Chapter 3 Exercise

Learning must pay attention to the foundation, so I am so careful to squat these things, and even the exercises is a one. Although I feel a little annoying, but for experience, I continue to write. There are several questions that can't come out. The 23rd question is made as required, but the results do not understand. 1.

// ES01.java import tio *;. Class ES01 {public static void main (String [] args) {int intQuarter, intDime, intNickle, intPenny; float fltSum, fltQuarter = 0.25F, fltDime = 0.10F, fltNickle = 0.05F , Fltpenny = 0.01F; System.out.Println ("please input the number of quarter," "DIME, NICKLE and PENNY:"); int quarter = console.in.readint (); intDime = console.in.readint ); intNickle = Console.in.readInt (); intPenny = Console.in.readInt (); fltSum = intQuarter * fltQuarter intDime * fltDime intNickle * fltNickle intPenny * fltPenny; System.out.println ( "$" Fltsum);}}
