Creating instance and calling instance methods

You are browsing legacy Javonet 1.5 (Java<>.NET bridge for Windows) documentation. Use the left side menu or click here to switch to latest Javonet 2.0 documentation. Javonet 2.0 allows you to use any module from JVM, CLR, Netcore, Python, Ruby, Perl, NodeJS on Windows, Linux and MacOs from any application created in Java, Clojure, Groovy, Kotlin, C#, F#, J#, VB.NET, Python, Perl, Ruby, JavaScript, TypeScript, C++ and GoLang

Javonet lets you create instances of any type from JAR library. Assuming we have a custom JAR library with the following class inside

public class TestClass {
    public TestClass() {
    }

    public static int MyStaticField;

    public int MyInstanceField;

    public static String SayHello(String name) {
        return "Hello " + name;
    }

    public static int MethodExpectingPrimitiveInt(int arg) {
        return arg * 2;
    }

    public static int MethodExpectingClassInteger(Integer arg) {
        return arg * 2;
    }

    public int MultiplyByTwo(Integer arg) {
        return arg * 2;
    }

    public <T> T MyGenericMethod(T arg1)
    {
        return arg1;
    }
}

To create instance and invoke instance method from this class:

I code in:
// Todo: activate Javonet
// add reference to library
Javonet.AddReference(resourcesDirectory + @"\TestClass.jar");

// create Java object
JObject sampleObject = Javonet.New("TestClass");

// invoke instance method
int response = sampleObject.Invoke<int>("MultiplyByTwo", 50);

// write result to console
Console.WriteLine(response);

Javonet calls are very similar to regular .NET or Java calls, with a little bit of reflection style. Value-type results are automatically converted into JAR library types so you can safely assign them to JAR library variables. Reference-type results must be assigned to NObject\JObject variable.

Any calls to .NET or Java objects using Javonet can be shortened and simplified using Javonet Fluent interface.
