Go is a programming language known for its simplicity, concurrency support, and performance, used in backend systems, cloud-native applications, and microservices.
To invoke a GoLang function from Java, you need Java Development Kit (JDK), Go compiler, Java Native Interface (JNI), cgo, javac, and java.
The process involves writing a Go function, compiling it into a shared library, and using JNI to invoke it from Java.
The shared library can then be loaded by other programs. The output file contains the compiled Go code.
A Java program can be created to load the shared library and invoke the Go function.
Go structs can be mapped using JNI in Java via C-style structure. This approach requires serialization and deserialization between Go and Java.
The System.loadLibrary method loads the shared library. The native keyword is used to declare a method that is implemented in native code (in this case, Go).
The parsed data is then printed to the console, showcasing how complex data types can be passed between Go and Java.
Integrating Go and Java through shared libraries allows developers to use the strengths of both languages: Go’s performance and simplicity combined with Java’s versatility.
