Get/Set Values for Static Fields and Properties

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

Custom JAR library

With Javonet you can easily get or set a value for any static field or property from a class or structure from JAR library by calling the "get(fieldOrPropertyName)" or "set(fieldOrPropertyName, newValue)" method on reference to .NET/Java type. Conversely, foreign instance types can be stored in Java variables using the dedicated Java type called NType.

As with the methods, value-typed results are automatically translated into Java types and reference results are returned as NObject\JObject objects.

Assuming we have a custom JAR library with the following class inside:

import java.util.*;
import java.lang.*;

public class TestClass {
    public TestClass() { }

        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;
            }
        }
        
}
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;
    }
}
