Perform the following JNI call:
Copy Code code as follows:
Package JNI;
public class Jnitransobject {
Public native testjni[] Objectmethod (String text);
static {
System.loadlibrary ("Jnitransobject");
}
public static void Main (String args[]) {
Jnitransobject jnitransobject = new Jnitransobject ();
testjni[] Testjnis = Jnitransobject.objectmethod ("JNI trans Object");
for (int i = 0; i < testjnis.length; i++) {
System.out.println (Testjnis[i].gettopic ());
}
}
}
