public class MyDate {
private int year;
private int month;
private int day;
public MyDate(int year, int month, int day) {
this.year = year;
this.month = month;
this.day = day;
}
public int getYear() {
return year;
}
public void setYear(int year) {
this.year = year;
}
public int getMonth() {
return month;
}
public void setMonth(int month) {
this.month = month;
}
public int getDay() {
return day;
}
public void setDay(int day) {
this.day = day;
}
@Override
public String toString() {
return year + "年" + month + "月" + day + "日";
}
}

public class MyTime {
private int hour;
private int minute;
private int second;
public MyTime(int hour,int minute,int second){
this.hour = hour;
this.minute = minute;
this.second = second;
}
public int getHour() {
return hour;
}
public void setHour(int hour) {
this.hour = hour;
}
public int getMinute() {
return minute;
}
public void setMinute(int minute) {
this.minute = minute;
}
public int getSecond() {
return second;
}
public void setSecond(int second) {
this.second = second;
}
@Override
public String toString() {
return hour + "时：" + minute + "分：" + second + "秒";
}
}

public class FullTime{
private MyDate date;
private MyTime time;
public FullTime(MyDate date,MyTime time){
this.date = date;
this.time = time;
}
public MyDate getDate() {
return date;
}
public void setDate(MyDate date) {
this.date = date;
}
public MyTime getTime() {
return time;
}
public void setTime(MyTime time) {
this.time = time;
}
@Override
public String toString() {
return date.toString() + time.toString();
}
}

追问怎么在另一个类里面显示年月日时间

追答直接调用FullTime中的toString方法就可以了啊

...这是求全码的节奏?
话说2个对象的toString都有了，直接拼起来不行吗...
再不想，FullTime的toString里面获取自己类的2个变量对象，用get获取所有的6个数据，再自己拼String 呗
