CIS 160 printf exercise

• Use printf to format output

The format strings for each of the printf method calls below are incomplete. Fill in the format strings to get the exact same output as the sample output displayed at the bottom of this page.

public class PrintfExercise { public static void main(String[] args) { int a = 17, b = 127; double x = 123.45678901234; System.out.printf("%n"); System.out.printf("a: %%n", a); System.out.printf("b: %%n", b); System.out.printf("x: %%n", x); System.out.printf("x: %%n", x); System.out.printf("x: %%n", x); System.out.printf("% is % of %%n", 5, (5 * 100 / 10), 10); } }

This is the printf exercise a: 17 b: 000000127 x: 123.46 x: 123.4568 x: 1.23e+02 5 is 50% of 10
