Java Getters and Setters Explained

In Java, get and set methods are commonly used to access and modify an object’s properties. These methods adhere to the JavaBean specification and can be automatically generated based on naming conventions.

For instance, if there is a class named Person with an age attribute, you can define the get and set methods as follows:

public class Person {
    private int age;

    // Getter方法
    public int getAge() {
        return age;
    }

    // Setter方法
    public void setAge(int age) {
        this.age = age;
    }
}

In the example above, the getAge method is used to retrieve the value of the age property, and the setAge method is used to set the value of the age property. By calling these methods, you can access and modify the age property value from outside the class, while still maintaining encapsulation and data security.
