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;
    }

}

What's the point in the GSON libraries here? It doesn't look like you use them.

Of course he does. JsonElement, JsonObject and JsonParser are all GSON classes.

Since JsonParser is deprecated, What's the new way of doing this?

@pramodya1994 Simply use JsonParser.parseReader() or JsonParser.parseString() instead

    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.
