Java Language -- Types: Array
Arrays are "true" or "first class" objects in Java and no pointer arithmetic is supported.
Like other objects, an array must be declared and created:
- int states[]; // declaration
- alternative syntax: int[] vec;
- and then:
- states = new int[128]; // creation
- or concisely:
- int states[] = new int[128];
Arrays of arbitrary objects can be constructed,
- e.g. Color manycolors[] = new Color[1024];
- The only difference is that in the case of primitive types, the array elements are actually created. In the case of arbitrary objects, an array of object references is created; before you use array elements, you must call the constructor of that type for each element.
