Differences Between Java 7 And 8

Last Updated on March 19, 2022 by QCity Editorial Stuff

Java 7 and 8 are two of the most popular java programming languages. There are many differences between these two different versions, which is why it is important to know what they are so you can make an informed decision about which one to use. Java 7 was released in July 2011, while Java 8 was released in March 2014. It’s important to note that not all features of Java 8 will work on older computers running Windows XP or Mac OS X 10.6 Snow Leopard because those operating systems don’t support them. If your computer doesn’t support the new features then there isn’t any reason for you to upgrade yet – but if it does then updating should be a high priority.

The Java programming language is one of the most widely used languages in the world with over 9 million developers using it today. It has seen major updates since its first release in 1995. The latest version, Java 8, was released on March 18th, 2014, and contains many changes that improve developer productivity as well as add new features to improve code security. This article will look at some of these differences between java 7 and 8. 

Java 8 was the first new release of Java in six years. It contains a lot of changes and improvements to the language, but it is not backward compatible with Java 7. This blog post talks about some of the major differences between java 7 and 8, such as how lambda expressions work and what makes them different from anonymous classes.

What Is Java 7?

Java 7 is a new version of Java that has been released by Oracle. The release date was July 28th, 2011 and it contains many interesting features such as JSR-292 which provides support for the latest web standards, including HTML5 and CSS3 to name a few. Java 7 also includes enhancements in security with JSR-250, the addition of Nashorn JavaScript engine to provide access to all scripting languages from within a Java application or applet, and an improved garbage collector called G1. There are many other improvements as well.

Java 7 is a significant update to the Java programming language and brings numerous new features to both developers and end-users. The introduction of Project Coin in Java SE7 has been one of the most discussed topics in Java circles these days. One of the major goals of this project was to add small but highly useful utilities that could be added without breaking compatibility with older versions of Java SE. 

What Is Java 8?

Java 8 is a new version of Java that was released on 18 March 2014. It brings several new features to the language, most notably lambda expressions and method references which are used to provide better support for multicore hardware, as well as NIO.2, JAX-WS 2.2, and more. If you want an in-depth look at these features check out my blog post here.

Java 8 is a programming language that was developed to be more robust, powerful, and easier to maintain. Java 8 has four major changes: Lambda expressions, functional interfaces, method references, and default methods. These new features are all designed to make the code simpler and easier for developers to read. 

The most interesting of these new features is lambda expressions which allow programmers to write shorter code with less nesting. This helps with both maintenance as well as readability of the codebase because it allows for an overview without having to scroll down through long blocks of nested statements.

10 Differences Between Java 7 And 8

1. Java 7 is the most popular version of java, with more than 60% market share.

2. Java 8 has a new JVM called “JRockit” that can run on Windows and Linux.

3. The lambda expression was introduced in java 8. 

4. There are two new languages – java card and JCL.

5. Java 8’s compiler is now invoked with the command-line option “-source 1.8”. 

6. In java 7, it is possible to have multiple class files with the same name but different extensions (.java vs .class).

7. Java 7 is a compiled programming language, while java 8 is an interpreted one.

8. Java 7 requires the use of semicolons at the end of each statement, while java 8 does not require them.

9. In java 7 you can only have a single class per file, but in java 8 you can have multiple classes in one file.

10. In java 7 there are no default values for primitives and arrays, but in java 8 they exist.

Interesting Statistics Or Facts Of Java 7 

1. Java 7 has a new version of the JVM.

2. It is possible to write code in java and compile it with javac for different platforms such as Windows, Linux, Mac OS X, Solaris, and more.

3. The compiler can be used to convert code into executable files that are then executed by an interpreter or just-in-time (JIT) compiler.

4. Java 7 introduces Nashorn – a JavaScript engine written in Java that allows developers to use JavaScript on the server-side.

5. There is support for Unicode 6.

6. The garbage collector has been improved so that it will work better with large heaps.

Interesting Statistics Or Facts Of Java 8

1. Java 8 is the first release of java to include lambdas.

2. The lambda syntax in Java 8 is similar to C#’s anonymous delegates.

3. Java 8 can be compiled with or without generics.

4. Lambda expressions are not limited to single statements, but can contain multiple statements and even yield values as a function would. 

5. Lambda expressions cannot refer to local variables in their enclosing scope (except final variables) – they are only allowed access to parameters passed into them and any constants that have been declared as part of the expression.

6. You can use an underscore character before a variable name when declaring it within a lambda body for readability purposes – this indicates that you don’t intend for the variable’s value to change during the execution of the code block.

Conclusion About The Differences Between Java 7 And 8

Java 8 has many new features that simplify the development process, but it does not have all of the functionality found in java 7. If you are using an older operating system or would like to use a feature from java 7 (like generics), then your best option is to stay with java version 7. For example, if you want to take advantage of lambda expressions and default methods for interfaces, which were introduced in Java SE 8; or if you need access to RawTypes because they make working with legacy code much easier, then this blog post may be helpful.
