反射，变长参数的构造函数

[code="java"]
import java.lang.reflect.Constructor;
import java.lang.reflect.InvocationTargetException;

public class Hello {
private Integer h;

public Hello(int... _t) {
    int _h = 0;
    for (int i : _t) {
        _h += i;
    }
    h = new Integer(_h);
}

public void say() {
    System.out.println("Hello World! " + h);
}

public static void main(String[] args) {
    try {
        Class<?> clazz = Class.forName("Hello");
        Constructor<Hello> c = (Constructor<Hello>) clazz.getConstructor(_________);
        Hello h = (Hello)c.newInstance(3,4,5);
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    } catch (SecurityException e) {
        e.printStackTrace();
    } catch (NoSuchMethodException e) {
        e.printStackTrace();
    } catch (IllegalArgumentException e) {
        e.printStackTrace();
    } catch (InstantiationException e) {
        e.printStackTrace();
    } catch (IllegalAccessException e) {
        e.printStackTrace();
    } catch (InvocationTargetException e) {
        e.printStackTrace();
    }
}

}
[/code]

Constructor c = (Constructor) clazz.getConstructor(_________);
这个地方怎么写？

这个要变一下才行

[code="java"]
int [] a = new int[] {3,4,5};
try {
Class<?> clazz = Class.forName("Hello");
Constructor c = (Constructor) clazz.getConstructor(int[].class);
Hello h = (Hello)c.newInstance(a);
h.say();
} catch
.......
[/code]
