Console API – OCPJP 6

February 2, 2014 by Krishna Srinivasan Leave a Comment

5) What will be the output of the following program?

[code lang=”java”]
package console;
public class Ques02 {
public static void main(String[] args) {
int anInt = 100;
double aDouble = 100.00;
System.console().format("%2d – %1f", anInt, aDouble);
}
}
[/code]

  1. The program will output ‘100.000000 – 100’.
  2. The program will output ‘100 – 100.000000’.
  3. The program will throw a IllegalFormatConversionException at run-time.
  4. The program will output ‘100 – 100’.

5) b.

Here the ordering of the arguments (anInt and aDouble) matters, not the formatting strings ‘%2 – %1d’. So the first output will be the value of anInt variable followed by a hyphen (‘-‘) followed by the value of aDouble variable.
