Object [] field = new Object[6];
field[0] = "a";
field[1] = 1;
field[2] = "b";
field[3] = 2;
field[4] = "c";
field[5] = 3;
for (Object o: field)
  System.out.print(o);

    Object[] myArray = new Object[]{"a", 1, "b", 2 ,"c" , 3};

    for (Object element : myArray) {
        System.out.println(element);
    }

An array can only have a single type. You can create a new class like:

Class Foo{
   String f1;
   Integer f2;
}

Foo[] array=new Foo[10];

You might also be interested in using a map (it seems to me like you're trying to map strings to ids).

EDIT: You could also define your array of type Object but that's something i'd usually avoid.

Object[] randArray = new Object [3]; 
randArray[0] = new Integer(5);
randArray[1] = "Five";
randArray[2] = new Double(5.0);

for(Object obj : randArray) {
    System.out.println(obj.toString());
}

Is this what you're looking for?

try using Vector instead of Array.

You could create an array of type object and then when you print to the console you invoke the toString() of each element.

Object[] obj = new Object[]{"a", 1, "b", 2, "c", 3};
for (int i = 0; i < obj.length; i++)
{
    System.out.print(obj[i].toString() + " ");
}

Will yield:

a 1 b 2 c 3
