I've been playing around with Scala in the last few days... I must say that the Scala syntax is really nice and concise - it really works hard to eliminate the boilerplate code we all spend far too much time writing.

If you don't believe me: see for yourself (it's an extreme example, I know - but it goes to show how a little change can go a long way). The magic that's going on here is that variables declared in the constructor will automagically become class properties. A lovely little feature.

Scala:

class DBConnectionInfo( var url:String, var username:String, var password:String ) {}

Java:

public class DBConnectionInfo {

	private String _url;
	private String _username;
	private String _password;

	public DBConnectionInfo( String url, String username, String password ) {
		setUrl( url );
		setUsername( username );
		setPassword( password );
	}

	public void setUrl( String _url ) {
		this._url = _url;
	}

	public String url() {
		return _url;
	}

	public void setUsername( String _username ) {
		this._username = _username;
	}

	public String username() {
		return _username;
	}

	public void setPassword( String _password ) {
		this._password = _password;
	}

	public String password() {
		return _password;
	}
}
