            Edit: code updated to use org.json.

            Below is a working implementation that handles your example.

            The function that actually does the work is match, which recursively traverses the filter and applies each node to the supplied object. The function returns true if the given object satisfies the given filter.

            Conceptually the match function is mapping each construct in your filter language (AND, OR, EQ, LT etc) into its Java equivalent. E.g. AND maps to Stream.allMatch, NOT maps to the Java ! operator, EQ maps to Object.equals, etc. I.e. match is defining the semantics for your filter language.

            I hope the code is self-explanatory - let me know if anything is unclear.

            Does it matter if function returns T or object if T can not be inferred from context?
            Asked 2020-Nov-17 at 23:41

            I found the following source code in gson:



            Answered 2020-Nov-17 at 23:41

            This doesn't return Object but a type that's either inferred from the context or – if that's not possible – by passing a type parameter with a type witness: YourClass.fromJson()

            Note that this won't magically work. If the object that's returned from the internal call isn't compatible with T at runtime, the assignment (of the outer return value) will throw a ClassCastException.

            How to import json array into java program using JSON.ORG
            Asked 2020-Oct-15 at 07:52

            I am learning to work with json files and I'm using the JSON-java library from https://github.com/stleary/JSON-java

            1. I was able to manipulate data for this json dataset

            You are almost there, all you have to do is to new a JSON array from jsonToken as follows:

            BTW, I think the JSON library you are using is org.json, not JSON.ORG. And both of your JSON strings are invalid, if no other JSON object exists behind comma, please remove it.

            org.json cannot be resolved to a module?
            Asked 2020-Oct-12 at 03:53

            I'm learning Java. To read JSON in my application, I downloaded this JSON library; which is an automatic module.

            I included that library in my module descriptor like:



            Answered 2020-Oct-11 at 23:00

            TL;DR — As this unresolved 'Cannot be resolved' errors in projects with module-info.java issue reports, vscode is brain dead when it comes to JPMS and module-info.java.

            The long-winded version

            From my own experience, I can personally vouch for what the reporter of the above-linked vscode issue reports…

            …I've tried both Gradle and Maven…

            …I find that Gradle and Maven will automatically refresh the classpath file and remove my modifications to it, which will bring back the errors…

            …there needs to be module path information set in the classpath file in order for Eclipse to be happy, but there is no good way to do with that from Gradle or Maven…

            Proof that it's a vscode issue is that the exact same project — unchanged except for the removal of your comment — compiles perfectly fine in IntelliJ…

            Since your project uses neither Maven nor Gradle — opting instead to use file-based dependency mgt with the jar in the lib folder — you're in even worse shape because you've eliminated the option of applying any JPMS-enabling plugins that could resolve the issue.

            For example, by adding the following pom.xml with the appropriate configuration for the maven-compiler-plugin to my experimental version of your project…

            I'd just flatten it first (first console log), unless you want the whole "outer" array, in which case just do .find twice:

            I have a legacy application which has been built with java 1.5, I need a conversion between byte[] and json but I cannot use jackson or gson, because they are in a higher version of java. I have methods like these and I couldn't find a way to implement with JSONObject :

            If it would be so easy, then Jackson or Gson was never be born.

            I am affraid, that you have to declared deserializer for all of your objects manualy. This is not a rocket science, but it takes time to do it. This is an example:

            Convert Excel to JSON - using React-Dropzone (client side probably)
            Asked 2020-Aug-20 at 19:12

            This is similar to question: Excel to JSON javascript code?, but using React and Dropzone.

            I either need to upload the Excel file to the server and parse it there, or parse it in the browser to JSON, then upload the JSON.

            I have written React (frontend) and Server side (backend) to process a CSV file and store to MongoDB. The React side is below.

            My two issues have been:

            1. If I do it on the client side, how to use XSLX or sheetjs to read and process a file dropped using DropZone

            2. If I do it on the server, how to properly upload the Excel file (I've read posts about setting Mime-Extension for Office/Excel). I've been able to upload a file, but I can never open it in Excel after it has been uploaded. It's usually double the size, probably UTF-8 to UTF-16 conversion happening.



            Answered 2020-Aug-20 at 19:12

            Got XLSX working on the client based on this post: Parse XLSX with Node and create json.

            In other words, the browser side converts the Excel to JSON, and posts the JSOn to the server. I'm assuming there will just be one worksheet, and convert the first one only if there are more than one.

            I'm not entirely sure why he need both types of readAsBinaryString and readAsArrayBuffer, but it's working fine.

            Proposed Fix…

            1. System.out.println( new Json( ).toJson( new JSONContainer<>( ... ) ) to see the correct string format of a JSONContainer's JSON.
            2. Make sure your result input argument to Json.fromJson(Class, String) is in the same format printed out in 1.
              • e.g. {myObject:{class:CommonNoun,cid:{oid:139},name:Jada Pinkett Smith,form:69},children:[{myObject:{class:CommonNoun,cid:{oid:666},name:Jaden Pinkett Smith,form:-666},children:[]},{myObject:{class:CommonNoun,cid:{oid:69},name:Willow Pinkett Smith,form:69},children:[]}]}

            JsonObject vs JSONObject
            Asked 2020-Jul-30 at 13:40

            I am a bit confused about Json Class in java libraries. I could find these 3 at least and all seems Oracle Json Libraries

            Why so many Oracle json class?



            Answered 2020-Jul-29 at 15:58

            You are mixing up a lot of things here.

            javax.json is part of the JSON-B and JSON-P Java EE API - used for JSON processing and data binding. And used in context of an application server (WildFly / Tomcat / ...)

            whereas com.oracle.json refers to Java ME ("Micro Edition").

            and org.json is just another parser, like GSON.

            You wouldn't use com.oracle.json outside of a Java ME environment, but whether you use javax.json, org.json, GSON, Jackson, ... is up to your personal taste and requirements. But mostly, the application server already contains a JSON parser - for Wildfly, this was Jackson until JSON-B/P arrived rather late to the parsing party.
