  2. Array of java • Topics: 1. What is Array? 2. Array variables 3. Pass by reference 4. Multidimensional Arrays

  3. What is an array? • An array is a very common type of data structure wherein all elements must be of the same data type. • Once defined, the size of an array is fixed and cannot increase to accommodate more elements. • The first element of an array starts with index zero. • Ex; x[0]=0; x[1]=1; x[2]=2; x[3]=3; x[4]=4; x[5]=5;

  4. ARRAY VARIABLES • Using an array in your program is a 3 step process - 1) Declaring your Array 2) Constructing your Array 3) Initialize your Array • 1) Declaring your Array Syntax: <elementType>[] <arrayName>;

  5. Contd…. • 2) Constructing an Array Syntax: arrayname = new dataType[] • 3) Initialize an Array Syntax: intArray[0]=1; // Assigns an integer value 1 to the first element 0 of the array intArray[1]=2; // Assigns an integer value 2 to the second element 1 of the array

  6. PASS BY REFERENCE • Arrays are passed to functions by reference, or as a pointer to the original. This means anything you do to the Array inside the function affects the original.

  7. MULTI DIMENSIONAL ARRAY • Multidimensional arrays are actually arrays of arrays. • To declare a multidimensional array variable, specify each additional index using another set of square brackets. • Ex: inttwoD[ ][ ] = new int[4][5] ; • When you allocate memory for a multidimensional array, you need only specify the memory for the first (leftmost) dimension. • You can allocate the remaining dimensions separately.
