Arrays in JAVA


An array stores a fixed-size sequential collection of elements of the same type.


// An array is a succession of values of the same type // Create an array String[] iceCreamFlavours = new String[5];

// Initialize the elements in an array iceCreamFlavours[0] = "Cherry"; iceCreamFlavours[1] = "Vanilla"; iceCreamFlavours[2] = "Chocolate"; iceCreamFlavours[3] = "Mango"; iceCreamFlavours[4] = "Pistachio";

// The index number in an array starts with 0.



//Access the elements in an array System.out.println(iceCreamFlavours[0]); // the value listed is Cherry // To get the length of an array use .length System.out.println(iceCreamFlavours.length);

// To access the elements in an array for (int i = 0; i < iceCreamFlavours.length; i++) { System.out.println("My favourite ice cream is: " + iceCreamFlavours[i]); }

// Multidimensional arrays // Create an array // The first dimension String[][] sweets = new String[3][];

// For the second dimension sweets[0] = new String[4]; sweets[1] = new String[2]; sweets[2] = new String[3];

// Populating the multidimensional array sweets[0][0] = "pie"; sweets[0][1] = "pudding"; sweets[0][2] = "tarts"; sweets[0][3] = "candies";

sweets[1][0] = "apple strudel"; sweets[1][1] = "baklava";

sweets[2][0] = "parfait"; sweets[2][1] = "caramel sauce"; sweets[2][2] = "frozen yogurt";




// To access the elements in an array for (int i = 0; i < sweets.length; i++) { for (int j = 0; j < sweets[i].length; j++) { System.out.println("I love to eat: " + sweets[i][j]); } }
