- Array objects, like other objects, are created with new. For example, String[] arrayOfStrings = new String[10];declares a variable whose type is an array of strings, and initializes it to hold a reference to an array object with room for ten references to strings.
- Another way to initialize array variables is
String[] arrayOfStrings = { "array",
"of",
"String" };
Widget[] arrayOfWidgets = { new Widget(), new Widget() };
- Once an array object is created, it never changes length! int[][] arrayOfArrayOfInt = {{ 1, 2 }, { 3, 4 }};
- The array's length is available as a final instance variable length. For example,
System.out.println(arrayOf1To5.length);
would print "5".
