List를 Json으로 변환

1. Gson Download

Gson is a Java library that can be used to convert Java Objects into their JSON representation. It can also be used to convert a JSON string to an equivalent Java object. Gson can work with arbitrary Java objects including pre-existing objects that you do not have source-code of.

• Gradle

dependencies {
    implementation 'com.google.code.gson:gson:2.8.5'
}

• Maven

<dependency>
    <groupId>com.google.code.gson</groupId>
    <artifactId>gson</artifactId>
    <version>2.8.5</version>
</dependency>

2. Sample Code

public static void main(String[] args) {

    List<String> foo = new ArrayList<String>();
    foo.add("A");
    foo.add("B");
    foo.add("C");

    String json = new Gson().toJson(foo);
    System.out.println(json);
}
