Examples:
MethodHandle mh = MethodHandles.lookup().findVirtual( MyClass.class, "foo", MethodType.methodType(void.class, int.class)); // the argument should be an int value mh.invoke(myObj, "abc");
// the argument should be String .class VarHandle vh = MethodHandles.lookup().findVarHandle( MyClass.class, "text", int .class);
VarHandle vh = MethodHandles.lookup().findVarHandle( MyClass.class, "text", String.class); // the argument should be a String value vh.set(myObj, 42);
