What are native methods in Java and where should they be used?

Question

Can anyone help me what are native methods in Java and where we can implement this?

Answer 1

Native methods helps you to call a complied dynamically loaded library with an arbitrary assembly code from Java and then getting the result back to Java. This will also helps us to write the faster code on a critical section. You can take a below code as a reference:

public class Main {

    public native int intMethod(int i);

    public static void main(String[] args) {

        System.loadLibrary("Main");

        System.out.println(new Main().intMethod(2));

    }

}

I hope this will help.
