Arrays in Java - Single & Multidimensional

Java Arrays

Arrays are used to store multiple values in a single variable, instead of declaring separate variables for each value.

String[] cars = {"Volvo", "BMW", "Ford", "Mazda"};
int[] myNum = {10, 20, 30, 40};

Access Elements

Access elements by index (starts from 0).

System.out.println(cars[0]); // Outputs Volvo

Change Element

cars[0] = "Opel";

Array Length

System.out.println(cars.length);
