Arrays

When we declare an array variable, the code creates a variable that can hold the reference to an array object. It does not create the array object or allocate space for array elements. It is illegal to specify the size of an array during declaration. The square brackets may appear as part of the type at the beginning of the declaration or as part of the array identifier:

int[] i; // array of int
byte b[]; // array of byte
Object[] o, // array of Object
short s[][]; // array of arrays of short
