如何将输出格式化为列？我有一个基本的知识，但似乎停留在格式下来。我的目标是让它看起来像下面的格式。
Hour Act1 Act2 Act3
1 Sleep
2 Sleep
3 Sleep
4 Sleep
5 Sleep
6 Sleep
7 Sleep
8 Sleep
9 Sleep
10
11
12 Eat
13 Eat
14 Eat
15
16 School
17 School
18 School
19 School
20 School
21 School
22 School
23
24
我的代码：
import java.util.Scanner;
public class DaySchedule {
public static void main(String[] args) {
// Day Schedule
String activity1, activity2, activity3;
int eat, sleep, school, eatstart, eatend, sleepstart, sleepend, schoolstart, schoolend;
Scanner in = new Scanner (System.in);
System.out.println("Enter first daily activity: ");
activity1=in.next();
System.out.println("Enter total hours for activity one: ");
eat=in.nextInt();
System.out.println("Enter starting hour for activity one: ");
eatstart=in.nextInt();
System.out.println("Enter ending hour for activity one: ");
eatend=in.nextInt();
System.out.println("Enter secound daily activity: ");
activity2=in.next();
System.out.println("Enter total hours for activity two: ");
sleep=in.nextInt();
System.out.println("Enter stating hour for activity two: ");
sleepstart=in.nextInt();
System.out.println("Enter ending hour for activity two: ");
sleepend=in.nextInt();
System.out.println("Enter third daily activity: ");
activity3=in.next();
System.out.println("Enter total hours for activity three: ");
school=in.nextInt();
System.out.println("Enter starting hour for activity three: ");
schoolstart=in.nextInt();
System.out.println("Enter ending hour for activity three: ");
schoolend= in.nextInt();
int hour;
int mins;
System.out.println("Day Schedule");
System.out.format("%-3s%-10s%-10s%-10s","Hour ","Activity1", "Activity2", "Activity3");
System.out.format("%n");
for (hour=1; hour<=24; ++hour);
{
System.out.format("%3d",hour);
for (mins=1; mins<=59; ++mins)
{
switch(mins)
{
case 1: if (hour==eat)
System.out.printf("%-3s%-10s","",activity1);
break;
case 2: if (hour==sleep)
System.out.format("%-3s%-10s%-10s","","",activity2);
break;
case 3: if (hour==school)
System.out.format("%-3s%-10s%-10s%-10s","","","",activity3);
break;
}
}
System.out.println();
}
}
}
