of domain variables can be guaranteed.( You would need to use the boundary checking logic everywhere that accesses it (then handle any errors if the checks fail), rather than preventing invalid data input altogether.There are closeness and security features in Java object-oriented programming.Closure is the enclosure of domain variables in a class, that is, decorate them with private s.As a result, other classes cannot access the variable.In this way, we enclose these variables within the class, which improves the security of the data. It should never be accessed by your class's internal methods if it requires boundaries as to what state it should be in or requires a particular range. It is always public, and never checked when altered.

This now lets the calling code handle acceleration and braking, updating the Car object when it wants to.īut you still have the overall control of what that value can be, rather than controlling how it is changed.Īs Merriam demonstrated is all well and good if you don't care when, and to what value, external code will set this property. Here is another example but the external code can set the value immediately: public class Car This lets the calling code call to increase speed, or slow down holding the brake, as many times as they want.īut you can now put a realistic limit on that speed - the user cannot break the rules you have in you application's 'world'. Lets go with speed of a car: public class Car

You want that value to be changed - but under your control.Ī bank balance perhaps? Or the speed of a car?

You have a class that is created with a known value. If you just want a 'Name' to be instantly changeable and it has no bearing on the application when it is, the above public string Name is all you will need.īut if you are tracking/using/controlling the value of a property within your class and you don't want external code changing it, then the second example is the one to go with. However, it will depend on what you are wanting external code to be able to access. This uses an internal private variable that is used when the property is accessed.

Shorter and easier to read would be something similar to: public class Carrots
