Core Java Programming Course- Array Object

The video tutorial explains how to declare an integer array with a fixed size, highlighting that all elements are initialized to default values, which is zero for integers. It demonstrates using a loop to display these default values and shows how to update specific elements in the array. The tutorial also covers creating arrays of different data types, emphasizing that the size of an array is fixed upon declaration and cannot be changed later.

What happens to the elements of an array that are not explicitly initialized?

Can the size of an array be changed after its declaration? Explain your answer.
