We now need to change all lines to a new object - its painful. I now try and stay away from raw data. It rarely makes a noticeable difference.
Hotspot is an amazing piece of technology and you should never try and second guess. Just try to write simple, maintainable code and Hotspot will do the rest.
Which may be a different one than your customers. Remember that in Java a List is an abstract, not a concrete data type. You should declare the strings as a List, and then initialize it using the ArrayList implementation. Access speed is virtually identical to an array, with the additional advantages of being able to add and subtract elements to a List although this is an O n operation with an ArrayList and that if you decide to change the underlying implementation later on you can.
For example, if you realize you need synchronized access, you can change the implementation to a Vector without rewriting all your code. In fact, the ArrayList was specifically designed to replace the low-level array construct in most contexts.
Since arrays keep all the data in a contiguous chunk of memory unlike Listswould the use of an array to store thousands of strings cause problems?
In Java, all collections store only references to objects, not the objects themselves. Both arrays and ArrayList will store a few thousand references in a contiguous array, so they are essentially identical.
You can consider that a contiguous block of a few thousand bit references will always be readily available on modern hardware.
This does not guarantee that you will not run out of memory altogether, of course, just that the contiguous block of memory requirement is not difficult to fufil.You can also gift Pluralsight membership to your friend or colleague as a holiday present, he would thank you every time he needs to learn a new technology.
