This section provides a tutorial example on how to download and install JDK 1.7.0 (Java SE 7) on a Windows XP system. A simple Java program was entered, compiled, and executed with the new JDK installation.
Downloading and installing JDK 1.7.0 (Java SE 1.7) on a Windows system is easy. Here is what I did on my Windows 7 system:
To test the installation, open a command window to try the java command. If you are getting the following output, your installation was ok:
herong> \progra~1\java\jdk1.7.0_45\bin\java" -version java version "1.7.0_45" Java(TM) SE Runtime Environment (build 1.7.0_45-b18) Java HotSpot(TM) Client VM (build 24.45-b08, 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:
herong> \progra~1\Java\jdk1.7.0_45\bin\javac" Hello.java
3. To execute the program, use the java command:
herong> \progra~1\Java\jdk1.7.0_45\bin\java" Hello Hello world!
Congratulations, you have successfully entered, compiled and executed your first Java program with JDK 1.7.0.
