Please help me use this LookAndFeel in java.

I have downloaded quauqa-5.4.1.zip

I tried the following, but it's giving me exception in thread:-

package ch.randelshofer.quaqua;

class Account extends JFrame
{
   @SuppressWarnings("unchecked")

    public static void main (String [] fisd)
    {       
       Account acc=new Account();
       acc.setVisible(true);
       acc.setSize(900,600);

       java.awt.EventQueue.invokeLater(new Runnable()
       {
         public void run() {
             new Account().setVisible(true);
              try {
                System.setProperty(
                 "Quaqua.tabLayoutPolicy","wrap"
                         );
                  UIManager.setLookAndFeel("ch.randelshofer.quaqua.QuaquaLookAndFeel");
        }
             catch (Exception e)
        {
           System.err.println("Oops!  Something went wrong!");
        }
          }
       });
          }
}

What exception. Add a printStacktrace to that catch block and post that result.

I have a feeling, though, that's its a "classnotfound". Include the jarfile for that api on the classpath.

This Exception :(

Uhm, is Account (your class) supposed to be in the package "ch.randelshofer.quaqua"?

If it is, you need to call java from the directory that contains the "ch" directory (from the above package path) and use ch.randelshofer.quaqua.Account on the command line, not just Account.

You seemingly need to re-learn some of the basics (I can only assume you have been "learning" on an IDE, and so know next to nothing about how the JVM actually works).

Yes Account is class name. But is not in the package.
How to put Account in the package?

:( i know.. I'm not so good in java. It is my first time learning this. I have a school management project to submit by this month

Just need to give it a fresh look and unique look. I asked my java teacher to help me with this but he hasn't heard of quaqua.

I have less knowledge of this LookAndFeel. Just help me with this please.

This has nothing to do with "quaqua". It has to do with the fact that you declared that package in your class. If you don't want it in that package (and I'm fairly sure it shouldn't be), don't declare it as being in that package.

i did declare the package inside the class. It is giving that thread exception. let me show you the whole code for Account.java

We crossed posts. Please read my last about the specifying the commandline.

yes i read. I typed in cmd. It gave the same exception about thread -- ClassNotFound :(

hey i read. it didnt work, it's giving the same exception

Please copy the full contents of the command prompt screen for when you get the error and paste it here.

What is the full path to the Account.class file?

C:\Users\User>java -cp quaqua.jar ch.randelshofer.Account

Please go back and read my post about using the -cp option. You need to specify the current directory with a .

What is the full path to the Account.class file?

C:\Users\User\Documents\FISD PROJECT\Account.java

That's not going to work. But you show the .java file, not the .class file??
The path to the Account.class file MUST match the package path. EXACTLY.

i dont get it. Listen, just see Account.java codes and check whether i have imported the quaqua package accordingly or not. Also check main function. And umm... how do i actually use quaqua in Account.java?

Sorry, I know nothing about quaqua.
I was trying to correct the comandline so you could start the execution of the Account class.

Are you able to compile the Account.java file and get a Account.class file?
You can NOT execute the Account.java file. You must create an Account.class file.

Yes it is compiling and there is .class file
This was before i imported quaqua so that's why .class file is there
Anyway, just forget about this quaqua. It keeps giving me that thread exception. It's totally hopeless, won't work.
I guess i've to just use WindowsLookAndFeel.

Thanks for your help, I appreciate it alot

As you've already been told, this has nothing to do with "quaqua". This has to do with the package you've given to your class (which it shouldn't have if that is a package in quaqua, which I can only assume it is), with the way you're defining your classpath, and with the way you are designating your main class, which has already been said.

Uhm, is Account (your class) supposed to be in the package "ch.randelshofer.quaqua"?

If it is, you need to call java from the directory that contains the "ch" directory (from the above package path) and use ch.randelshofer.quaqua.Account on the command line, not just Account.

You seemingly need to re-learn some of the basics (I can only assume you have been "learning" on an IDE, and so know next to nothing about how the JVM actually works).

hey i just wanted to give it this:-

UIManager.setLookAndFeel("ch.randelshofer.quaqua.QuaquaLookAndFeel");

or this:-

UIManager.setLookAndFeel(QuaquaManager.getLookAndFeelClassName());

and this in main function:-

//@SuppressWarnings("unchecked")

	public static void main (String [] fisd)
	{
		//Account acc=new Account();
		//acc.setVisible(true);
		//acc.setSize(900,600);

  		java.awt.EventQueue.invokeLater(new Runnable()
  		{
            public void run() {
                new Account().setVisible(true);
              try {
	    		    System.setProperty(
	    	        "Quaqua.tabLayoutPolicy","wrap"
        			);
    				UIManager.setLookAndFeel("ch.randelshofer.quaqua.QuaquaLookAndFeel");
   					}
					catch (Exception e)
					{
                                                e.printStackTrace()
  					}
	            }
	        });
	    }

if you know the correct methods then please tell me. All i want is that my frames should have quaqua theme.

I tried the above codes and it aint working. See Account.java in page 1 for brief description.

You have been told what's causing the error you're getting multiple times and, as yet, it has nothing to do with any of the code just posted. Since you simply can't seem to understand what you're being told I'm going to stop trying to tell you.

:(

Again it has nothing to do with quaqua.
See http://download.oracle.com/javase/tutorial/getStarted/index.html

ohh so what you're saying is that i cant do quaqua in java?

No I am not saying that! I am finished talking to the wall now, goodbye!

:'( you are so rude. Just beacuse I don't understand doesn't mean you turn your back.
I hope I figure it out by myself as soon as possible. Im sorry for distubing you. I'll make sure it wont happen again.

No, I am not rude, I am honest. And, when I tell someone the same thing four or five times (and say it clearly) and they still don't understand (or at least act as if they don't), then I stop telling them as it is not doing either of us any good and is only going to lead to frustation on both parts and bad feelings on their part.
