The other day, when I was trying to compile all the Tame Swing examples,
I had a problem running one of the examples. The problem was that I was
running the example in Eclipse, and I was getting an error message
showing the Eclipse (the JVM really) couldn't find the icon image files.
I thought I had everything configured properly, but still I
kept getting the same error message. Finally I decided to look at my
Java system properties and see what my build path really looked like. I
couldn't think of the right Java property to show the build path, so
instead of trying to print just the one Java property, I decided to
print all the Java properties, then dig through them manually. You print
Java system properties with the
System.getProperties() method.
Here's the code I used to print all the Java system properties:
Properties p = System.getProperties();Enumeration keys = p.keys();while (keys.hasMoreElements()) { String key = (String)keys.nextElement(); String value = (String)p.get(key); System.out.println(key + ": " + value);} |
And here's the output from that section of code:
