Complete the statement to produce the following output. Output the value of the variable userNum, not the literal 46.

Hint: Typing "I have 46 books." is a common mistake, as is "I have userNum books.". See above section for how to output a variable's value.

I have 46 books.

System.out.print(                   );

It is possible to do more than one method

First Solution ,Can used println as like the below Example:

System.out.println("I have "   userNum  " books");

Second Solution , Can used printf as like the below Example:

System.out.printf("I have %d books",userName);

Note : To explain the two solution

• println is short for "print line", meaning after the argument is printed then goes to the next line

• printf is short for print formatted.

  • %s formats strings.
  • %d formats decimal integers.
  • %f formats floating-point numbers.
  • %t formats date/time values.
