Given this, getters and setters are also known as accessors and mutators, respectively.īy convention, getters start with the word "get" and setters with the word "set", followed by a variable name. The get method returns the value of the variable name. The following examples show that when you assign a value to the property, the set accessor is called using an argument that provides the new value and when you assign the property value to another variable, the get accessor is called to read the value of the property. 00:16 Attributes hold the internal state of objects. In JUnit, you can pass the parameters into the unit test method via the following methods : 1. These attributes are just variables that you can access through the instance, the class, or both. Click on the Run example button to see how it works. Usually, class fields are decorated with a private access specifier. When you define a class in object-oriented programming, you’ll likely end up with some instance and class attributes. Example 2: Getter and Setter methods for maintaining the value within the range In this example, we have a class named SetGet where we are looking at whether the number is in a given range or not. Getter and setter methods in Java are widely used to access and manipulate the values of class fields. For example, a setter method might be used to ensure that a person’s age is set to a valid value between 0 and 120. Getters and setters are used to protect your data, particularly when creating classes.įor each instance variable, a getter method returns its value while a setter method sets or updates its value.
