In Java, it is common to use set and get methods to set and retrieve the values of an object’s properties.

The “set” method is used to assign a value to an object’s property, typically following the naming convention of “setPropertyName,” for example:

public void setName(String name) {
    this.name = name;
}

The get method is used to retrieve the value of an object’s property, usually named following the convention of get + property name, such as:

public String getName() {
    return this.name;
}

Using the set method allows you to set the value of an object’s attribute, while the get method allows you to retrieve the value of an object’s attribute. This ensures that the object’s attribute values are not directly accessed or modified from outside, improving encapsulation and security.
