In this video, Doug Winnie shows how to create a collection of values using an array. Then Doug shows how to work with individual values in the array after it is created using bracket notation and the element index number.
- Arrays are collections that can…group objects together under a single name.…In Java, arrays can hold objects of the same type,…which is different than other programming languages.…To create an array, you start by providing…the type of the value that the array will hold.…Then you add an opening and closing bracket.…Then you assign multiple values to the array…after you give that array a name.…First, you need to say that you're…creating a new typed array.…Then start with an opening curly brace,…and enter the first value.…
In this case, I'll create a string.…Then, separate each value with a comma.…Close with a second curly brace,…and then a semicolon.…This array has four elements,…and each element has an index number…that we can use to access each element.…The first element is zero.…So the string, "Doug," is element zero…in the array named myArray.…There are multiple ways we can access an array.…You can access the entire collection…of values as a single set.…
Or, you can pinpoint specific items inside of it.…To send to the console,…
