Question

I want to add both String and Integer type of value in ArrayList.

For example i have array list in which i want to add name of the persons and age of the corresponding person in a single arralist.

How can i accomplish this. How can i get this? Actually i am retrieving data from database and want to save all the employee names and ages in a single array list. Like multidimensional array list.

Answer 1

Create a a person class with age and name, then create an ArrayList of that type.

class Person {
  private String mName;
  private int mAge;
  public Person(int age, String name) {
     mName = name;
     mAge = age;
  }
  public String getName() {
     return mName;
  }
  etc ........
}

ArrayList<Person> arr = new ArrayList<Person>();
arr.add(new Person(10, "joe"));
