Semicolon evolution

On Kay Horstmann's site lies an amusing vision of the evolution of PL.

1980: C
printf("%10.2f", x);

1988: C ++
cout << setw(10) << setprecision(2) << showpoint << x;

1996: Java
java.text.NumberFormat formatter = java.text.NumberFormat.getNumberInstance();
formatter.setMinimumFractionDigits(2);
formatter.setMaximumFractionDigits(2);
String s = formatter.format(x);
for (int i = s.length(); i < 10; i++) {
System.out.print(' ');
}
System.out.print(s);

2004: Java
System.out.printf("%10.2f", x);

2008: Scala and Groovy
printf("%10.2f", x)

(Thanks to Will Iverson for the update. He writes: “Note the lack of semi-colon. Improvement!” )

Note the loss of a semicolon. Impressive Achievement Progress!
