What are getters and setters for in Java? What’s the point of using them?
Rather than just giving access to a variable directly, you can use a method that retrieves the value (the getter), and another that alters the value (the setter). There are a couple reasons you might want to do this. The biggest one is control. If you just have a public variable, anything outside the class can do whatever it wants, even if it isn't technically "right" (like giving something a negative length, as an example). With the getter/setter methods, you can program extra logic to ensure that you have correct values (like throwing an exception if you try to use a negative length). You can also only provide a getter if you wanted, effectively making it so that the variable can only be read, not directly altered (at least outside the class). Another reason is to hide implementation details. If your class is storing time, as an example, you can have setters and getters for time in minutes, time in hours, time in seconds, etc. These getters and setters can use calculations to translate the units between minutes/hours/etc. to whatever is being used by the internal variable, rather than just sticking with one and remembering that the variable is in milliseconds or something. Alternatively, the "internal variable" can just not exist, like the getArea() method of a Rectangle class (meaning you only need to store length and width; though there are optimizations you can do by storing area too, and having the setters for length/width recalculate as needed). Another reason is logging. You can have your getters and setters record the fact that a retrieval or alteration occurred, giving you an easy way to debug (rather than having to find every single place you messed with a particular variable). Getters/setters can also be changed by inheritance, given that they are methods. And even if you aren't doing anything special right now, it is a good idea to have them in case you come back and find that you need to change the logic to use getters/setters. It is a lot easier to add special getter/setter functionality when you are already using them, as opposed to looking for every variable use. ------------------------------ Edit: TL;DR: In Java, a getter is just a method that gets some value (usually from a variable), while a setter is just a method that sets the value of a variable. They have advantages over just accessing the variable directly, since you can add additional logic as needed, like enforcing proper values, logging, etc. More on reddit.com

In Java getters and setters are completely ordinary functions. The only thing that makes them getters or setters is convention. A getter for foo is called getFoo and the setter is called setFoo. In the case of a boolean, the getter is called isFoo. They also must have a specific declaration as shown in this example of a getter and setter for 'name':
class Dummy
{
private String name;
public Dummy() {}
public Dummy(String name) {
this.name = name;
}
public String getName() {
return this.name;
}
public void setName(String name) {
this.name = name;
}
}
The reason for using getters and setters instead of making your members public is that it makes it possible to change the implementation without changing the interface. Also, many tools and toolkits that use reflection to examine objects only accept objects that have getters and setters. JavaBeans for example must have getters and setters as well as some other requirements.

u/Ellisander 's explanation is good. I want to clarify one thing, though. A lot of things in programming, like loops, are tools to help you to get the computer to do things. However, some features of programming language are the opposite: they're not there to help you make the computer do something, they're there to help you organize your program better. Programmers have found, through experience, that as programs get larger, if you make all of the variables public then it tends to lead to lots of bugs. Basically if you let any part of the program change anything at any time, it becomes difficult to manage. Not difficult for the computer! The computer literally doesn't care. It's difficult for you, and other programmers who need to read your code. Getters and setters are one tool to help manage the chaos. You don't HAVE to use them, but it's good practice for larger projects.

Adityavardhan Singh I would suggest you to take up Java because C++ is kind of semi OOP because you can run a program without having a class.
Whereas Java is fully OOP, I'm saying this because only primitive data types did not have classes but then you have wrapper classes for them.
I don't want to get into the details and since you want to get into app development, Java is one of the best languages for that.

February 29, 2024 - It plays a pivotal role in why we use getters and setters in Java. Encapsulation is a mechanism that binds together code and the data it manipulates, and keeps both safe from outside interference and misuse. In Java, encapsulation is achieved by declaring the variables of a class as private and providing public getter and setter methods to manipulate those variables.
