JDK Tutorials - Herong's Tutorial Examples

∟Downloading and Installing JDK 1.8.0 on Windows

This section provides a tutorial example on how to download and install JDK 1.8.0 (Java SE 8) on a Windows 7 system. A simple Java program was entered, compiled, and executed with the new JDK installation.

Downloading and installing JDK 1.8.0 (Java SE 1.8) on a Windows system is easy. Here is what I did on my Windows 7 system in year 2014:

To test the installation, open a command window to try the java command. If you are getting the following output, your installation is ok: 

C:\herong>\progra~1\java\jdk1.8.0\bin\java -version
java version "1.8.0"
Java(TM) SE Runtime Environment (build 1.8.0-b132)
Java HotSpot(TM) Client VM (build 25.0-b70, mixed mode, sharing)

Once JDK is installed, you can try to use it to compile and execute a simple Java program:

1. Use Notepad to enter the following Java program into a file called Hello.java: 

class Hello {
   public static void main(String[] a) {
      System.out.println("Hello world!"); 	
   }
}

2. Then compile this program in a command window with the javac command: 

C:\herong>\progra~1\java\jdk1.8.0\bin\javac Hello.java

3. To execute the program, use the java command: 

C:\herong>\progra~1\java\jdk1.8.0\bin\java Hello
Hello world!

Congratulations, you have successfully entered, compiled and executed your first Java program with JDK 1.8.0.
