How to display class's not inherited methods and fields

I would like to display on the console only methods of the class which were not inherited. If I wanted to display all of them I would just use:object.getClass().getMethods(); but then I would get all of the method declared in the class and I would like to get only those which are genuinly declared in the class I am analyzing.

The Method class has a getDeclaringClass() method which returns the class in which the method is declared. You can use it like so

public class Driver {
    public static void main(String[] args) {
        Method[] methods = Driver.class.getMethods();
        for (Method method : methods) {
            if (method.getDeclaringClass().equals(Driver.class)) {
                System.out.println(method);
            }           
        }
    }

    public void doSomething() {
    }
}

In other words, you check if the method is declared in the actual type you are interested in.

Or use what Marko suggested.

There is a method just for what you need: getDeclaredMethods(). It returns all declared methods, as opposed to getMethods(), which returns all public methods, whether inherited or not.
