In this article we displayed our system properties via Tomcat. We were curious, though, how to retrieve these directly through Java. Here is how you can do this:
[usr-1@srv-1 java]$ cat FirstProperties.java
public class FirstProperties {
public static void main(String[] args) {
System.out.println("System Information: \n");
System.out.println("Operating System: ");
System.out.println(System.getProperty("os.name"));
System.out.println("\nArchitecture: ");
System.out.println(System.getProperty("os.arch"));
System.out.println("\nOperating System Version: ");
System.out.println(System.getProperty("os.version"));
System.out.println("\nJava Virtual Machine Version: ");
System.out.println(System.getProperty("java.vm.version"));
}
}
[usr-1@srv-1 java]$ javac FirstProperties.java
[usr-1@srv-1 java]$ java FirstProperties
