What is Getter and Setter in Android

Question

What is getter and setter in android development.

And what is the use of @Expose in GSON.

@SerializedName("url")
    @Expose
    private String url;

same thing as in `java`. Please make sure you pass basic `java` training before you continue to Android. — Vladyslav Matviienko, Sep 02 '19 at 20:22

Getter = accessing variable to be able to use

Setter = assigning a new value to variable

@Expose is used to decide whether a variable will be exposed for serialization/deserialization or not

In Java, getter and setter are two conventional methods that are used for retrieving and updating value of a variable.

Something like:

public class Example {
    private int number;

    public int getNumber() {
        return this.number;
    }

    public void setNumber(int number) {
        this.number = number;
    }
}

@Expose is an annotation. The official doc:

An annotation that indicates this member should be exposed for JSON serialization or deserialization.
