How to Initialize an Array in Java ?

Answer

To initialize an array in Java, you can use array literals or the new keyword.

✐ Examples

1 Initialize Array using Array Literals

In this example,

We initialize an array named numbers using array literals with integer values.
This creates an array of integers in Java.
We print the array elements to the console.

Java Program

public class Main {
    public static void main(String[] args) {
        int[] numbers = {1, 2, 3, 4, 5};
        for (int number : numbers) {
            System.out.print(number + " ");
        }
    }
}

Output

1 2 3 4 5

2 Initialize Array using new Keyword

In this example,

We initialize an array named fruits using the new keyword with string values.
This creates an array of strings in Java.
We print the array elements to the console.

Java Program

public class Main {
    public static void main(String[] args) {
        String[] fruits = new String[] {"Apple", "Banana", "Orange"};
        for (String fruit : fruits) {
            System.out.print(fruit + " ");
        }
    }
}

Output

Apple Banana Orange
