Consider the following code snippet:
console.printf("%d %1$x %1$o", 16);
assuming that console is a valid Console object, what will it print?
A. this program crashes after throwing an IllegalFormatException B. this program crashes after throwing ImproperFormatStringException C. this program prints: 16 16 16 d. this program prints: 16 10 20
d.
In the format specifier, "1$" refers to first argument, which is 16 in this printf statement.
hence "%1$x" prints the hexadecimal value of 16, which is 10.
Further, "%1$o" prints the octal value of 16, which is 20.
hence the output "16 10 20" from this program.
