Checking Java Collection Generic Type for an Empty Collection

Question

I want to implement the following function:

public boolean checkType(Vector vec)
{
  // return true if its Vector and false otherwise         


        

Answer 1

public boolean checkType(Vector vec)
{
  if(!vec.isEmpty())
  {
    if("String".equals(vec.get(0).getClass().getSimpleName()))
             return false;
    else if("Integer".equals(vec.get(0).getClass().getSimpleName()))
             return true;               
   }
}

Hope this helps!!
