Arrays of Objects

Arrays can hold reference types as well as primitive types. You create such an array in much the same way you create an array with primitive types. Here's a small program, ArrayOfStringsDemo that creates an array containing three string objects then prints the strings in all lower case letters.

public class ArrayOfStringsDemo {
    public static void main(String[] args) {
        String[] anArray = { "String One", 
                             "String Two", 
                             "String Three" };

        for (String s: anArray) {
            System.out.println(s.toLowerCase());
        }
    }
}

The output from this program is

string one
string two
string three
