Archived: Download and Install Latest JDK 10 on Windows
This section provides a tutorial example on how to download and install the latest version JDK, which contains the HotSpot JVM, on a Windows system. A simple Java program was entered, compiled, and executed to verify the JDK installation.
In order try the HotSpot JVM, I downloaded and installed JDK 10 (Java SE 10) on my Windows system:
To test the installation, open a command window to try the "java" command. If you are getting the following output, your installation has completed correctly.
herong> \Progra~1\Java\jdk-10.0.1\bin\java -version java version "10.0.1" 2018-04-17 Java(TM) SE Runtime Environment 18.3 (build 10.0.1+10) Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.1+10, mixed mode)
Once the 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:
herong> \Progra~1\Java\jdk-10.0.1\bin\javac Hello.java
3. To execute the program, use the "java" command:
herong> \Progra~1\Java\jdk-10.0.1\bin\java Hello Hello world!
Cool, I have successfully:
