Hmmm...you seem to be missing some keys from your output, are you sure you pasted the entire output?

public class Main {

    public static void main(String[] args) {
    // write your code here
        System.out.printf("This is the classpath: %s %n",
                System.getProperty("java.class.path"));
        Set<String> propNames = new TreeSet<String>(System.getProperties().stringPropertyNames());
        for (String propertyName : propNames) {
            System.out.printf("%s is %s %n",
                    propertyName,
                    System.getProperty(propertyName));
        }
    }
