Downloading and Installing JDK 1.8

This section describes how to download and install Java SE Development Kit (JDK) 8u45 on a Windows system.

Since Android apps are developed in Java language, you need to have a copy of JDK (Java Development Kit) installed on your computer first. The latest version of JDK is Java SE Development Kit 8u45. Here is what I did to download and install Java SE Development Kit 8u45 on my Windows 7 system.

1. Open the Java SE Download page with this URL: http://www.oracle.com/technetwork/java/javase/downloads/.

2. Click the download button below "JDK" in the "Java SE 8u45" section. You will see a new page with a list of different download files of "Java SE Development Kit 8u45".

3. Click the "Accept License Agreement" option.

4. Locate the line "Windows x86 175.98 MB" and click on "jdk-8u45-windows-i586.exe" to start download.

5. Save the download file to C:\download\jdk-8u45-windows-i586.exe and wait for the download to finish.

6. Double-click on C:\download\jdk-8u45-windows-i586.exe to start the installation wizard. The installation wizard will guide you to finish the installation.
