Answer 1

You can add the objects to a list and then print them all.

This is very simple, hope it can help you some.

public void print(List<Object> objectList)
{
  for(Object obj : objectList)
  {
      System.out.println(obj);
  }
}

Another way you can implement it by using variable parameter

code sample is as follows:

public void print1(Object ... objectList)
{
  for(Object obj: objectList)
  {
      System.out.println(obj);
  }
}

Using variable parameters, you can print objects like follows:

    Test t = new Test();
    Object o1 = new Object();
    Object o2 = new Object();
    Object o3 = new Object();
    t.print1(o1);
    t.print1(o1,o2);
    t.print1(o1,o2,o3
