    Re: Making a web site in Java

    Then honestly, it might be better to just start with static html and css. It doesn't sound like you have any use for a server (other than to host your files), and all you really need is a collection...

    Re: Making a web site in Java

    Not really. Flash is on its way out, and html5, css, and javascript are the standard frontend "languages" as they have the most cross-platform support (think mobile devices here).

    Re: Making a web site in Java

    The word "dynamic" is one of those words that's thrown around so much that it doesn't have any actual meaning anymore.

  11. Re: cannot find symbol:getSystemCpuLoad()

    You need to post an MCVE that demonstrates exactly what you're doing. This works fine for me:


    import java.lang.management.ManagementFactory;
    import com.sun.management.OperatingSystemMXBean;
    ...
  12. Re: cannot find symbol:getSystemCpuLoad()

    Are you sure the type of osBean is com.sun.management and not java.lang.management?

    Re: nary tree from string

    Well, if you're getting errors it's obviously not correct. What exact line is the error on? What index are you trying to access? How many indexes does the array on that line have? What caused the...

    [SOLVED] Re: cannoot find symbol

    It does. This is why you should always use curly brackets with if statements and for loops.
  16. Re: My program has a error, please help me!

    That is not how this works. Post an MCVE and the specific text of the error, and we'll go from there.

    [SOLVED] Re: cannoot find symbol

    Again, the compiler doesn't "hint" anything. It gives you very specific errors.

    What symbol can't it find? You'll have much better luck if you post an MCVE instead of incomplete code.

    [SOLVED] Re: Unexpected type

    Okay, fair enough. You're still using the ternary operators incorrectly. The ternary operator must evaluate to a value, not an expression. So you can't do this:
