Como q eu fa�o p/ compilar a Classe
Time1.java criando o seguinte pacote
com.deitel.jhtp3.ch08?
Estou utilizando Windows 98 SE e
j2sdk1.4.0.
// Time1.Java
package com.deitel.jhtp3.ch08;
import java.text.DecimalFormat; // used for number formatting // This class maintains the time in 24-hour
format
public class Time1 extends Object { private int hour; // 0 - 23 private int minute; // 0 - 59 private int second; // 0 - 59 // Time1 constructor initializes each
instance variable
// to zero. Ensures that each Time1 object starts in a // consistent state. public Time1() { setTime( 0, 0, 0 ); } // Set a new time value using
universal time. Perform
// validity checks on the data. Set invalid values to zero. public void setTime( int h, int m, int s ) { hour = ( ( h >= 0 && h < 24 ) ? h : 0 ); minute = ( ( m >= 0 && m < 60 ) ? m : 0 ); second = ( ( s >= 0 && s < 60 ) ? s : 0 ); } // Convert to String in universal-time
format
public String toUniversalString() { DecimalFormat twoDigits = new DecimalFormat( "00" ); return
twoDigits.format( hour ) + ":"
+
twoDigits.format( minute ) + ":" + twoDigits.format( second ); } // Convert to String in standard-time
format
public String toString() { DecimalFormat twoDigits = new DecimalFormat( "00" ); return ( (hour == 12 || hour == 0) ? 12 : hour % 12 ) + ":" + twoDigits.format( minute ) + ":" + twoDigits.format( second ) + ( hour < 12 ? " AM" : " PM" ); } } |
