An array of strings
String[] cars = {"Volvo", "BMW", "Ford", "Mazda"};
An array of integers
int[] myNum = {10, 20, 30, 40};
Change an Array Element
String[] cars = {"Volvo", "BMW", "Ford", "Mazda"};
cars[0] = "Opel";
System.out.println(cars[0]);
// Now outputs Opel instead of Volvo
Array Length
String[] cars = {"Volvo", "BMW", "Ford", "Mazda"};
System.out.println(cars.length);
// Outputs 4
Multidimensional Arrays
int[][] myNumbers = { {1, 2, 3, 4}, {5, 6, 7} };
Access Elements
int[][] myNumbers = { {1, 2, 3, 4}, {5, 6, 7} }; System.out.println(myNumbers[1][2]); // Outputs 7
Change Element Values
int[][] myNumbers = { {1, 2, 3, 4}, {5, 6, 7} }; myNumbers[1][2] = 9; System.out.println(myNumbers[1][2]); // Outputs 9 instead of 7
