• You can store objects of any class in an ArrayList.
• Usually, the objects you store in an ArrayList will all be of the same class: this is called a homogeneous list.
• However, occasionally you will want a mix.
• So let us add a Date object to this ArrayList:

  0165:       Date tDate = new Date();
  0166:       tList.add(tDate);
  

• You can do this because add has a parameter of type Object.
