Java has been a cornerstone of software development for decades, and its flexibility has made it a go-to language for developers all around the globe. This blog discusses the exciting changes and new features that came with Java 8. These changes have changed the way programmers do their jobs.
Prepare to learn about Lambda expressions, the new Date/Time API, and much more, as this article takes a deep dive into the changes between Java 7 and Java 8.
Java 7, often called "Dolphin," was a major upgrade to the Java programming language that came out in July 2011 from Oracle Corporation. After Oracle bought Sun Microsystems, this was the first significant upgrade to Java that Oracle was in charge of. Oracle reached a big milestone with the introduction of Java 7. This showed that Oracle was committed to Java and its future development.
Java 7 comes with a lot of new features and improvements, such as Project Coin's language changes. It also had a better class-loader design, better type interference for generic instances, library support for ECC (elliptic curve cryptography) techniques, and improved Managed Beans.
It is a collection of modest changes to the language that are meant to make developers more productive. It has features like making calls to varargs methods easier, using binary literals, and handling exceptions in more than one way.
In Java 7, the switch statement was changed such that the switch expression may be a String object.
The ability to catch more than one exception in a single catch block, which cuts down on code duplication.
The design of the class-loader was changed to better handle dynamic languages and modularity.
Java 7 made building and utilizing generic types simpler by making it work better with type interference while creating generic instances.
The standard library now supports ECC algorithms, making it easy to employ elliptic curve encryption in Java apps.
Several changes were made to Rowset 1.1 and JDBC 4.1, such as adding support for SQLXML and making metadata support better.
Updates were made in Managed Beans so that they work better with JavaServer Faces and the Java Persistence API.
With Java 7, the try statement automatically manages resources like files and database connections, making their management easier.
Several changes were made to the concurrency and collections APIs in Java 7, which made it simpler to develop code that works well with multiple threads and can be scaled up.
Java 7 included compressed 64-bit pointers, which make 64-bit JVMs use less memory.
After Java 7, the next major version of the Java programming language was Java 8, which had the code name "Spider." Oracle Corporation published it in March 2014, and it included a lot of new features and enhancements to the language, including several long-awaited ones that made functional programming in the language much better.
One of the most important innovations in Java 8 was the addition of lambda expressions, a new way to define functions that makes it simpler to develop code that uses the functional programming paradigm. Other big changes in Java 8 include better type annotations, the addition of default methods for interfaces, and improvements to the Stream API for dealing with collections.
Lambda expressions are a new way to write code in Java that defines functions. They provide a short, powerful approach to describe behavior that may be supplied to methods as a parameter.
Java 8 included support for type annotations, which let developers add more information about types that tools may use for checking, analyzing, and making code.
Interfaces in Java may now contain default methods, which make it possible to introduce new behavior without altering how current implementations use the interface.
The Stream API is a new way to interact with collections, making it simpler to build clear and fast code.
Java 8 included a new Date and Time API that makes working with dates and times more versatile and up-to-date.
Java 8 got rid of the Permanent Generation (PermGen) memory space, which caused Java developers a lot of trouble in older versions.
Java 8 added numerous new ways to interact with arrays, making it easier to process data in parallel.
The Optional class was added to Java 8 to show values that may or may not be present.
The CompletableFuture API in Java 8 makes it simpler to build asynchronous code. It is one of the new APIs for dealing with concurrency.
As developers, one can occasionally have to determine whether a project should use Java 7 or Java 8. Java 7 is still used and supported by a lot of people. However, Java 8 has a lot of new features and updates that may make various apps work better and be more useful.
One of the best things about Java 8 is that it now has lambda expressions, which make writing code for specific tasks simpler and shorter. Java 8 adds the new Stream API, which gives developers a sophisticated way to work with groups of data. In Java 8, there are other improvements to security, compatibility with dates and times, and the performance of the JVM.
In other situations, such as when Java 8 systems or libraries don't work well with each other, Java 7 may still be the ideal choice for some projects. Last but not least, whether one utilizes Java 7 or Java 8 depends on the needs of their projects and the resources they have.
The most important differences between Java 7 and Java 8 are discussed in this article, along with how these changes have affected the way programmers do their work. With the inclusion of Lambda expressions, a new Date/Time API, and changes to the Stream API that make it easier to work with collections, Java 8 is a big improvement over its predecessor.
If someone wishes to develop code in Java, it's important to choose the best version that fits their needs. Knowing the differences between Java 7 and Java 8 can help developers and organizations decide which one to use, whether they need to work with older systems or want to use the latest features.

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.
A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!
Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
Ever wondered how computer programming works, but haven't done anything more complicated on the web than upload a photo to Facebook?
Then you're in the right place.
To someone who's never coded before, the concept of creating a website from scratch -- layout, design, and all -- can seem really intimidating. You might be picturing Harvard students from the movie, The Social Network, sitting at their computers with gigantic headphones on and hammering out code, and think to yourself, 'I could never do that.
'Actually, you can. ad phones on and hammering out code, and think to yourself, 'I could never do that.'
