Java Closures

Java 7 is going to have lambda expression("closure"). Some people say it's simplification.
Other says no it's harm. Well anonymous classes was a replacement of closures and
as James Gossling says because of time pressure. But the Java culture of programming is formed and
exists a decade. Just try yourself the examples and ask youself:
Is it improve you code? Ask colleges do they understand your code?
Example 1

val SOME 6 =
 withReturn
    (fn return =>
        (app (fn x =>
                 if 0 = x mod 2 then
                    return (SOME x)
                 else
                    print (Int.toString x))
             [1, 3, 5, 6, 7, 9]
       ; NONE))

What's the result??? It's simple isn't it? 135

Example 2

  new Functor(){public Object f(Object x){ ... }}
vs
  (lambda (x) ...)
vs
  new (){f(x){...}}


Example 3

textField.addActionListner( new ActionListener() {
 public void actionPerformed( ActionEvent notUsed ) {
     textArea.append( textField.getText() );
 }
});
vs
textField.addActionListner( ActionListener()
 ( notUsed )
      textArea.append( textField.getText() );
);

Result: As we see from examples we missing type declaration - so missing the idea
of Java as a language. Simplification of lines of code,lines...No the most for you you IDE
does no matter Eclipse, IntelJ or Netbeans. But if you are a vi or notepad geek just
think maybe it's better for you to write on perl or assembler?

Modificator for @Autowire

Is it the same?
@Autowired
public indentifier name
@Autowired
private indentifier name

1. Speed issuer. With a private modificator reflection algorith adds only one additional call which is nano seconds time.
name.setAccessible(true);
2. But with a private modificator you don't break object encapsulation

SLF4J

SLF4J-simple can't be configured via log4j.properties. To configure it use slf4j-log4j12

WINDOW resize handler

public class XXX implements ResizeHandler{
public XXX(){
Window.addResizeHandler(this);
}

@Override
public void onResize(ResizeEvent event) {
//TODO YOUR CODE AFTER RESIZING
}

}
