String Memory Internals by Tomasz Murkiewicz. The main point to understand here is the distinction between String Java object and its contents - char[] under private value field. String is basically a wrapper around char[] array, encapsulating it and making it impossible to modify so the String can remain immutable. Also the String class remembers which parts of this array is actually used. This all means that you can have two different String objects (quite lightweight) pointing to the same char[].

Since its initial release as AngularJS in October 2018, Google's Angular framework has become one of the most popular means for building front-end web applications. Now on Angular 8, this powerful framework allows developers to build browser-based applications and mobile apps using the TypeScript langauge.
With different applications and dev teams across the globe using different versions of Angular, we've compiled the best articles and tutorials on DZone about each version of this popular framework. So, no matter what version of Angular your team uses, you're sure to find something here to help you up your Angular game.

For this year’s big data survey, we received 459 responses with a 78% completion rating. Based on this response rate, we have calculated the margin of error for this survey to be 5%. Using the data from these responses, we've put together an article on how various sub-fields of big data are on the rise and how devs are becoming more data-driven.

Despite the prominence of DevOps in the software industry, less than half of respondents (46%) told us that their organization has an officially designated DevOps team. This lack of an official DevOps team in many organizations manifests itself in the unequal distribution of code deployments. Whereas in DevOps, development and operations teams are meant to work cooperatively to create and release code, 57% of respondents reported that only development teams perform code deployments in their organization. 42% reported this as an operations function, and 32% told us that release engineers handle code deployments. Despite these trends, 54% reported management as a DevOps enabler.
Throughout this series, we've been building an application to keep track of the National Parks we've visited. In the last article, we looked at how to transfer data between two Express-based web pages using the body-parser middleware. In this post, we'll look at how to style our pages and make them responsive using the open source Bootstrap framework.
Quick PSA: If you're smart, you'll do what I didn't and wait to make any CSS tweaks until after Bootstrap has been properly integrated and all our elements are responsive.
