public class DateFirstTry { public String month; public int day;
public int year;
public void writeoutput(){System.out.println(month+" "+day+","+year);}
public void makeItNewYear(){month ="January";day=1;
}} public class DateFirstTryDemo {public DateFirstTryDemo() {}
public static void main(String[] args){
DateFirstTry date1,date2;
date1=new DateFirstTry();
date2=new DateFirstTry();
date1.month="December";
date1.day=31;date1.year=2007;
System.out.println("date1:");
date1.writeoutput();
System.out.println("New year:");
date1.makeItNewYear();
date1.writeoutput();date2.month="July";
date2.day=4;
date2.year=1776;
System.out.println("date2:");
date2.writeoutput();
System.out.println("New year:");
date2.makeItNewYear();
date2.writeoutput();}}
結果:
date1:December 31 2007
NewYear of date1 is:January 1 2007
date2:July 4 1776
NewYears of date2 is:January 1 1776
