How to fill out use of array variables

How to fill out use of array variables:

1. Start by declaring the array variable using the appropriate data type. For example, if you want to create an array of integers, you would declare it as "int[] arrayName".
2. Determine the size of the array by specifying the number of elements it can hold. This can be done either during the declaration or later using the "new" keyword. For example, "int[] arrayName = new int[5]" creates an integer array that can hold 5 elements.
3. Initialize the array by assigning values to each element. This can be done using a loop, manually specifying the values, or by copying values from another array. For example, you can use a for loop to assign values to the array elements: "for(int i = 0; i < arrayName.length; i++) { arrayName[i] = i+1; }".
4. Access and manipulate the elements of the array using their index. The index starts from 0, so to access the first element, you would use "arrayName[0]". You can also use loops to iterate over the array and perform operations on each element.
5. Finally, make sure to handle any errors or exceptions that may occur when working with array variables.
