Should you always use getters?
Using getters and setters, is always, in my opinion good practice. One thing you should avoid is to have external entities mess with the internal structure of your class at will. Typical example, consider having a dateOfBirth parameter.
Is it possible to use constructor as getters?
3) Constructor is invoked implicitly. Method is invoked explicitly. 4) Getters(), or accessors, are methods that provide access to an object’s instance variables.
Are setters and getters constructors?
The constructors are used to initialize the instance variable of a class or, create objects. The setter/getter methods are used to assign/change and retrieve values of the instance variables of a class.
How can I get the all getter methods of a?
Usually you don’t want properties from Object.class, so you’d use the method with two parameters: BTW: there are frameworks that do that for you and present you a high-level view. E.g. commons/beanutils has the method ( docs here) which does just that: find and execute all the getters and store the result in a map.
How to use @ builder on a method?
I want to use @Builder on some sort of factory method since I can’t make any changes to the implementation. Can someone give an example on how to actually use @Builder on a method?

How to create a builder class in Java?
Java Builder class should have methods to set the optional parameters and it should return the same Builder object after setting the optional attribute. The final step is to provide a build () method in the builder class that will return the Object needed by client program.
Which is an example of the Builder pattern?
Here is the sample builder pattern example code where we have a Computer class and ComputerBuilder class to build it. Notice that Computer class has only getter methods and no public constructor. So the only way to get a Computer object is through the ComputerBuilder class.
