Brilliant first part to the tutorial! Great work!

I believe when you write assertEquals, "Coder from scratch" will come as the first parameter and getting value from node tree as second. I know it does not matter but just mentioning it since i noticed that. assertEquals(expected, actual) is the convention. BTW great video :D

Great video, thank you. DeltaJSON is really useful if you are working with JSON, it does compare, merge and graft.

hi im new to all of this but this code is giving me a error.
public class Json {

private static ObjectMapper objectMapper = getDefaultObjectMapper();
private static ObjectMapper getDefaultObjectMapper() {
ObjectMapper defaultObjectMapper = new ObjectMapper();

return defaultObjectMapper;
}

public static JsonNode parse(String src) throws IOException {
return ObjectMapper.readTree(src);
}
}

Non-static method 'readTree(java.lang.String)' cannot be referenced from a static context.

any help is appreciated

I really liked the tutorial. I just wish that you would increase font size or zoom in while typing. It is very difficult to read.

You dont have to type the main method, just type main and intellij creates it for you !
