Java反射构建方法含有参数列表

public class ReflectserviceImpl {
    private String name;
    public ReflectserviceImpl(String name){
        this.name=name;
    }
    public void sayHello(){
        System.out.println("Hello  "+name);
    }



public Object reflect(){
    ReflectserviceImpl reflectservice=null;
    try {
        reflectservice= (ReflectserviceImpl) Class.forName("ReflectserviceImpl").getConstructor(String.class).newInstance("呼呼");
        System.out.println(reflectservice);
    } catch (Exception e) {
        e.printStackTrace();
    }
    return reflectservice;
}
