调用构造器不使用反射提供的参数

public class ConstructorTrouble {
    private ConstructorTrouble(int i) {
    }

    public static void main(String... args) {
        try {
            Class<?> c = Class.forName("ConstructorTrouble");
            Object o = c.newInstance(); // InstantiationException

            // production code should handle these exceptions more gracefully
        } catch (ClassNotFoundException x) {
            x.printStackTrace();
        } catch (InstantiationException x) {
            x.printStackTrace();
        } catch (IllegalAccessException x) {
            x.printStackTrace();
        }
    }
}
