在2个表上打印2个标题

Question

大家早上好，

我被指派在java（初学者）上显示一个双面表。我能够获得表格的主体，但我在编码以打印表格标题时遇到问题。第一列应该有“Miles”作为标题，第二列应该有“公里”作为标题。如何打印？

下面是我为表输出所做的代码。

//This program will display 2 tables side by side
//With the use of for or while loop structure

import java.util.Scanner;
public class Lab5 
{
public static void main(String[] args) 
{
final double MILES_PER_KM = 1.61; // miles per km
double kilometers = MILES_PER_KM;



for (int miles = 1; miles <= 11; miles +=2)
{
double km = miles * MILES_PER_KM;
String s = String.format("%3d\t%3.2f", miles, miles*MILES_PER_KM);
System.out.println(s);
}


}//main

}//class

Answer 1

我只会使用printf()之类的东西，

final double MILES_PER_KM = 1.61; // miles per km
System.out.printf("%s\t%s%n", "Miles/hr", "Km/hr");
for (int miles = 1; miles <= 11; miles += 2) {
    double km = miles * MILES_PER_KM;
    System.out.printf("%3d\t\t%3.2f%n", miles, miles * MILES_PER_KM);
}
