How to fill out arrays and collections

How to fill out arrays and collections?

1. First, determine the type of data you want to store in your array or collection. This could be integers, strings, objects, or any other data type.
2. Next, declare your array or collection variable and initialize it with the appropriate data structure. For example, when using Java, you can declare an array like this: int[] numbers = new int[5]; or a list like this: List names = new ArrayList<>();
3. To add elements to an array, access each index and assign a value. For example, numbers[0] = 10; numbers[1] = 20; numbers[2] = 30; and so on. Similarly, to add elements to a collection, use the provided methods such as add(), insert(), or put(). For example, names.add("John"); names.add("Jane"); names.add("Alice");
4. Repeat the previous step for each element you want to add to the array or collection.
5. You can also fill the array or collection using loops or by reading input from the user or from a file. For instance, you can use a for loop to iterate over all elements and assign values based on some logic or input.
6. Finally, make sure to handle any potential errors or exceptions that may occur while filling out the array or collection.
