How to define an array in Java?

In Java, an array can be defined as follows:

1. Initializing an array using an array initializer:

int[] numbers = {1, 2, 3, 4, 5};

1. fresh

int[] numbers = new int[5];

1. fresh

int[] numbers;
numbers = new int[5];

1. fresh

int[] numbers = new int[5];

Please note that when creating an array, its size needs to be specified, and the size of the array cannot be changed once it is created.
