Converting a file to JsonObject with GSON

GSONFileTest.java

import com.google.gson.JsonElement;
import com.google.gson.JsonObject;
import com.google.gson.JsonParser;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;

public class GSONFileTest {

public static void main(String[] args)
{
   convertFileToJSON ("/tmp/test.json");
}

public static JsonObject convertFileToJSON (String fileName){

        // Read from File to String
        JsonObject jsonObject = new JsonObject();
        
        try {
            JsonParser parser = new JsonParser();
            JsonElement jsonElement = parser.parse(new FileReader(fileName));
            jsonObject = jsonElement.getAsJsonObject();
        } catch (FileNotFoundException e) {
           
        } catch (IOException ioe){
        
        }
        
        
        return jsonObject;
    }

}

    JsonElement jsonElement = JsonParser.parseReader(new FileReader(file));
    JsonObject jsonObject = jsonElement.getAsJsonObject();

Now-a-days the best method on how to do this is by

JsonParser.parseString(Files.readString(path)).getAsJsonObject()

Extremely simple.
