Assume that x is a double that stores 0.362491. To output this value as 36%, you could use the NumberFormat class with NumberFormat nf = NumberFormat.getPercentInstance( ); Which of the following statements then would output x as 36%?
A) System.out.println(x);
B) System.out.println(nf);
C) System.out.println(nf.x);
D) System.out.println(nf.format(x));
E) System.out.println(format(x));

D) nf is an object and so must be passed a message to use it. The method to format a float or double is called format and the value to be formatted is the parameter passed to format.
