UML Sample

[Vu Pham]

Hi all,

As you knew, open source project always contains source code in it. I'm finding a project similar like open source project but contains UML design of that project. I'm learning UML, so I want to have a sample real project with UML design. Please help me if you know about that. Thanks very much

class TestReadData {
  public static void main(String[] args) {
    String text = ReadData.readText("Write a text: ");
    double decimal = ReadData.readDecimal("Write a decimal: ");
    int integer = ReadData.readInteger("Write an integer: ");
    System.out.println("You wrote this: ");
    System.out.println(text);
    System.out.println(decimal);
    System.out.println(integer);
    System.exit(0);
  }
}
 

Hello JavaRanch
The above codes will speak of its valid UML design.
Hope this suffices the request.

Are you confused my question :roll:

I highly recommend the book "UML for Java Programmers" by Robert C. Martin.

Indeed the present day strategy reads " give the end result first and then go for Checking !! "
Yes ,you can visit now:www.rational.com/uml;
and have plethora of information on uml and then use the above example to confirm its validity,and have more examples by buying the  book as stated  
besides learn online itself from this exhiliarting site.
Thanks
