2. Drag-n-drop Gson .jar into your Eclipse project source folder

3. Right click on jar - add "Build path" -> "Add to build path"

4. Source code

package com.codingtrabla.demos;

import java.util.ArrayList;
import java.util.List;

import com.google.gson.Gson;

public class GsonUsageDemo {

public static void main(String[] args) {

Gson gson = new Gson();

List<String> list = new ArrayList<String>();

list.add("New York");
list.add("London");
list.add("Sydney");

String json = gson.toJson( list );

System.out.println(json);

}

}

Output:
