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!
