Project Coin: A set of small language changes that simplify common programming tasks, such as using strings in switch statements, using diamond syntax for generic types, using try-with-resources statements, etc.
The Fork/Join Framework: A new framework for parallel programming that allows developers to write concurrent applications that can take advantage of multiple processors.
The NIO.2 API: A new API for file and network I/O that supports asynchronous operations, symbolic links, file attributes, etc.
The InvokeDynamic bytecode instruction: A new instruction that supports dynamic languages on the Java Virtual Machine (JVM) by allowing method invocation to be resolved at runtime.
The G1 Garbage Collector: A new garbage collector that aims to provide high throughput and low latency for applications that require large heaps.

Sign in with your Oracle account or create one
Before you can download the installer, you need to sign in with your Oracle account or create one if you don't have one already. You can do this by clicking on the Sign In button on the top right corner of the page. You will be redirected to a login page where you can enter your username and password or create a new account.
After you sign in, you will be asked to accept the license agreement for JDK 1.7. You need to check the box that says I reviewed and accept the Oracle Technology Network License Agreement for Oracle Java SE and then click on the Download button next to the installer that you chose.
The download will start automatically and you will see a progress bar on your browser. Depending on your internet speed, it may take a few minutes to complete the download.
How to install JDK 1.7?
To install JDK 1.7, you need to follow these steps:
Run the installer and follow the steps
After the download is finished, you need to run the installer by double-clicking on the file that you downloaded. You may see a security warning asking you if you want to run this file. You need to click on Run to proceed.
The installer will launch and you will see a welcome screen. You need to click on Next to continue.
Choose the installation location and options
The installer will ask you to choose the installation location for JDK 1.7. By default, it will be C:\Program Files\Java\jdk1.7.0_80.

However, we recommend that you keep the default location unless you have a specific reason to change it.
The installer will also ask you to choose the installation options for JDK 1.7. By default, it will install both the JDK and the JRE. The JDK is the development kit that contains the tools and libraries for Java development, while the JRE is the runtime environment that contains the components for running Java applications. You can uncheck any of these options if you don't want to install them, but we recommend that you keep them both checked unless you have a specific reason to uncheck them.
After you choose the installation location and options, you need to click on Next to continue.
Wait for the installation to complete

Set up an environment variable for JDK 1.7
An environment variable is a name-value pair that is stored in your system and can be accessed by other programs or processes. You need to set up an environment variable for JDK 1.7 so that other programs or processes can find it and use it.

In the System window, click on Advanced system settings on the left side panel.
In the System Properties window, click on the Advanced tab and then click on Environment Variables...
In the Environment Variables window, under System variables, click on New...
In the New System Variable window, enter JAVA_HOME as the Variable name and C:\Program Files\Java\jdk1.7.0_80 as the Variable value (or whatever location you chose for the installation location). Then click on OK.
You have now created an environment variable for JDK 1.7 called JAVA_HOME.
Add JDK 1.7 to the system path
The system path is a list of directories that are searched by your system when you execute a command or a program. You need to add JDK 1.7 to the system path so that you can use the tools and libraries of JDK 1.7 from any directory or location.
To add JDK 1.7 to the system path, you need to do the following:
In the same Environment Variables window, under System variables, look for the variable called Path and click on Edit...
In the Edit System Variable window, append ;%JAVA_HOME%\bin to the end of the Variable value. This will add the bin directory of JDK 1.7 to the system path. Then click on OK.
Click on OK in the Environment Variables window and then click on OK in the System Properties window to close them.
You have now added JDK 1.7 to the system path.
Verify the JDK 1.7 installation
To verify that you have successfully installed and configured JDK 1.7, you need to do the following:
Open a command prompt by clicking on the Start button and then typing cmd in the search box and pressing Enter.
In the command prompt, type java -version and press Enter. You should see something like this:
java version "1.7.0_80" Java(TM) SE Runtime Environment (build 1.7.0_80-b15) Java HotSpot(TM) 64-Bit Server VM (build 24.80-b11, mixed mode)
